Like the rest of the Kitten Catastrophe Crew, Cat Chase was introduced as the "evil twin" of the PAW Patrol.
Cat Chase is shown to be the cruelest and most mischievous kitten, supposedly aside Cat Rocky, on the team. He is typically Mayor Humdinger's top pick for schemes. However, he's not always loyal to Mayor Humdinger and has had a history of ditching him when the going gets tough.
Cat Chase is a Cymric cat with brown fur, a tan face, paws, and tail tip, with a brown stripe going down to his black nose and brown eyes. He wears a blue vest with yellow trim, and a black collar with a blue Kitten Catastrophe Crew tag.
