My baby Eddie is 8 years old......I just brought him home from the Vet (humane Society clinic) last week after he blocked........He was great for a week now, he is hiding under the covers on the bed all day and all night......shaking his ears constantly..........He is on his new food and is doing well, using the litter box, drinking water but I am wondering if maybe he contracted ear mites while at the Vet......he was there for a week......he is a strictly indoor cat, no other animals.......any advice I can get I would appreciate........thank you
