I hope the vet visit will go smothly! I'm sure Sunny will enjoy getting his teeth cleaned - at least after. When Fister had it done, his bad breath dissapeared.

Getting Cirrus sedated is a good idea, I don't know the medicine he'll be getting, but it's always nice if it doesn't last so long. Lately, we found that 5 mg. Diazepam (equivalent to Valium) is all it takes to calm Fister down enough to lift him and get him in the box. If the vet finds it neccesary, he'll give him something while he's there.

Try to be as relaxed around them as you can before you go!

Best of luck!
