Cat is a blue-purple cat, and the best friend to Peg. He loves circles (but not as much as The Pig loves triangles) and accompanies Peg on her adventures. Cat often inspires Peg to realize a solution to a problem without being aware of it himself. He helps to calm Peg when she "totally freaks out". He was inspired by Jennifer Oxley's pet cat. Voiced by Dwayne Hill. He also is quite clumsy and likes to eat (even foods that most cats wouldn't eat). He knows how to count but doesn't know as much math as Peg.
Cat has indigo fur. He has two gray eyes with black pupils, a gray nose and mouth, an indigo and gray tail, indigo ears, and indigo paws.
