No, the vets didn't tell me it was an allergy. I'm just guessing since it's didn't bother him at all while he was at the vets. He is already getting teramycin for his eye, that's what my vet gave me when I took him in earlier for the eye problem. It just seems odd that when he is out of the house he is fine, but as soon as he's back in the house it bothers him again. I don't think it's stress related because he was stressed at the vet and it was fine, and even if he is a little stressed here it wouldn't be nearly as stressed as he would have been at the vets.
