Better health and care for cats is a lodestar for Winn Feline Foundation

When you feed your cat; purchase a Maine coon or ragdoll kitten who doesn’t have a mutation for hypertrophic cardiomyopathy, the most commonly diagnosed form of heart disease in cats; or have your cat’s diabetes reversed through a change in diet, you’re benefiting from research funded by the Winn Feline Foundation (winnfelinefoundation.org), which is celebrating its golden anniversary of helping cats.

The organization, founded in December 1968 with a $125 donation from the Cat Fanciers Association, has grown into an internationally recognized force for feline health research and education. More than $6 million later, Winn has supported scientists studying chronic kidney disease in cats, feline infectious peritonitis and stem cell therapy for managing inflammatory conditions such as chronic gingival stomatitis. Its successes are well-known to informed cat lovers.

“Their work on kidney atrophy and disease in Persians and exotics is important and gives me hope that there will be a cure someday for polycystic kidney disease (PKD),” says Dee Dee Drake, executive director of Calaveras Humane Society in California.

Discoveries by Winn-funded researchers now allow cat breeders to test for PKD and breed away from it in their lines. Testing also allows the disease to be identified earlier in a cat’s life. The disease can’t be halted, but early identification means cats can be treated for loss of kidney function at an earlier stage of disease. And because Persians have been used in breeding programs for other breeds, such as exotics -- the Persian’s shorthaired cousin -- those breeds benefit as well.

Cat breeder Lorraine Shelton cites evidence-based research showing that early-age spay and neuter surgery is safe in cats. While there is evidence in dogs that early-age spay and neuter poses health risks, studies in cats have not uncovered negative side effects.

But for many cat owners, the word most associated with Winn is "taurine." In 1987, the organization took a chance on veterinary cardiologist Paul Pion’s hypothesis that a deficiency of taurine in cat foods was linked to the high incidence of dilated cardiomyopathy and funded his research on an emergency basis. He was correct, and now cat foods are formulated to meet the feline need for taurine. Today, most veterinarians don’t see cats with dilated cardiomyopathy except in unusual situations, says Vicki Thayer, DVM, Winn’s executive director.

Pain relief and the effects of stress on cats are also important to feline health and welfare. At Colorado State University College of Veterinary Medicine, Elena Contreras, DVM, and Michael Lappin, DVM, are studying whether concentrations of cortisol -- one of the “stress” hormones -- in fur and nails can provide veterinarians with a simple, accurate way to measure and diagnose chronic stress in cats.

And at North Carolina State University, Santosh Mishra, Ph.D., and Duncan Lascelles, Ph.D., MRCVS, are using a grant from Winn to study degenerative joint disease-associated pain and hypersensitivity in cats. Much of Dr. Lascelles’ research focuses on ways veterinarians can recognize and manage pain in cats.

“These types of studies are critical to veterinarians who want to reduce the stress cats experience in the exam room as well as provide better pain relief for cats with osteoarthritis, which is a more common problem than people realize,” says Marty Becker, DVM, founder of the Fear Free organization, which has the goal of reducing fear, anxiety and stress associated with pet health care.

Starting this month, Winn begins a focus on raising money for research into chronic kidney disease, a common problem in aging cats.

“A lot of people have shown that they are concerned about chronic kidney disease in cats, so we want to do a matching fund to see if we can support more kidney-disease research,” Dr. Thayer says.

Q&A

What causes dog

to lick legs, feet?

Q: I have a dog who licks her feet and legs too much. She is groomed every month, and I give her daily dietary supplements. Her vet says she might have back leg problems. Is she in pain?

A: Dogs lick themselves for lots of reasons. Sometimes it’s a result of being anxious, stressed or bored. Dogs with separation anxiety may lick themselves because the behavior releases soothing endorphins that help the dog feel calm. Conflicts with other animals or changes in household routine may also cause “stress-relief” licking. Some dogs lick their paws because they don’t have anything better to do.

Your veterinarian is correct that licking can also be a sign of an underlying health problem. It’s not unusual for dogs to lick areas of the body that are itchy or painful. Dogs who lick their paws and legs may be attempting to relieve the awful itch of skin allergies or bacterial or fungal infections or the joint pain from arthritis, which can settle in the carpus (wrist), stifle (knee), elbows, hips and lower back.

Anytime a dog licks excessively, he should be seen by the veterinarian to rule out a health problem, such as one of the many itchy skin diseases or a painful condition such as arthritis. Be prepared to tell your vet about the food and supplements your dog receives, his daily routine and the detergents and household cleaners you use. The vet may run diagnostic tests that include skin scrapings, a fungal culture or blood work.

If a thorough history and physical exam don’t turn up any cause for the licking, consider your dog’s lifestyle. Does he need more physical and mental stimulation? Consider taking him on walks in new areas, letting him take his time sniffing instead of rushing him along, introducing him to a fun dog sport such as nose work or rally, or rotating several interesting puzzle toys. -- Dr. Marty Becker

Pets grieve, too.

Know the signs

-- Has your dog or cat lost a friend? The death of a human family member or a fellow pet can send animals into a state of grief. How animals mourn is similar to the way people react to the loss of beloved companion: They may mope, lose their appetite, be unwilling to play, or sleep more. Sometimes they curl up with clothing that bears the missing person’s scent or move to the missing animal’s sleeping spot. These behaviors or more subtle changes in behavior are clues that a pet has the blues. Help him cope by maintaining a normal routine, giving some extra-special attention more frequently and remaining patient.

-- If you’re making your first trip to the veterinarian with a new kitten, some preparation can help the visit go smoothly. If possible, a preliminary visit to familiarize yourself with the clinic setup can let you scope out such things as whether your kitten might encounter dogs in the waiting room. Plan to have him in a cozy carrier spritzed with soothing feline pheromones where he’ll feel secure -- not in your arms, where he could squirm and scratch in an attempt to escape. If a checkout visit isn’t possible, leave your kitten in the car, inside her carrier, while you go sign in. Ask the receptionist to call or text you when they’re ready to take you and Fluffy straight to the exam room. Don’t forget plenty of treats to help distract her during the exam and create positive associations with the experience.

What’s causing unusual cases of dilated cardiomyopathy in dogs? Dietary ingredients, lack of taurine are potential culprits, but the answer remains elusive

By Kim Campbell Thornton

Andrews McMeel Syndication

For several months, the United States Food and Drug Administration’s Center for Veterinary Medicine, in partnership with independent diagnostic laboratories and veterinary cardiologists and nutritionists, has been investigating reports of a trend that began at least two years ago: Some 150 or more dogs (and at least seven cats) that ate pet foods containing plant-based sources of protein among their main ingredients have developed dilated cardiomyopathy (DCM).

Canine DCM is a disease of the heart muscle that causes the heart to enlarge and decreases its ability to pump blood, often leading to congestive heart failure. It has a number of possible causes, including genetic predisposition, infection or toxins, and diet -- in particular, a lack of taurine. Here’s what is known so far.

The reported cases of DCM are unusual because they are occurring in breeds such as golden and Labrador retrievers, whippets, a Shih Tzu, a bulldog, miniature schnauzers and mixed breeds, none of which are typically prone to the genetic form of the disease. (Breeds genetically predisposed to DCM include Doberman pinschers, Great Danes and boxers. Cases of DCM responsive to taurine supplementation have been reported in cocker spaniels.)

Reported cases are also unusual because many of the dogs consistently ate what are popularly described as “grain-free” foods, with high levels of legumes such as peas, beans and lentils; legume seeds (known as pulses); potatoes; or foods with exotic protein sources such as kangaroo.

Investigators have so far been unable to determine why these ingredients might be linked to cases of DCM. In some cases, dogs had not eaten any other food for months or years before exhibiting signs of DCM.

At least four dogs in reported cases had low blood levels of taurine, an amino acid that helps power “excitable” tissues such as the brain, skeletal muscles, retina and heart. Taurine deficiency is documented as a potential cause of DCM.

That said, in four other cases, the dogs had normal blood taurine levels. In some cases seen by cardiologists, though, dogs who were not taurine deficient improved with taurine supplementation and diet change, according to an article by veterinary nutritionist Lisa M. Freeman, a member of the clinical nutrition service at Cummings Veterinary Medical Center at Tufts University. It may be that individual dogs have different taurine requirements based on breed, size or some unknown factor.

The FDA notes that other factors could include nutritional composition of the main ingredients or how dogs process them, sourcing or processing of primary ingredients, and amount of the ingredients used. Various proteins, including meat proteins, have different nutritional profiles and digestibility. Studies have found that certain large dogs fed commercially available complete and balanced lamb and rice diets may have increased risk of developing taurine deficiency-induced DCM. A 2007 study found that giant dogs took in less taurine than small dogs, possibly because of a slower metabolic rate.

Because it is not yet understood how or if grain-free diets are linked to cases of DCM, the FDA recommends consulting a pet’s veterinarian about whether to change a diet. Dogs or cats with signs of DCM or other heart conditions -- such as low energy, cough, difficulty breathing and collapse -- should be seen by a veterinarian immediately. Guidelines released by veterinary cardiologists and nutritionists advise testing blood taurine levels of dogs diagnosed with DCM and changing the diet based on consultation with a veterinary cardiologist. A taurine supplement may be recommended. Improvement after dietary change and supplementation can take up to six months. Report possible dietary cases of DCM to the FDA.

Ways to manage

cat allergies

Q: My cat is allergic to everything: fleas, food, pollen, etc. She has scratched and bitten all the fur off her belly and chews at her legs. How can we manage her condition and help her stay comfortable?

A: That’s a triple-whammy! We often see flea-bite allergies in cats, and environmental allergies aren’t unusual either. Food allergies are less common, but they definitely occur. Signs for all three can be similar: scratching, biting, rubbing and grooming excessively. Other signs include sneezing, watery eyes and ear infections. All of those things add up to one seriously uncomfortable cat!

Treatment is individualized to each cat because they all have different signs. Beyond corticosteroids, your veterinarian may prescribe antihistamines, cyclosporine and allergy shots. All of these may play a role in helping to reduce your cat’s intense itching.

Used with antihistamines, essential fatty acid supplements may contribute to itch relief, too, according to some veterinary dermatologists. In dogs, applying EFAs topically has been found to help improve what’s known as barrier function -- the skin’s ability to repel pathogens that can aggravate atopic dermatitis. We don’t know if that works in cats, but it’s something to ask your veterinarian about.

It can be challenging and time-consuming to determine exactly what your cat is allergic to so you can get her on a program to keep symptoms under control. It may be necessary to restrict her diet -- called an elimination diet -- and then gradually add back specific ingredients to figure out which ones are setting off her allergies. Be prepared for the process to take as long as several months. If possible, enlist the services of a board-certified veterinary dermatologist who can perform allergy testing and recommend other environmental or dietary changes, as well as appropriate medication. Your veterinarian may be able to refer you to someone locally, or you can find one through the American College of Veterinary Dermatology. -- Dr. Marty Becker

Dose noise-aversion

drug carefully

-- If your dog is fearful of loud noises such as thunder, fireworks, vacuum cleaners, gunshots or traffic sounds, you may be giving him a medication called Sileo (dexmedetomidine), which is FDA-approved to treat noise aversion. The oromucosal gel is administered to the dog’s gums with a special multidose syringe. The FDA warns that dogs can receive too much of the drug if the syringe isn’t set up properly. To prevent accidental overdoses, be sure you understand how to determine the appropriate dose based on your dog’s weight, lock the syringe in place and deliver the drug so the dog doesn’t swallow it. No deaths have been reported, but possible effects of an overdose include sedation, lethargy, sleepiness, slow heart rate, shallow or slow breathing, difficulty breathing, impaired balance, low blood pressure, muscle tremors and loss of consciousness.

-- Love the look of a longhaired cat with a pointed coat? The Birman may be the breed for you. The sweet social butterflies love following their humans around the house and settling into a lap whenever possible. Their silky coats are easy to groom and don't have an undercoat to form mats and tangles, though they still need daily combing to remove loose hair and prevent hairballs.

-- A new system being tested at the port in Mombasa, Kenya, may allow specially trained dogs to search large shipping containers for contraband ivory, rhino horn and other wildlife products using only a small air sample. Called Remote Air Sampling for Canine Olfaction (RASCO), the system will draw air from specific containers and pass it through filters that are then presented to the dogs, trained to sit if they scent anything illicit. The technique could allow the dogs to check many more containers daily, reducing trade of illegal wildlife items. -- Dr. Marty Becker, Kim Campbell Thornton and Mikkel Becker

Common-sense care keeps pets healthy and injury-free

Andrews McMeel Syndication

If you’re a parent, you’ve been swamped with back-to-school preparations. If you’re a pet parent, it’s also a good time of year to practice some preventive care to keep your dog or cat healthy.

Inoculations. Pets need vaccinations early in life -- usually a series of “core” vaccines for parvovirus, distemper, adenovirus and rabies for puppies, and feline herpesvirus, feline calicivirus, feline panleukopenia virus, feline leukemia virus and rabies for kittens -- followed by a booster when they are 1 year old. Ideally, puppies should receive the final parvovirus and distemper vaccinations when they are at least 16 weeks old because they may not develop a good response to the vaccine before that age.

After that, booster shots are recommended only every three years. Better yet, ask your veterinarian to “titer” your pet every three years to see if the immunity from the vaccines still holds. The rabies vaccine is an exception: Most states require it triennially for dogs and do not allow exceptions even if a titer shows the dog is still protected.

Talk to your veterinarian about whether your pet needs any “non-core” vaccinations for diseases that may be seen in your area or that are specific to an animal’s lifestyle. For instance, a canine influenza vaccine may be a good idea for dogs who travel frequently to dog shows or other competitions where they are in contact with other dogs, or who are boarded or go to dog parks. Farm dogs or dogs who frequent areas where there are wild mammals may benefit from a vaccination for leptospirosis. In cats, the Bordetella vaccine is not routinely recommended unless they are at high risk of exposure from being in crowded environments.

Injuries. Not every injury is preventable, of course, but taking steps to reduce their likelihood helps. Pet-proofing your home and yard is the most effective way to prevent accidents. Better yet, it doesn’t cost anything.

Indoors, make sure medications are well out of reach. Poisonings from human medications are one of the top reasons for calls to pet poison control hotlines. Just 15 seconds is all it takes for dogs to break into childproof bottles. The same goes for trash and foods that could cause digestive upset.

Outdoors, walk the perimeter of your yard to check for weak spots in fences or gates, and repair them. Pull up mushrooms and toadstools that might attract pets who are willing to down anything that looks edible. If you live with one of those animals, avoid putting out snail bait, rat poison or other toxic substances; it’s not worth the risk of a trip to the ER or, worse, a death. Some owners teach their “I’ll-eat-anything” dogs to wear a basket muzzle when they’re outdoors so they don’t swallow sticks, pine cones, toxic mushrooms or other objects that can cause problems.

Part of pet-proofing includes teaching animals to respond quickly to the cues “come” and “leave it,” which can prevent them from running into the street or nabbing something tasty but toxic.

Internal and external parasites. Get an update from your veterinarian about the latest in parasite prevention. Products are available that repel ticks and fleas and prevent roundworms, heartworms and other internal parasites from getting a toehold in your pet’s gut and causing irritation or disease.

Other preventive tips. Keep ear problems at bay by checking frequently for redness or foul odors and noticing if your pet frequently scratches at ears or shakes his head. Ward off skin problems by brushing the coat to remove dirt, distribute skin oils, and remove dead hair so it doesn’t mat and tangle; thoroughly rinsing the coat with fresh water after swimming in pools, lakes or saltwater; and cleaning and drying loose skin folds regularly to prevent bacteria and yeast growth.

Q&A

Cat swings from

nice to naughty

Q: Our cat seems to have two personalities. She is an 8-year-old rescue that we have had for a few months. She can be sweet when she wants to sit by us or when she jumps up on our bed, but more often, she is on the defensive. When we bend down to pet her, she usually tries to bite. Sometimes she reaches out for passing legs. No one dares pick her up. Any suggestions? Do you think it had something to do with her previous life?

A: Cats are more comfortable when they are the ones doing the “choosing” when it comes to initiating closeness or interaction with a person, especially if they’re fearful. Acting out when being petted could be a defensive response caused by fear. Swatting at legs as people walk by could be a type of predatory play behavior.

A consultation with a Fear Free-certified veterinarian, veterinary behaviorist or certified applied animal behaviorist who can see your cat’s behavior in person could help you get a better picture of why your cat acts the way she does or uncover underlying health issues that may be contributing to her behavior.

What animals learn during early life can forever impact their adult personalities and comfort level with humans and their environment. Animals can still learn throughout life, but their basic resilience in the face of stress is formed early. That said, you can do some training exercises to build your relationship, communication and her confidence. One is to turn petting into a positive by pairing the reach of your hand with a desirable reward, such as a favorite treat or toy. A skilled behaviorist or trainer can offer other suggestions. -- Mikkel Becker

Dogs’ noses aid

disease detection

-- Could your doctor have a canine assistant one day? Bio-detection dogs sniff out the scent of diseases such as cancer by checking urine or fecal samples, breath odor or skin swabs. They can be a “second opinion” for cancers that are sometimes difficult to diagnose, such as prostate cancer. Studies are also examining their ability to identify the presence of malaria and Parkinson’s disease. Other canine medical aides are trained to notice minute changes in a person’s odor, alerting them to impending seizures or abnormal blood sugar or hormone levels. These medical-alert dogs primarily work with people who have seizure disorders or diabetes, but some have been trained to help people with Addison’s disease and severe food allergies.

-- Scammers have invaded pet adoptions. Be cautious when adopting through online rescue groups or individual placements. If the organization or person placing the pet asks you to wire money or send a pre-paid debit or gift card to cover the cost of shipping the pet to you, it’s likely a fraudulent transaction. Once they receive payment, you may be hit up for more fees to cover nonexistent emergency vet visits or the cost of a crate or pet health insurance. Or they may claim the animal has been shipped, but the pet never arrives. For more information, check BBB Scam Tracker (bbb.org/scamtracker/us) and IPATA’s (International Pet and Animal Transportation Association) page on pet scams (ipata.org/current-pet-scams).

-- We know Pomeranians as toy breeds, but in the 19th century, they were much larger dogs, weighing 20 to 30 pounds before being bred down in size. Today, they typically weigh 3 to 7 pounds, but oversize ones are not unusual and can be a good choice for families. Poms come in many colors and patterns, including orange, white, black, chocolate, sable, cream, black and tan, brindle, and blue. -- Kim Campbell Thornton
