Have Cat Questions? Ask a Cat Vet Online.
Hello, this is Dr. Jess. I am sorry to hear about your kitty. It is possible that your kitty is having an adverse/allergy reaction to some ingredient in her food. You can try putting her on what is called a novel protein diet- you will have to cook for her initially- eventually you may be able to switch her back to a limited ingredient canned food. You can find recipes for diets at a website called balanceit.com, which is run by veterinary nutritionists. Here is a link:https://secure.balanceit.com/tools/ez2/result.php to diets for allergy issues- be sure to use a cat specific recipe. It can take up to 2 months of being on this diet to see a difference, so don't give up after just a week or two if you aren't seeing an improvement. During this time, your cat can have nothing else to eat- not a bite of the dog's food or another cats food or a treat- only this limited ingredient diet! Or you will be wasting your time and money! Here are some articles on food allergies for you as well: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=652
If after several months on the diet you don't see a difference, it is possible your cat has atopy (environmental allergies) and you may need allergy testing done.
