What is the name of Minnie Mouse's pet cat?

Minnie Mouse’s pet cat is named Figaro.

Figaro is a black-and-white kitten who first appeared as Geppetto’s pet in Disney’s 1940 animated film Pinocchio. He is mischievous, expressive, and frequently irritated by Cleo, Geppetto’s goldfish. The character proved popular enough to continue beyond the feature film and later became associated with Minnie Mouse.

Figaro’s connection to Minnie developed in Disney shorts rather than through a detailed origin story onscreen. He first appeared with Minnie in First Aiders in 1944 and subsequently appeared in several cartoons with Minnie and Pluto. In that setting, Figaro functions as Minnie’s cat, while Pluto is Mickey’s pet dog and a frequent comic rival.

Cleo is an easy answer to confuse with Figaro because both characters belong to Pinocchio and live with Geppetto. Lucifer, another famous Disney cat, belongs to Cinderella, while Tibbs is associated with The Aristocats. Figaro therefore has two important Disney identities: Geppetto’s kitten in Pinocchio and Minnie Mouse’s pet in later cartoons.
