New cat food allergies? Need next steps...
I guess I'll be taking my boy to the vet, but would love to know what to expect.
History: Terigo is going to be 12 this spring. I NEVER bought designer cat food of any sort -- I just didn't know, and there was less information about the poor quality or substandard ingredients in so many "regular" brands.
Now I try to get at least a better-than-average brand. But over the past year, Terigo has had a horrible itching problem. So much so that he is all cut up and scabby from his own claws.
I have changed brands a couple of times but it isn't scientific, or at least I don't know all the right answers -- like, how long would it take for an allergy to manifest after changing food? Immediately? I have had him improve right after changing foods, only to get worse again before the bag is gone.
I battle fleas with the kitties too but his itching seems unconnected. It is no better right after a flea treatment, nor worse when it's time to re-apply the Frontline.
Why would it have started so late in this kitteh? Or are cat foods getting worse?
Will the vet actually run allergy testing, and can they test down to an ingredient?
