DEAR DR. FOX: I have a 2-year-old neutered male tabby cat who has a bad yowling problem, and I don't know how to fix it.

I feed him twice daily, as that was the way the people fed him before I got him. I have had him for a year. I feed him 1/2 cup dry food (Purina One) morning and night. If I put the food out at once, he eats it all. Then, when evening comes, he thinks he needs more. He will sometimes throw up because he has eaten too much.

He yowls loudly if I don't feed him the minute I step out of bed and continues until I feed him. He does the same thing at about 9 p.m., though I try to make him wait until 10.

He is a very lovable cat, and he loves to sit on my lap and cuddle. He does not cry except when he wants food.

I would like to know how to break him of the yowling problem or if I just have to deal with it. I would like to be able to put all the food out at once, as sometimes I go away for a few days, and I have to have someone come feed him. -- S.M., Maryland Heights, Mo.

DEAR S.M.: I think your main problem is your feeding schedule, but you might not be feeding him enough. He cries because he is ravenous! Feeding twice a day is OK for dogs, but four to six times a day is better for cats. Feed him smaller portions, and weigh him to check if you are giving him too much or too little.

Some people complain because their cats never "speak." My first cat, a Siamese named Igor, would yowl for attention and when he was hungry. My solution was to talk back, play with him and take him for walks in a harness on a leash.

Your cat may be much happier with a companion cat, so consider a healthy, young neutered male or spayed female from your local shelter. Check my website, www.twobitdog.com/DrFox, for the best steps to take to introduce a new cat -- and for some better brands of cat food.

DEAR DR. FOX: I have two small dogs. I feed them dry food (Solid Gold Just a Wee Bit) in the morning and canned food (Blue Buffalo) in the evening. I would rather make their food for the evening feeding.

Can you please provide a recipe and advise me of any supplements they should be getting. They are my babies, and I want to do good for them. They love carrots and apples, so I try to provide these often. -- A.L., Brick, N.J.

DEAR A.L.: I receive many requests for my basic dog and cat food recipes. Many of my readers do not have access to a computer and my website, so I have published the recipes in my book, "Not Fit for a Dog: The Truth About Manufactured Cat and Dog Food." The book has details about supplements and the ingredients in many prepared pet foods owners should avoid.

As a treat, here is my basic dog food recipe:

1 pound lean hamburger, ground lamb or mutton; one whole chicken; or half a small turkey (all raw)

2 cups uncooked whole-grain rice (or barley, rolled oats or pasta noodles)

Pinch of salt

1 tablespoon vegetable oil (or flaxseed oil* or safflower oil)

1 tablespoon organic butter

1 tablespoon wheat germ

1 tablespoon apple cider vinegar

1 teaspoon brewer's yeast

1 tablespoon calcium carbonate, calcium citrate, lactate or human-grade bone meal

*If you're using flaxseed oil, add it after the cooked food has cooled to room temperature.

Combine all the above ingredients. Add enough water to cover ingredients. Simmer, stir and add more water as needed until cooked. Debone the chicken parts, but do not feed your dog the cooked bones since they can splinter and cause internal injury. While the stew is still very hot, mix in a cup of raw, grated carrots, sweet potatoes or yams. The recipe should be thick enough to be molded into patties -- you can add oat bran, rice or buckwheat flour to help thicken.

For a 30-pound dog, serve 1 cup of this recipe twice daily. Freeze the rest. You can even serve the patties frozen so your dog can gnaw on them in hot weather.

For dogs less than 30 pounds and for overweight and less-active dogs, use only 1 cup of uncooked rice in the recipe.

Transition your dog onto this new diet gradually. Mix increasing amounts of your dog's new food with decreasing amounts of the old food over a seven-day period to enable adaptation and avoid possible digestive upset. For variation, you can use cottage cheese, well-cooked lentils, garbanzo beans, lima beans or a dozen organic eggs as meat alternatives. (Note: Some dogs are allergic or hypersensitive to some foods, especially soy, beef, eggs, wheat and dairy products.)

Don't forget: Lightly cooked calf and beef liver, heart and kidneys are good sources of animal protein and other essential nutrients. All pet food ingredients, ideally, should be organically certified.

Give your dog a daily multivitamin and mutimineral supplement like Pfizer's Pet Tabs. You can also give your dog half of a human one-a-day supplement equivalent crushed up in the food.

DEAR DR. FOX: Two years ago, I adopted a beautiful male snowshoe cat from the animal shelter. He is very sweet, natural and content to be with me. But in all this time, I have never heard or felt him purr. I've had cats my entire life, and I have never known one not to be able to purr.

Do you have any explanation for this? He's 4 years old. -- P.G., Virginia Beach, Va.

DEAR P.G.: There is no scientific answer to your question, only educated guesses about genetics and individual differences. Many readers will attest to the fact that their cats never purr or meow. Some silent cats become vocal after a vocal cat in the home passes on.

Fear is a significant inhibitor of purring. The word "copycat" is appropriate -- cats learn from one another, so being separated from other cats at a young age might account for some cats' vocal sounds not being triggered.

Try brushing your cat, and learn some massage therapy to help induce deep relaxation, which I've detailed in my book, "The Healing Touch for Cats." Hearing harp music or Gregorian chants can make cats relax and might get yours into a purring mood.

While cats may purr to relax and convey friendly intentions, one scientific theory holds that the vocal vibrations may influence bone density and help prevent osteoporosis. My view is that since purring may involve circular breathing to create an almost-continuous sound -- a trick some musicians employ, as I do when playing a didgeridoo -- the cats may be inducing a meditative or altered state of consciousness.

DEAR DR. FOX: We adopted a wonderful 2-year-old shelter dog last summer, but he has one bad habit we need your advice on: He eats his stool. We've been told it's not uncommon, won't harm him and he'll probably outgrow it.

But the problem is worse because we have three other dogs, and he wants theirs too. Our vet gave us For-Bid to add to all the dogs' food, but it didn't work. We tried Stool-No! tablets, pepper on the piles and scolding and shaking coins in a can when we catch him in the act. We have to go into the yard with him and follow him around now.

Out in the cold last night, walking around with our flashlight, we started wondering what Dr. Fox would do. Since it's not harmful, should we just relax, let him out unsupervised and try to not think about what is happening?

We walk our dogs every morning until they go, and we pick that up, but the rest of the time requires watching him closely. We used to be able to let our dogs in and out whenever they wanted.

Also, he poops about four times a day, which seems high. Is there a food or diet you recommend that might help with that? -- B.B., St. Louis

DEAR B.B.: I receive many letters from dog owners who, like you, have a stool-eating (coprophagic) dog. Go to my website, www.twobitdog.com/DrFox, and check the archives for various answers and solutions to treating this problem.

This obnoxious activity has psychological and physical causes. The former is linked with dogs being caged or crated for long periods of time and, out of boredom or desire to keep their "den" clean, they engage in coprophagy. The habit can persist even after dogs are provided normal living spaces and outdoor activity -- which may be why he cleans up the other dogs' poop. Try using a muzzle when he's out in the yard with your other dogs; it may break his habit after a few weeks.

Possible physical reasons include dietary or digestive issues. Many dogs show improvement when given brewer's yeast (1 teaspoon per 30 pounds of body weight) in their food, plus 1 tablespoon of probiotic-rich yogurt or kefir. Many dog foods are high in cereals and fiber, which can mean large-volume feces and frequent evacuations, so you may want to transition all your dogs to canned food or low-fiber dry food -- or you can try my home-prepared recipe.

DEAR DR. FOX: I have a 5-year-old pug. He has several black spots that look like warts on his stomach.

The veterinarian I took him to retired, so a young vet has taken over. The previous vet put him on steroids, but the new vet said she could remove them with surgery. She tells me the warts are caused by a virus.

What could be causing these growths? What options do I have besides surgery? Can I be infected by this virus? -- D.J.W., Uniontown, Pa.

DEAR D.J.W.: Yes, your dog's warts are caused by a virus. But since it's different from the viruses that cause warts in humans, you have nothing to worry about. You can't get an infection from handling your dog.

I am glad that the veterinarian who prescribed steroids has been replaced. Steroids could make the problem worse and have other side effects.

Try "painting" the warts two to three times a day with apple cider vinegar -- you'll have to stop your dog from licking it off for about 30 minutes. If you see no improvement in a few weeks, I would consider surgery. Have the surgery done soon if any of the warts seem infected or ulcerated and are causing your dog discomfort.

Several other home remedies for warts are in the archives section on my website, www.twobitdog.com/DrFox. Some readers have found success by applying vitamin E squeezed out of the gelatin capsules.

DEAR DR. FOX: My ferret, Sparky, is 6 years old, and he has halitosis. When I am playing with him, my hands sometimes smell bad from his saliva. Sometimes he drools a lot.

He won't chew bones to keep his teeth clean. What do you advise? -- S.K.L., Springfield, Mo.

DEAR S.K.L.: Ferrets, especially older ones like yours, are prone to developing gingivitis, an inflammation and infection of the gums; tartar, especially on the upper back teeth; and periodontal disease.

Have your ferret examined by a veterinarian, especially because any of these dental problems can lead to complications, including heart, kidney and pancreatic diseases due to bacteria, toxins and inflammatory substances that build up in the ferret's diseased oral cavity.

After professional dental care, maintain oral hygiene by providing your ferret with thin strips of raw beef or slices of raw turkey gizzard to chew. Applying PetzLife Oral Care gel or spray will help keep the teeth free of tartar and maintain healthy gums.

DEAR DR. FOX: I had a cat named Samantha who lived to be 22 years old. The vet said he could have lived until he was 23 years old. (He had only nine months to go.) I had to have him put to sleep as he had throat cancer. The vet said he lived a good life and was well taken care of.

He ate all types of dry and moist cat food, plus tuna, chicken, turkey, salmon, ham, sweet potatoes and flaxseed oil. He was an indoor cat who never got fleas and who walked on a leash like a puppy. He was more like a kid than a cat.

He slept in my arms like a baby at night. He would use his litter box one time, then come to me and meow to let me know he wanted the litter changed. When company would come, he would go down the steps to greet them. (I live in an upstairs apartment.) He loved to go for walks, and he loved to have his hair combed like a person.

I could write more, but I should stop. I'm thinking about writing a book about that cat. -- N.K., Romney, W.Va.

DEAR N.K.: Cat owners and lovers will enjoy your brief story about life with Samantha.

Some of the ways to help cats enjoy a long and healthy life are confirmed in your letter -- love and understanding, a nutritious diet, and keeping your cat indoors unless walking on a leash.

Flaxseed oil is good for dogs and most humans, but it is inadequate for cats, who need fish oil as a source of essential fatty acids.

My book "Supercat" details other ways to enrich the lives of indoor cats and includes interactive games that can be applied to test cats' IQs. Some cats are brighter than others; they have greater insight, reasoning, focus and dexterity.

I wish more people would have more than one cat. Adopting littermates or a mother and her kitten(s) is an easy way to have multiple cats. Check my website for details about introducing a new cat.
