Aww, poor Dragan, I do hope it is just a mix of everything adn that he is OK soon.
Mark, painkillers are funny things in cats, my vet said there are very few that have been effective, and now Metacam is the only licenced product, so it is what vets should be prescribing. Things like Rimadyl which used to be used can only be used if hte vet puts a good case forward for using it - there can be serious side effects with that too, and I dont know if it is an NSAID, but if you search for it on here, I think Lynn might have posted the data sheet.
