Aww, Tam, it is a shame I am going to the pub, or I could have had a chat with you, it is an awful situation to be in. IT sounds like they might have given something like Metacam as the anti-inflam, I know that can't be given with kidney issues, but agree totally with your reasoning. I have a suspicion they might last a couple of days, but the vet should have explained this to you. Can you speak to an emergency vet and ask them, although if you dont know the name it would be tricky. Did you get an itemised bill, that might have the name on it. Sorry for all the questions!!
