Cats teeth cleaned? Wut the hell is this mess? Maybe you aren't feeding them the right stuff. You should be feeding them top shelf crunchy food and on occasion wet food. The crunchy does mechanical cleaning (not chemical) and should be sufficient. I've had catz for 30 yrs and my first kitty had bad teeth and the vet said it's because she was eating too much wet food, which she was. Ever since then it's been top shelf (ideally top shelf from a pet store and not that shit from the grocery store) crunchy and haven't had any problems since.
