Overview
Thomas Jasper "Tom" Cat Sr. 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 British 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".
History
Tom and Jerry cartoons
His name, "Tom Cat", is based on "tomcat", a word which refers to male cats. He is usually mute and rarely heard speaking with the exception of a few cartoons (such as 1943's The Lonesome Mouse, 1944's The Zoot Cat, 1947's Part Time Pal, 1953's Puppy Tale and 1992's Tom and Jerry: The Movie). His only notable vocal sounds outside of this are his various screams whenever he is subjected to panic or, more frequently, pain. He is continuously after Jerry Mouse, for whom he sets traps, many of which backfire and cause damage to him rather than Jerry. His trademark scream (which, ironically, was originally done by Butch in Springtime for Thomas) was provided by creator William Hanna. Hanna's recordings of Tom screaming were later used as a stock sound effect for other MGM cartoon characters, including a majority of Tex Avery's shorts.
Tom has changed over the years, especially after the first episodes. For example, in his debut, he was quadrupedal. However, over the years (since the episode Dog Trouble), he has become almost completely bipedal and has human intelligence. In 1945 shorts he had twisted whiskers and his appearance kept changing. In the 1940s and early 1950s, he had white fur between his eyes. In newer cartoons, the white fur is gone. As a slapstick cartoon character, Tom has a superhuman level of elasticity.
