Odd question, but when my puppy had an allergic reaction the vet suggested piriton tablets. So I'm guessing it's similar?
My cat has constantly got a snotty nose and scratchy throat over the summer. Last year the vet suggested FHV and says he will have flare ups, but we got through winter fine and it's only since spring/summer started. He's really feeling sorry for himself and can't even meow. So I'm thinking of trialling him with some piriton in case it could be hay fever? He is shedding lots too.
