My Pet World: We don't know for sure if pets 'grieve' the way we do

Apparently, you've ruled out flea allergies. Still, a pet doesn't need to be infested with these pests to develop a severe reaction.

The most likely possibilities for your dog's problem are food allergies or environmental allergies. You mention that you tried to change the dog's diet, but it's necessary to transition to a specific single-protein prescription diet or homemade diet (one specifically recommended by your veterinarian). Those are the only choices for a reliable food trial, and your dog must remain on the new diet for several months, without a scrap of table food or unapproved dog treat. Your veterinarian should oversee the food trial.

If you did go through a proper food trial, then environmental allergy seems the most likely culprit. Since your veterinarian is unsure about the next steps, it might be best to request a referral to a veterinary dermatologist.

Q: A year ago, my 7-year-old cat was diagnosed with kidney failure. Now, my 3-year-old Maine Coon has been diagnosed with the same problem. My veterinarian said his blood count is low and he's been receiving a steroid pill for that. I'm 66 and have had cats my entire life. Is kidney disease in cats something new? What might cause kidney failure in such a young cat? -- S.P., Umatilla, FL

A: Kidney disease is an exceedingly common problem among older cats. There's much in your question which is confusing, as feline veterinarian Dr. Susan Little, of Ottawa, Ontario, Canada notes. "Kidney failure is end-stage disease, kidney insufficiency or kidney disease is perhaps more likely your cats' problem, at least your older cat," she says.

As for the younger cat, Little says, "While we do see kidney disease in cats as young as 6 or 7 years, it's very unusual to see kidney insufficiency in a cat who's only 3 years old. As for steroids, cats can withstand their long-term use, but only with careful monitoring. Even in cats, steroids are not without possible side effects. Of course, cats should only be given steroids when warranted, and while it may be appropriate for this cat, the (reader's) question doesn't offer (a full explanation of what's going on).

Little, editor of the textbook "The Cat: Clinical Medicine and Management" (Elsevier, St. Louis, MO, 2012; $151), adds, "There needs to be clarification and also an explanation about what's going on with your younger cat. In this instance, I'd suggest an exam by a feline veterinarian." Your veterinarian can offer a referral or you can check the American Association of Feline Practitioners: www.catvets.com.

Q: Our cat, June, sits at the window and meows at birds. Why does she do this? -- S.C., Macon, GA

A: When you see something exciting going on outside your window, you might say 'Hey, look at that!' That's exactly what your cat is telling you. Certainly, watching butterflies, birds and moths fly by is exciting entertainment if you happen to be a cat.
