Does anyone know if tuna is a common allergen in cats?  Since
Shamrocks last steroid shot 2 months ago, his fur has grown back .  He
used to only go about a month before the itching started again so
badly that he would bite himself raw.  Today I noticed that he is
biting his tail raw almost like he's trying to chew it off and it
wasn't like that yesterday.  He hadn't had any tuna at all in a while
due to some of the posts here; he used to only get some as treats
occasionally but I've cut those treats out altogether.  I recently
bought Petreet which has a tuna and rice (can says 50% tuna) and he
scarfs it down.  I was happy he likes two of the Petreet flavors, the
tuna and rice and the chicken and rice because the ingredient list
(hold your flames about ingredients, guys) is very small and it has
good meat content and no corn or wheat grains.   I started getting
worried about the high tuna content.  Then today with the severe
itching and biting, there may be a link here.  I'm going to get the
feral into the vet tomorrow so I'll see if she can see Shamrock too
but if tuna is a common allergen maybe I've found it finally??  I read
on a vet site that among the common feline allergies that inhalant is
the most common; that came above flea allergy which I find hard to
believe.  Food allergy is suppose to be rare but happens, obviously.
