Someone in my family had once read that the certain kind of anesthesia that is used for dental procedures in cats can cause them to develop kidney problems. I had a 14 year old male cat a few years ago that had his teeth cleaned (actually they got me to do this as he was already having surgery for a tumor removal). Then six months later his health just plummeted.
Now I'm very paranoid to ever have my other kitty's teeth cleaned.

Has anyone else heard about this? My cat is 13 and a half years old and never had his teeth cleaned but eats fine, etc. I just don't know if it's worth taking a risk. He does have a stained, brown colored tooth, or actually the row on one side appears is more stained than the other. Could be he uses that side more.
Thanks for any thoughts on this, Lori
