Cornela,
The FDA has approved Metacam for cats, the use varies. If you can give me the dose you have been giving (and read the box for the mg/ml) I can tell you if it was above the recommended dose, but metacam is used with cats.
You need to remember as well that all animals/humans respond differently to medications. People can go into liver failure with simple Tylenol...so there is never a 100% guarantee with anything. I am sorry you are dealing with this. I have read of another case of a cat going into kidney failure but responded well to treatment.
Again, if you want to know if the actual dose is correct, please respond.

I just sent you a private message, but here is what I wrote...hope it helps!
I just wanted to you to know the dose was not too high. I think the vet gave a good drug, I use it often, and your cat's body reacted to it. I am sorry, as I am sure your vet is too. He needs to make sure he reports this to the company so that if there is a problem documented that they put more warnings to other vets.

Still okay...although drops are hard to measure...I still think it was in the dose range.
