Cats' diets are jacked up and anti-cat, just as ours are jacked up and anti-man. Grains and sugars are killers for both man and cat.
We need to get our cats on a better diet. I have a lot to learn on this topic, but here is some reading I am going to start working on (I'm just mentioning it; I have not read it so cannot recommend it):
Cat Nutrition.org Blog
Feline's Pride (cat food company)
Nature's Variety (cat food company)
Feline Future Cat Food Company
Raising Cats Naturally (book)
Your Cat: Simple New Secrets to a Longer, Stronger Life (book)
Are any of the above irrational in some way (anti-industry, anti-capitalism, anti-man, etc.)? If you find out, let me know please!!
Any other ideas? What can we do to keep our cats healthy by the standard of cats and carnivores?
Update (7-31-09, 5:05 PM CST): Yup. CatInfo.org has some good information, and I recommend reading it -- but the writer, the vet Dr. Lisa Pierson, has an anti-man streak. She says: "Not all that long ago (1980s) cats were going blind and dying from heart problems due to Man's arrogance. It was discovered in the late 1980s that cats are exquisitely sensitive to taurine deficiency and our cats were paying dearly for Man straying so far from nature in order to increase the profit margin of the pet food manufacturers."
Then, um, she goes on to "arrogantly" say what man, what reason, has found out about cat health and nutrition; she goes on to "arrogantly" make recommendations for how we, "man," should take care of our cats.
This idea of "the arrogance of man" is an old one, going back to the beginnings of Christianity, if not earlier. Did not Christianity preach against the "arrogance of the eyes" when Galileo and others developed the telescope and microscope?
Fact is, it was error and ignorance that "led to" the deaths, not "arrogance of man." This "arrogance of man," Mrs. Pierson needs to learn, is self-correcting and life-sustaining.
I'd say "If this be arrogance, make the most of it!"
