I have a 5 month old kitten that would get these lumps on her neck and they would eventually turn into open sores. Took her to the vet 3 times and finally on the 3 rd time the vet said that he sees those sores in cats that are stressed or have food allergies. He gave her a cortisone shot and said if it worked then I needed to check her diet. Sure enough the bumps and sores are gone. I feed her EVO canned 2-3 times a day and her kibble it Kirkland (the dark purple bag). So I am trying a elimination diet to see what the culprit is. I am in the process of switching her from kirkland to solid gold which is a grain free food. So am I on the right track? Or should I begin with eliminating certain proteins instead? BTW she also has a runnny eye and displays symptoms of a URI, but I was wondering if that to could also be from her food allergy? She's been treated for URI's and is fully vaccinated now. So any suggestions would be appreciated!
