Some romance between Shriek and Dog, but Dog doesn't get it.

A character named Mindy Wonderful wears a midriff baring tank top.

General slapstick violence, nothing too intense.

In Season 2 Episode 11, Cat is dressed as a German by wearing a lederhosen and holds out a frothy beverage, it's assumed to be beer. This is very brief.

In the episode "Teeth for Two", Cat is seen turning himself inside-out and comes out of Dog's mouth to brush his teeth while he's asleep. The scene is very graphic and will likely frighten young viewers.
