Hi, I didn't read all of the replies in this thread but I wanted to share my experience with RIMADYL. I was given this for Snoot after he was neutered years ago. Snooty was neutered later in life, not as a baby so it was easy to realize something was going on. Snoot developed a very high fever and became extremely aggressive. Snoot doesn't have a mean bone in his body but the RIMADYL made him act like he was out of his mind crazy. I'm not even kidding here. He reminded me of what an animal would act like if they had rabbies. We couldn't touch him or go within a few feet or he charged at us to attack.
This started the day after surgery. At first he just seemed very cranky but he got worse by the evening. My vet's office was closed so I couldn't call and ask about the drug. I got online and went on the pfizer's website and looked up the drug and Snoot was definately having a reaction to it. I stopped giving it right away and he was back to normal by the following evening. Needless to say it's written in his charts, 'NO RIMADYL.'
After this I read a lot online about this drug. So many have had bad reactions and yes even death.

I know some are fine taking it but I personally will never, ever give any of my babies it since the terrible experience with Snoot.
