This is an unnamed cat that is a recurring character that often appears in episodes, who always has a minor role.
The cat is gray with darker gray stripes on its head, back, legs, and tail. It has green eyes. It has 3 stripes on its head similar to Catboy. It is unknown currently if this cat has a name, and whether it is a stray or someone's pet. It is safe to assume it is a feral cat, for it is always seen outside during the show.
