Here's another Pepper update. I bought him some new food today called Felidae. It was one of the foods on the list that I received from the vet. This food has even helped cats with the feline leukemia virus. It also doesn't have any ingredients in it that he's allergic too and it costs just a little bit more than the food I've been feeding him. Here's the website if any one is interested www.canidae.com. I mixed it with the old food and Pepper really seemed to like it. The problem is that he threw up again this evening. This time it was a large amount of food. Tomorrow I'm going to try to feed him only small amounts of food and see how it goes. My roommate is on disability so she said that she can help me feed the cats during the day. I sure hope that this will work because I don't know what else to do.
