Here's another update on Pepper. I finally received the results from his food allergy test. It says that he's most allergic to beef,milk,soybeans,corn,wheat,sugar beet,carrot,peanut,yeast, and potato. When the vet receives a hard copy of the test results he'll also receive a list of cat foods that would be good for him to eat. The problem is that I free feed my cats so they all need to be on the same type of food. Pepper's been doing much better but he still sneezes from time to time. Another thing that I might need to change is their litter. I've been using a wheat based litter and the vet said that if he inhales this or eats it then it can also affect his allergies.
