Tubby & Peanut's Mom: You should give it a try. The toothpaste and brush can be purchased at any pet store. My guys just love the stuff. Once they get the addiction going, they may just let you put your fingers or brush in their mouth. Maybe not. My last kitty (RB) would NEVER open her mouth. These two monsters let me do anything to them! Well, most anything. They even enjoy going to the VET. Go figure! They just like being touched! At any cost.
