Any one had any problems with Metacam? Its a painkiller, wich IS licensed in this country for cats; in US (I've been told) apparently it used only for dogs..... It seems simetimes to cause renal failure or incontinence in cats? I've got a cat - which needs a painkiller at the moment and been prescribed Metacam. I asked a Vet to change it to any other painkiller. The answer was: 1 - " cats have sencitive kidneys anyway....." (!?!?!?love that one) 2 - "this painkiller licensed in this Country" 3 - "the only other one we have - needs to be injected therefore cat have to be hospitalised".... Any thought? ideas? advise? Thank you.
