Adding my 2 cents on food for what it's worth...
I just lost my precious Morris on 9/22/05. He was 20 years old and maintained excellent health! Got most of his life I fed the regular Purina Cat Chow. I tried other types here and there (the one Purina came out with for inside cats, for example) but he preferred Cat Chow. Once a week or so I fed him wet Fancy Feast - which he regarded as a real treat!
Interestingly, when he was younger (like 4-5 years old) he developed some type of allergy or condition (I also owned dogs at the time) where he was licking his fur off. The vet said he likely had a food allergy and prescribed some kind of very expensive food that could only be purchased at the vet. Morris got WORSE!!
I was trying various foods by trial-and-error then and that's how I finally chose Purina Cat Chow which worked well for him and he ate until his dying day.
There is a book called It's a Cat's Life
by Anitra Frazier. In the book Ms. Frazier has 3 diets that she highly recommends - one completely homemade from meats, veggies and vitamins, one wet food with some vitamins added and a third from baby food with th vitmins added. I'm going to do a "trial run" with one of these for Kali and see how she does. I'll report back on this. Czari
