We're not sure that cats miss the litter box more in the winter, but we do seem to hear about the problems more at this time of year.

While diseases such as diabetes (which increases urine production) often factor into litter box problems, when the weather is cold, it's a cat's arthritis that may be worsened. Veterinarians know that arthritis is underdiagnosed in cats, largely because owners write off the symptoms as "just old age." And on the human side, we suspect that when the weather turns colder and houses close up for warmth, every little thing starts to annoy us -- like the smell of the litter box, or (worse) the smell of a cat who's not using the litter box at all.

No matter what, though: Don't blame the cat for the problem. Put your detective hat on and get to problem-solving, with the help of your veterinarian. And don't delay: The failure to use a litter box is the top behavior complaint of cat lovers, sending countless cats to shelters every year.

The first step in solving such a problem is to make sure it's not a medical condition -- and that means a trip to your veterinarian for a complete workup. You cannot hope to get your cat using the box again until any health issues have been resolved. Even old-age stiffness can be treated or accommodated, with your veterinarian's help.

If your cat checks out fine, you need to start working to make sure that everything about the box is to your cat's liking. The second rule of solving a litter box problem: If the cat isn't happy, no one will be happy. Here's what to look for.

-- Cleanliness. Cats are fastidious animals, and if the litter box is dirty, they'll look elsewhere for a place to go. Clean the box frequently -- twice a day at least -- and make sure it's completely scrubbed clean and aired out on a weekly basis. Having an additional litter box may help, too. (Multiple litter boxes are recommended for multicat households, since many cats simply will not share.)

-- Box type and filler. Many choices people make to suit their own tastes conflict with the cat's sense of what's agreeable. A covered box may seem more pleasing to you, but your cat may think it's pretty rank inside or scary. Likewise, scented litters may make you think the box smells fine, but your cat may disagree -- not only is the box dirty, he reasons, but it also has this extra "clean" odor he can't abide. Start with the basics: a large box with unscented, clumping-style litter.

-- Location. Your cat's box should be away from his food and water, in a place he can get to easily and feel safe in. Consider a location from a cat's point of view: Choose a quiet spot where he can see what's coming at him. A cat doesn't want any surprises while he's in the box.

Make the area where your cat has had mistakes less attractive by cleaning it thoroughly with a pet-odor neutralizer (available from pet-supply retailers). Discourage reuse by covering the area with foil, plastic sheeting or plastic carpet runners with the points up.

If changing things around doesn't clear up the problem in a healthy cat, you may need to retrain him by keeping your pet in a small area such as a guest bathroom for a couple of weeks.

Make sure the area you choose has no good options besides the litter box -- no carpet, no pile of dirty laundry. Block off the bathtub or keep an inch of water in it to discourage its use as a place to go. After your cat is reliably using the litter box, let him slowly expand his territory again. As long as you keep up your end of the bargain and keep the litter box clean and safe, you have a good chance the good behavior will become permanent.

If you just can't seem to get the problem resolved, ask your veterinarian for a referral to a veterinary behaviorist. These veterinarians are skilled in behavioral problem-solving and are able to prescribe medications that may make the difference during the retraining period.

Q&A

First-aid classes highly recommended

Q: I saw Dr. Becker on "The Dr. Oz Show" demonstrating CPR for dogs and cats. Is that something pet lovers need to know? I mean, really, I don't think I want to put my mouth over my dog's nose. But I guess I would if I had to. Are there classes in this? -- F.P., via e-mail

A: Yes, there are classes you can take in CPR and first aid. The American Red Cross offers them, and some veterinarians also provide basic first-aid training as part of their practices.

As for the rest of your questions, I reached out to our Pet Connection ER guru, Dr. Tony Johnson of the Purdue University School of Veterinarian Medicine.

"I have had many pet owners tell me that they have performed 'mouth to snout' resuscitation on their pets while en route to the hospital. Whether they have really saved their pet's life or just caused their pet to think, 'Dude, what are you doing?' is still open for debate," he writes. "The anatomical differences between people and pets makes actual CPR difficult -- it is almost impossible to form a tight seal over their mouth and nose; air blown in the nose usually just comes out the mouth rather than going down into the lungs.

"Also, many pet owners' expectation of survival after CPR has been unrealistically set too high by TV -- everyone seems to be OK after CPR when a happy ending is called for in the script," continues Dr. Johnson. "That's rarely the case in true life, and even less so with pets."

So does that mean you shouldn't bother to learn more about emergency care? That's not Dr. Johnson's opinion at all. Your pet will have a better chance at survival in an emergency the more you know about what to do, after all. (And the "what to do" should include knowing the location, directions to and phone number of your nearest emergency-care veterinary clinic.)

"Knowing CPR is fine," says Dr. Johnson, "but more general first-aid information is even better to know. I encourage pet owners to take a basic first-aid course, or brush up on pet first aid once they know it through available books and good Web sites. Knowing how to stop bleeding, treat choking, prevent hypothermia and safely transport a pet to the hospital are essential to know -- and may make a life or death difference for your pet one day."

So there you have it! -- Dr. Marty Becker

Exercise is for the dogs

-- Dogs are the key to exercise motivation. A survey from the United Kingdom found that 3,000 dog owners spent an average of eight hours and 11 minutes weekly exercising their pets. The survey also looked at 2,000 pet-less people and found their average weekly exercise at only one hour and 20 minutes. Even more, 86 percent of pet owners said they enjoyed walking their dogs. Dog owners were also less likely to come up with excuses not to exercise than those who don't own dogs. Only 16 percent of people said they enjoyed working out in the gym.

-- The world record for the most tennis balls held in the mouth of a dog is five, a record held by Augie, a golden retriever from Dallas who successfully gathered and held five regulation-sized tennis balls.

-- A horse's whinny not only provides information on sex, height and weight, but also plays an important social role. According to a study in the journal Animal Cognition, the whinny is more important than visual cues to horses. Whinnies vary in frequency according to sex, with stallions having lower-pitched frequencies, and mares and geldings having a higher frequency. Horses were also able to identify the social status of the horse neighing, whether or not the study horse knew the neighing horse. Horses recognize their equine friends as long as they are within hearing distance.

-- Egyptians revered cats for their relation to their cat goddess, Bastet. Whenever a cat would die, ancient Egyptians were said to shave their eyebrows in mourning. -- Dr. Marty Becker and Mikkel Becker Shannon

THE SCOOP

Little dogs can have big problems

While no one can say how many small dogs there are, any casual observer will notice shoe-button eyes peering out from more shoulder bags these days.

Small breeds such as Yorkshire terriers have boomed in popularity, according to purebred dog registries. But that doesn't take into account popular mixes such as Yorkipoos (Yorkie-poodle crosses) and Maltipoos (Maltese-poodle crosses). And Chihuahuas have become so overly popular that the best place to adopt one is at a shelter!

But small dogs require special care. The list of things that can go wrong with tiny dogs is a long one, and veterinarians see it all: Defective knees, hips and shoulders. Heart and liver problems. Collapsing cartilage in the neck. Troublesome teeth. Overall fragility, including easily broken bones.

Some problems can be prevented through ethical breeding practices such as screening for genetic defects or with more careful handling to prevent injury. But many medical issues just come with being little.

The most vulnerable of these dogs are the smallest ones. Health problems don't stop the unscrupulous from breeding, but they should stop dog owners from buying. Pet lovers will do best by avoiding those who sell the tiniest of the tiny, or sell any small dog too young. Reputable breeders usually won't let small-breed puppies go until they're 12 weeks old, since younger puppies can die if not fed every four hours.

Tiny dogs can also be hard to house-train, since they have small bladders and need to go outside more often.

That doesn't mean they're not wonderful pets -- they are! -- but it does mean that owning a small dog means learning about their special needs so they can stay healthy and happy. -- Dr. Marty Becker

BY THE NUMBERS

People first, but not by much

If you had to choose only one companion if stranded on a deserted island, what would it be? According to a survey of pet lovers, the highest number would choose a person over a particular kind of pet -- but if you tally all pets together, people lose. The results:

Human 47 percent

Dog 40 percent

Cat 10 percent

Other 2 percent

None 1 percent

ON GOOD BEHAVIOR

Cats need more variety

Cats may become fixated on certain food shapes and textures, not accepting anything unfamiliar as food. When cats eat only certain textures and tastes of food, they'll suffer if put on special diets or if a favorite brand becomes unavailable. And good luck trying to trick the food-fixated cat by hiding pills!

Avoid the problem by feeding kittens and cats a variety of foods. Introduce new foods by hand when the kitten or cat is very hungry. Mix a small amount of new food in with favorites to encourage acceptance.

Feed kittens and cats a wide selection of foods in various flavors, sizes, textures and shapes. Vary treats and flavors to keep your feline flexible in the food department.

Cabin fever can be the bane of an indoor cat's existence, but it doesn't have to be that way.

You don't have to open the door to the great outdoors to provide your cat with a more interesting life. In fact, by just looking at your home from a cat's point of view and adding a few environmental enrichments, your cat can be both safe and happy indoors. Here are five easy ways to get going:

-- Think vertical. Cats love to climb, so give them the opportunity. Cat trees mounted floor-to-ceiling, wrapped with sisal rope and studded with platforms for perching, will give your cat the opportunity to look down on the rest of the world. This is especially satisfying if there are dogs in the household, because what cat wouldn't like to look down on the dog?

-- Add toys. The cat with the most toys wins. Every indoor cat should have toys for batting around, toys for chasing, toys for hiding in and toys for interactive play. And don't forget that some of those toys ought to have catnip in them. While not all cats can enjoy the fragrant herb, those who do find it blissful in the extreme. If your cat is a catnip junkie, indulge him frequently. Rub fresh catnip onto cat trees or scratching posts, or stuff it into toys. It's perfectly safe for your cat to enjoy the buzz.

Some of the most enjoyable toys for both people and cats are the interactive ones. Every cat lover should have a "kitty tease" toy, typically a flexible rod with a line that ends in something furry or feathery to engage a cat's prey drive. Other interactive toys include gloves with goodies dangling from the fingertips, or laser pointers that offer cats a spot of light to chase. (Just be careful not to aim the beam in your cat's eyes.)

-- Provide rooms with views. No matter how big your house, your indoor cat will know every one of its sights and sounds within just a few days. Provide a little visual stimulation by putting a bird feeder outside a window fitted with a cat-sized ledge for comfortable viewing.

Be aware, though, that a view of the world isn't always going to work for your cat. If your yard is attracting other cats from the neighborhood, your own cat may become frustrated by seeing them, and he can even turn that frustration into attacks on people in the house. Blocking visiting cats from your yard or discouraging them with sprinklers may solve the problem. Otherwise, you may have to make certain windows off-limits to your own cat.

If a window view isn't going to work, try a TV. A few companies offer DVDs for cats. Pop one of these in, and your cat can be entertained with a lively mix of feline-friendly images and sounds, including those of birds and rodents.

-- Go green. Cats love nibbling on plants. Any decent feline reference book will provide a list of which plants should not be in a pet-friendly house, or visit the Animal Poison Control Center (www.aspca.org/apcc) for information on dangerous plants.

After you get the unsafe plants out of the way, protect your decorative houseplants by hanging them up or otherwise putting them out of reach. Keep cats from digging in your decorative pots by putting a layer of small, rough stones over the dirt. You can then add a collection of accessible plants for your cat to nibble on, such as grass shoots, or to enjoy rubbing, such as catnip, valerian or rosemary.

-- Give face time. Of course, one of the best things you can do for your indoor cat is to spend time with him. Playing, grooming, petting or just plain hanging out -- it's all good. Your cat loves you and loves spending time with you.

Keeping a cat inside is one of the best ways to ensure a long and healthy life, but it won't be that happy an existence unless you're going to add some interest to the surroundings. It doesn't take much in the way of time or effort, so get going. Your cat will thank you!

Q&A

Tips for getting fussy cat to eat

Q: I have a finicky cat. I know, I know: Cats are supposed to be finicky, but I'm so tired of trying to get this cat to eat and throwing away food afterward. The vet says he's fine. Suggestions? -- G.W., via e-mail

A: Although some cats have never met a dish of food they didn't love, others are very picky about what they eat. Feeding cats a wide variety of flavors and brands can help keep them from fixating on one particular food. Warming canned food to just about room temperature can also tempt a finicky feline.

Be aware, however, that your cat may not be as finicky as you think. If you leave dry food down all the time, he may be nibbling constantly throughout the day and thus never eating very much in any one observed sitting. The amount of food any one cat in a multicat household eats can be especially difficult to determine if food is always available. Cats with access to the outdoors may additionally be mooching off the neighbors or supplementing the rations you give him by hunting.

Finickiness in a healthy cat is not a reason for concern as long as your pet's not losing weight. A half-pound or even a pound gradually up or down is no big deal, but more than that and you need to call your veterinarian. Weight loss is often one of the first indications that something is wrong with your cat. -- Dr. Marty Becker

Q: Our house is on the dry side even though we run a humidifier in winter. My cat's skin has been extremely dry. Is there something I can do to eliminate this massive white dander he is scratching out? -- P.T., via e-mail

A: Don't be so certain the low humidity in your house is causing the problem. After all, cats are descended from desert-dwelling creatures, and low humidity alone shouldn't cause a massive amount of flakiness.

See your veterinarian to determine what's causing your pet's skin to be so flaky.

By the way, other pets actually do have a problem with the dry air of the modern home, most notably birds. Many species of pet parrots originally came from hot, humid environments. For these, dry air presents a problem and may contribute to feather-picking. That's why parrots need to be offered frequent opportunities to get damp, such as by being misted or being allowed to bathe. -- Dr. Marty Becker

THE BUZZ

Mixed-breed cats are most popular

-- Most cat lovers have never been that interested in pedigrees: Plain ol' domestic cats of all backgrounds, markings and coat lengths are by far the most popular. Among cats with papers, the most popular breed is the Persian, followed by the Maine coon, the exotic (a shorthaired Persian), Siamese and Abyssinian. In the United Kingdom, what Americans call DSH (domestic shorthair) and DLH (domestic longhair) cats go by the much more endearing name of "Moggy."

-- Reports of a flood of Chihuahuas in shelters has prompted the relocation of many of these dogs to parts of the country where they remain in demand. Newspaper reports show that Chihuahuas and Chi mixes are the top dog in Los Angeles shelters and make up one-third of the dogs for adoption in San Francisco shelters. Why the little dogs are so popular is a matter for speculation, but some blame the influence of celebrities such as Paris Hilton and movies such as "Legally Blonde" and "Beverly Hills Chihuahua."

-- The New York Racing Association will levy harsh penalties on owners and trainers who either directly or indirectly sell a horse for slaughter, revoking the right to book stall space at the association's tracks -- Aqueduct, Belmont and Saratoga. In the meantime, Reuters reports that horsemeat is falling off the menu in France, a trend that may finally force North America to find more humane solutions to the problem of unwanted horses.

-- Dog breeds at animal shelters are misidentified about 75 percent of the time, according to a study by Canada's College of Veterinary Medicine at Western University. The findings bring into question the ability of animal control officials to ID -- and mark for killing -- shelter "pit bulls" in jurisdictions where they are banned. -- Dr. Marty Becker and Mikkel Becker Shannon

THE SCOOP

Muddy paws can be tamed, even in winter

The best way to keep floors clean is to never let them get dirty. And that means catching those muddy paws before they come inside. Here are some tips:

-- Use mats. Put washable mats both inside and outside the door. A small door mat can be jumped over, so go for something larger, at least during the rainy season. The wider the area of matting, the more chance you have of every paw hitting the mat at least once. Try a 3-foot-by-5-foot black industrial mat on either side of the door: It catches lots of mud and hoses off easily outside.

-- Teach dogs to wait for wiping. It's not difficult to teach a dog to wait on the mat for a paw cleaning. If you're patient and positive, you'll be able to teach your pet to offer each paw in turn and stand patiently while you towel it off.

-- Save your old towels. When towels get too ratty for guests to see, save them for use with your pets. Old towels may be ugly, but they are great for wiping paws, drying fur and even swiping a muddy paw print off the floor. You can also find super-absorbent towels and mitts made specifically for wiping paws. If you do need to buy paw wipes, then check prices on shop towels.

-- Never let a mess settle in. If a muddy paw gets past you, don't delay your cleanup. While this isn't such a hard-and-fast rule for such easy-clean surfaces as tile and hardwoods, it's an absolute commandment when it comes to carpets. Keep cleaning supplies well-stocked and at hand, and be sure to jump on a muddy paw print -- or any pet mess -- before it can set. -- Gina Spadafori

PET TIP

Bigger pet cages are always better

If you had to spend your life in a cage, you'd want it to be as big as possible, wouldn't you? Then why settle for a tiny cage for your bird, reptile or small mammal?

Forget the pet store's labels or recommendations. For them, cage size recommendations are based on what they believe a customer will pop for -- in other words, the cheapest option available.

Think bigger! Go one size larger than the pet-store recommendations. For a budgie, for example, get a cage sized for a cockatiel, while cockatiels should be in cages sized for small parrots.

While you're introducing that larger cage to your pet, don't forget to enrich the environment with a variety of toys (and perches, for birds). Life in a cage isn't natural for any animal, so the least you can do is make that life more interesting. -- Gina Spadafori

Are pets on your list of New Year's resolutions? They should be, along with plans for making the world a little bit better not only for your own animals, but also for others in need. With this in mind, we're again sharing some of the best ideas of our readers.

Although problems can seem overwhelming, especially when it comes to animal cruelty or homeless pets, the fact is that every little bit helps. After all, if every one of us animal lovers did one small thing a couple of times a year, the total effort would be grand indeed.

Here are a few suggestions for helping animals in the months to come:

-- Take better care of your own animals. Studies show that, just like many of us, a lot of animals desperately need to lose weight and exercise more. Remember: Food is not love, and lay off the treats. You and your pet will both do better with a walk or some otherwise active playtime together.

Don't neglect other aspects of preventive health care. Use your pet's regular exams to go over those areas that need improving. In addition to weight loss and exercise, your veterinarian should evaluate your pet's vaccination schedule, dental health and parasite-control strategies. Preventive health care saves money, makes your pet more comfortable and helps extend life span. Make that veterinary appointment today!

Part of taking better care of your own pet is making sure your animals are "good citizens" to your neighbors. Don't let your cats roam or your dogs bark constantly. In addition to being inconsiderate, people who allow their animals to be a nuisance give ammunition to communities looking to pass laws against pets.

-- Help others take better care of their pets. If you have a friend, neighbor or relative who is having difficulty caring for a pet because of advanced age or illness, offer to help out. Pets are extremely important to those who are cut off from social activities. Helping people keep their pets is a kindness to both pet and pet owner.

What can you do? Pick up food or litter, or offer to take the pet to the veterinarian when needed. Many times, people who rely on others for assistance are reluctant to ask for more help on account of a pet. So ask if you can help. After all, if you're already going to the pet-supply store or veterinarian, is it really that much trouble to pick up some extra supplies or to stay for an additional appointment?

-- Make a call for animals. Animal cruelty should not be tolerated, not only for the animals but also because of the proven link between animal cruelty and crimes against people. Too often, though, animal cruelty is shrugged off by the judicial system as a lesser crime.

Don't accept the attitude that animal cruelty is a normal part of adolescence. Call, e-mail and write to prosecutors and judges in animal cruelty cases. Demand that young adults get the help they need to break the cycle of cruelty and that adult offenders are punished to the fullest extent of the law. Public opinion counts in these cases!

-- Pay to spay. Don't place an animal in a new home unless you've made sure the pet won't reproduce. You may think you're doing a good deed in finding a home for a pet you cannot keep, or for a litter of kittens born in your garage to a semi-wild mother cat. But if you don't pay to spay, you really aren't helping.

Instead of placing a pet for free, spay or neuter the animal and then charge an adoption fee to cover the cost of the procedure. You'll save the adopter time and will ensure that the pet you place won't add to the overpopulation problem.

-- Help a shelter or rescue group. Volunteers are always needed to help with the animals in the shelter or to foster pets who need a home environment. But if you don't want to contribute on a regular basis, then see if you can help on a short-term project. Many groups have fundraisers throughout the year. They need volunteers to help with ticket sales, setup, concessions and cleanup. You can also help by finding out what your local shelter or rescue groups need in the way of services or supplies, and then make calls to ask for donations.

Shelters are in constant need of pet food, litter, old newspapers and towels, as well as office and janitorial supplies and building materials. Get a wish list from your shelter and get to work!

Happy New Year from all of us at PetConnection, and keep those good ideas coming.

Q&A

All pets deserve owner's attention

Q: I wholeheartedly agree with your stand against "outside dogs" and hope that people take your advice not to get a dog if it is not going to be part of the family. How sad it is to think of all the lonely dogs outside alone year after year, especially in the coldest parts of the country. What's the matter with people, anyway?

Could you mention one more reason not to abandon a dog to the outdoors? In addition to all the points you made, these dogs are probably denied prompt and proper medical care because their owners do not notice their ailments. -- K.H., via e-mail

A: Happily for the dogs of the world, there are lots of pet owners who agree that dogs are not happy living their lives completely alone outside. Their numbers are bolstered by people who agree for a different reason -- they live near outdoor dogs and have to listen to the barking of these neglected pets day and night.

Humane societies, behaviorists and other experts have long agreed that making a dog part of the family makes them not only happier, but also less likely to be a nuisance or a danger. This is especially true if the dog is maintained outside on a chain.

And yes, I've neglected in the past to mention your point that dogs who live completely outdoor lives may not get the attention they need when it comes to medical care. That's because it can be difficult to spot the sometimes subtle early signs of serious illness in an animal who isn't living underfoot.

Out of sight, out of mind applies to other pets, too: For example, cats who roam freely and just "check in" for meals may not get the attention they need to spot health problems early. Inside or out, cats can be difficult to read, which is one reason why their medical problems are so often overlooked.

All pets deserve good care from loving owners. Make sure yours get what they need to thrive, in thanks for the love and companionship they provide us. -- Gina Spadafori

THE BUZZ

Owners can prevent canine aggression

-- An owner's influence rather than a dog's breeding largely determines whether or not a pet will be aggressive. A study published in the Journal of Animal and Veterinary Advances found that external, modifiable and owner-dependent factors influence a dog's aggression to a greater degree than a dog's breed, contradicting widespread beliefs that dogs such as pit bulls or Rottweilers are hard-wired for aggression. The researchers found that factors leading to aggression include first-time ownership; failure to provide obedience training; spoiling or pampering the dog; buying a dog as a present, a guard dog or on an impulse; spaying female dogs; leaving the dog with a constant supply of food; or spending little time with the dog in general or on its walks. More than a third of dominance aggression in dogs stems from a lack of obedience training or for doing only the minimum amount of training. The study also found that male dogs are more likely to be aggressive; however, dog-related factors are minimal compared to the factors that owners can control.

-- The closest living relative to the human is the chimpanzee, which is followed closely by the gorilla. Humans and chimpanzees divided from their common ancestor 7 million years ago, and gorillas and humans split 3 million years before that, according to National Geographic.

-- Asthmatic cats are allergic to humans, according to a study by feline clinicians at the University of Edinburgh's Hospital for Small Animals. Human lifestyles may contribute to asthma attacks in felines with cigarette smoke, dusty houses, human dandruff, pollen and certain types of cat litter triggering attacks by creating inflammation in cats' airways. One in 200 cats suffers from asthma, which causes coughing, wheezing and shortness of breath. Household irritants worsen the disease with so-called Oriental breeds, like the Siamese, being more prone to having asthma. Simple changes such as changing litter box material to a paper-based product can improve asthma in cats.

-- Arlington National Cemetery has many has a few non-human inhabitants, including Black Jack, the horse who took part in the funeral procession following the assassination of President John F. Kennedy. Horses are still part of daily routine at the memorial: Horses pull caissons bearing flag-draped caskets, with as many as 27 burials occurring five days each week, according to USA Today. -- Dr. Marty Becker and Mikkel Becker Shannon

THE SCOOP

Time for the New Year's 'neck check'

Checking your pet's collar and tags annually will ensure that an important safety measure is in place should you and your pet ever need it.

Start your "neck check" with a look at your pet's collar. A properly fitted collar is important, but so too is the right type. For dogs, a buckled or snap-together collar made of leather or nylon webbing is the best choice, and the proper fit is comfortably close but not too snug. Make sure your dog's not wearing a "choke" collar. These are for training and walking only, and they pose a life-threatening hazard if left on an unsupervised dog. Cats should wear a collar with an elastic section that will allow your pet to wriggle free if he gets caught on something.

If you do have the right kind of collar on your pet, take a minute to look at the holes and the fasteners. The collar is weakest at these spots, so if you see signs of excessive wear or strain, you'll need to replace the collar soon.

If the collar passes muster, it's time to look at the tags. A license is great, but since many lost pets are picked up by people in the neighborhood, it's a good idea to supplement the license with an ID tag that has a couple of phone numbers -- yours and the number of a friend or relative. Check to make sure the information is current and legible, and if not, make a note to order a new tag right away. -- Gina Spadafori

THE SCOOP

You'll never find lobe on a bird's ear

The avian ear, like all of a bird's anatomy, is streamlined for flight, so you won't find an earlobe on a bird. Instead, look for a swirl of soft, protective feathers in the place where you think the ear should be. Many pet birds love to have the area around their ear canal scratched.

Birds don't hear high- and low-pitched noises as well as we do, but within the range they do hear, they are able to discern more details. The song of a finch would have to be recorded and played at about one-tenth speed for us to be able to hear the richness and detail of sound that a bird can. -- Dr. Marty Becker
