Hi mspepper and welcome to Pet Talk. I've had 2 of my 4 cats teeth cleaned before but they weren't overweight. They also had bloodwork done to make sure that everything was okay before putting them under with anesthesia. They never had any problems. I'm sure that Pepper will do just fine. I know it's hard not to worry about your baby but try not to stress out too much.

Prayers and positive thoughts are being sent your way for a smooth and successful teeth cleaning. Please keep us posted.
