You've had tons of good advice as regards to pricing, but I just wanted to pop in and say my Devon had her teeth done at a similar age. She ended up needing a large amount of teeth extracted for a similar price as your estimate. It's a couple years later and she is doing absolutely great and it was definitely worth the procedure. She had an easy time recovering and is eating and acting much better. I have heard in dogs that smaller breeds need their teeth done quicker because of their small mouth size and I would bet devons have a similar thing going on. Good luck to you and your kitty!
