Thomas "Tom" Cat is a fictional character and one of the two titular main protagonists (the other being Jerry Mouse) in Metro-Goldwyn-Mayer's series of Tom and Jerry theatrical animated short films. Created by William Hanna and Joseph Barbera, he is a grey and white anthropomorphic domestic short haired mute Tuxedo cat who first appeared in the 1940 MGM animated short Puss Gets the Boot. The cat was known as "Jasper" during his debut in the short; however, beginning with his next appearance in The Midnight Snack he was known as "Tom" or "Thomas".
