I struggle getting Atopica liquid into my cat so my vet game me the capsules for dogs, but I read on the package it only meant to be used for dogs. Is it safe for my cat?
Yes it is safe, it's the exact same drug only difference is cats have liquid form whereas dogs have capsules/tablets.
People tend to find it easier to give liquids vs pills to cats.
