The group is headed by Riff-Raff, a tan, short, tough, streetwise alley cat. Riff-Raff is a suave cat who fancies himself incredibly debonair. He often has get-famous and/or get-rich-quick schemes, which form the basis of many of the episodes. He is always shown dressed with a blue scarf and a sideways cap.Hector
Hector, a brown and beige cat who speaks with a New Jersey accent, is sometimes depicted as feeling that he should be the head of the group, and becomes so on some occasions, such as in the episode "Hector's Takeover". Riff-Raff and Hector's conflicts form the basis of a number of episodes. He is always seen wearing a tie and a headband.Wordsworth
Wordsworth, named after poet William Wordsworth, is a light-gray cat who always speaks in rhyme, and wears roller skates, yellow headphones, and sunglasses.Mungo
Mungo is a large, dim-witted gray cat who acts as a lackey for Riff-Raff. Mungo is often seen wearing a red shirt with a red winter hat. Though unintelligent, Mungo has astounding strength and fighting prowess. Mungo is a "gentle giant" and lighthearted in personality.Cleo

She is a cream-colored cat with long blonde hair. Her fur resembles a leotard and she wears a pair of pink legwarmers. In the flashback episode "Christmas Memories", it is revealed that Cleo is, in fact, one of the Catillac Cats herself, even going as far as to indicate that she coined the name. On more than one occasion, Riff-Raff ends up "two-timing" Cleo with another female cat.
