DEAR DR. FOX: Why is your book "Not Fit for a Dog" not in the library system in Denver and surrounding area, nor in Prospector materials databases and interlibrary loan? -- A.L., Denver

DEAR A.L.: Thanks for your email on a very important issue for authors -- not about making money, for me at least, but all about getting the message out to help improve the health and well-being of our animal companions as well as those who love and care for them.

There are many reasons why libraries don't carry certain titles (mine being mainly in the nonfiction area, although I have received literary awards for some of my children's fiction books). These reasons range from increasingly limited budgets to assumed lack of public readership interest. In some backward areas, it's even a case of censorship.

I know that many of my books have been pilloried by the animal industry complex. One sector of this complex, which my book "Not Fit for a Dog!: The Truth About Manufactured Cat & Dog Food," co-authored with two other veterinarians, criticizes and urges to improve pet food quality and safety, has much money to use for lobbying and political influence. This sector even put my job on the line, complaining about me to one particular CEO of the Humane Society of the United States in the late 1990s when I began investigating what goes into pet foods.

Some people who like a particular book and want to share it with others will donate it to the library. If you prefer, you could ask the librarian to pull up the book title on the Internet and see if he or she would consider carrying it. Then take it from there.

DEAR DR.FOX: Thank you so much for answering. I finally did find your book in a different library system. I'll be persistent with my own library to buy the book. There's also an excerpt of "Not Fit for a Dog" on the library website that condenses your book and tells a lot of important information. I've had a huge vendetta with Purina, whose name I can barely get out, because growing up I had a black Lab on Purina who had kidney disease by age 6. Photos of the dog at 5 and 6 years look like he's only half alive. He lived to be 7.

Maybe people can get educated. Many have blind faith in advertisements that companies take advantage of. Additionally, some people may feel that dogs shouldn't get expensive food -- it is part of our Puritan ethic against frivolousness. I can't thank you enough for writing. I'm sure my county library will buy your book. Thank you for your bravery as the harassment I'm sure has been immense. -- A.L., Denver

SOCIALLY ISOLATED PARROTS AGE FASTER THAN THOSE IN GROUPS

If you feel sad or mad seeing "pet" parrots living alone, isolated from their own kind, then you are right on the mark! Telomeres act as a protective cap on the ends of chromosomes and have been likened to the binding on the ends of shoelaces that prevent shredding. These telomeres degrade with age, and a team of Austrian veterinarians and others has provided the first evidence that social isolation affects telomere length.

African gray parrots bred in captivity and raised alone seemed to age faster because they had shorter telomeres compared to those raised in pairs or groups. This supports the investigators' hypothesis that telomeres provide a marker indicating exposure to chronic stress and may be a better indicator of measuring stress in nonhuman animals than measuring corticosteroid stress hormone levels.

These findings support my long-held contention that the common practice of keeping various highly social species as solitary pets, which often makes them abnormally attached to humans, is both harmful and ethically questionable. For a penetrating critique of the animal industry complex and of currently condoned ways of keeping animals for pleasure and profit, see "Slaves of Our Affection: The Myth of the Happy Pet," by veterinarian Dr. Charles Danten. The author tells me that he was inspired by my earlier book, "Inhumane Society: The American Way of Exploiting Animals."

DEAR DR. FOX: I'm having a problem with my barn cat. This cat, Samson, moved into my barn last spring. I had him neutered, and he has his shots.

Samson became so aggressive with my other barn cats that I moved them to my house. Samson now attacks me when I walk away from the barn. I thought that he needed more attention, but that only seems to make the situation worse. Sometimes I pull a string so he attacks it instead. Today he attacked me with teeth and nails, and I had a difficult time getting him to stop. What do I do? -- S.S., Potomac, Maryland

DEAR S.S.: I understand why you had to move your other cats indoors after this domineering interloper took over and became such a bully. This must have been a stressful adjustment for them as well as you.

Changing Samson's name to Sammy won't make him more of a gentleman, just as neutering a cat later in life won't erase domineering and aggressive behavior patterns and some aspects of sexual behavior. Neutering before sexual maturity and experience does make a big difference, according to early behavioral research by the late Dr. Lester Aronson, whose research on cat sexual behavior was extremely controversial from an animal welfare and ethics perspective.

Many cats play ambush games and bat at your legs as you are walking by. This is their invitation to play and often comes from a life of boredom, which, to some degree, can be alleviated by playing chase and other interactive games. Samson's behavior is in another category since he is showing uninhibited attack or predation behavior toward you.

I would say goodbye to Samson for the greater good of your barn cat colony and your own peace of mind -- and health. Cat bites can mean hospitalization for blood poisoning (Pasteurella bacterial sepsis), and cat-scratch fever can develop from infected claws, with painful lymph node swelling misdiagnosed in more than one instance by human doctors unfamiliar with zoonotic diseases (animal-to-human transmitted infections) as lymphatic cancer!

An expert feline behavioral therapist might rehabilitate Samson once any possible underlying disease is ruled out, notably hyperthyroidism, which can make some cats more aggressive.

DEAR DR. FOX: Four weeks ago, I added a new member to my family: a 9-week-old rough-coat collie.

He gets 1/2 cup of dry dog food in the morning and again in the evening. The problem is that he does not chew his food, he inhales it -- it is gone in a few seconds. I have gone online, called the vet, have had an in-home instructor, but nothing helps. I have a divider in his food bowl, but it doesn't work. I put his food in a ball with a hole in the side that drops it out a piece at a time.

I am aware collies are prone to bloat, so I'm trying to fix this problem now. Any advice would be greatly appreciated. -- C.C., Springfield, Missouri

DEAR C.C.: I urge you to read up about proper puppy care and feeding, because two half-cups of dry dog food (and you do not indicate what brand and if it is formulated for puppies) is not enough. He most likely "inhales" his food because he is ravenous.

He should be fed at least four small meals daily. Give him 1/2 cup of dry, canned or home-prepared food at each meal. He needs high-quality protein and fat, with balanced calcium and other mineral and vitamin supplements. Be sure that a stool sample is checked for worms, which often infest pups and rob the animal of essential nutrients.

DEAR DR. FOX: I would like to get a small adult dog. I am handicapped and use a walker to walk, and I live in an apartment. I hope to be able to train the dog to go to the bathroom on a paper pad.

Some members of my family insist that I should not get a dog. They think that I will not be able to care for a dog because I will not be able to take the dog outside in the winter for walks (I live in northern Minnesota). I feel that a dog will be fine because I have plenty of room in my apartment to exercise and play games. Is it OK to have a dog in these circumstances? I would really appreciate your advice. -- J.C., Duluth, Minnesota

DEAR J.C.: Putting the best interests of the dog before yours, ask yourself why you want a dog? If it is animal companionship, adopt a cat if you are not allergic. Cats do not need to go outdoors, are 95 percent easier to train to evacuate indoors in a litter box and with all the interactive toys available, you can engage in stimulating games with the cat from the sofa or wheelchair. Dogs need to get out and run around, even in winter.

While you consider the best animal companion for you, think adoption first; also, consider getting two cats. Two cats will care for each other and give you hours of entertainment and devotion.

DEAR DR. FOX: When we decided to get a cat 10 years ago, I thought getting a couple of littermates would work well. They got along during the first couple of years, often sleeping together and grooming each other. As they matured, though, they seemed to grow more competitive for our attention. They seem to tolerate each other for the most part, but they often growl and hiss when one enters the territory of the other when one of us is around.

It seems like our tabby considers me to be her property to be defended when I'm in one part of the house, and our longhair considers me hers in another part of the house. They stiffen when I try to pet one if the other is around. If only one is on my bed, they welcome affection. If both are on my bed, they are very stiff, and they don't move. They show some of this behavior with my son, whom they both consider the most wonderful human, but they are both very attached to me, too.

The funny thing is, they don't seem to be jealous of each other when I have them outside on a leash. I wonder if they would have been better off as single pets. Their behavior is interesting and often annoying, like having a couple of your kids dislike and fight with each other.

I enjoy reading you column and my girls' diets are better because of it. -- D.B., Fargo, North Dakota

DEAR D.B.: Your cats' behavior will be familiar with many cat caregivers who have two or more cats. This kind of behavior is typically "cattish" in that they assert social dominance via the places in the home -- a lap, particular chair or windowsill -- that they prefer to occupy. This behavior keeps them apart and prevents conflict: "This place is mine. Keep away, and I will respect your place."

To avoid conflicts, as when one cat is on your lap or sitting beside you, invite the other over to be groomed on the floor, and get down to do this. Groom both of the cats at the same time. You may then set up a neutral territory or conflict-free zone on the floor in the middle of your living room. Our two cats will often engage in mutual grooming, which is a prelude to play-fighting and chasing. This often ends with one being rougher than the other and they part for a while, going to their favorite personal places to lie down.

DEAR DR. FOX: I have a 3-year-old standard schnauzer. She is absolutely wonderful now, but was a real handful from 10 weeks until about 2 1/2 years. We are getting along well now -- except for the sneeze thing.

Ever since I have had her, if I sneeze, she attacks me, tries to knock me down, growls and barks at me. I have tried everything -- telling her it is OK, etc. Barking back at her helped the most.

Do you have any idea why she does this? Maybe the noise it makes? The other thing she does is stare at me a lot. It makes me wonder if she knows something bad about me, like I have cancer or something. She is the smartest dog I have ever had, but the staring is beginning to make me a little nervous.

We are very close; we do everything together, and I love her so much and believe she feels the same about me. Thank you for your answers to these questions. -- B.B., Washington, D.C.

DEAR B.B.: Your best solution is called "flooding" or "total immersion": Set up a tape recorder and fake some sneezes for as long as you can, then play the tape back for your dog at a safe distance away from you for a few days every three or four hours. This should desensitize her very quickly.

Alternatively, when you are just about to sneeze, squeeze a squeaky toy for her, and throw it to her. This is called "redirecting behavior," and it is a recognized conditioning technique for a variety of canine behavioral problems.

Her staring at you may not indicate that you may have cancer. Here, you may wish to look at your own anxiety state, and reconsider her stare as simply wanting your attention, perhaps to play, be groomed or taken outside for a walk or to relieve herself.
