I tried a long time ago with Storm and Sunny and they were okay with it. My other cats Sky and Cirrus would hate it though. Now I just feed them dry cat food that is supposed to help clean their teeth. Both Sunny and Storm have had their teeth cleaned before and I'm sure that my cats will need this done in the future.

I think it's easier to start this when their still kittens. Also some cats have better teeth than others no matter what you do.
