i just adopted my 4 month old kitten and he has been sneezing and has a runny nose. the shelter told me that he had had an upper respiratory infection previously, but that it should be all cleared up. i guess its not. is there any immediate danger? i mean do i have to rush to the vet first thing and will this be cleared up? i heard these kind of things may never go away and i dont wany my poor kitten to always have a wheeze. anything i can do in the meantime to make him comfortable? hes warm and such, but i havent seen him eat. i dont think he can smell his food.
