Raw foods are terribly dangerous for FIV cats! Whatever you describe as natural is "once natural" and domesticated felines have evolved systems. In nature, FIV cats would simply die off early. They CANNOT combat bacteria that might be in these foods. It's really a shame that people would try this on your advice and endanger their animal. You can make healthful food for your cats; you don't have to add fillers like rice but you should add vitamins, especially iron. If your cat also has kidney problems, that makes it complicated. But, as a person who has had 4 cats living to be over 20 years old, I'm sticking with what I know. NO raw foods to FIV cats.
