Bubble Cat toothbrush

Bubble Cats love fish fruit. They eat fish fruit whenever they can. But they need to brush their teeth very well at the end of a fish fruit feast. To do this they use a special type of toothbrush that has lots of very tiny wheels.

How can a toothbrush with wheels work to clean teeth well? And what sort of brush might the Bubble Cats use to clean their fur, paws or tails?
