Tom An ordinary gray-and-white house cat of no great intelligence, Tom is driven by three goals: to eat, to sleep and to catch the mouse, Jerry, and eat him. Unfortunately, his plans are constantly thwarted by the quick-witted little rodent. Jerry A quick-witted, audacious little mouse who lives in the house with Tom, Jerry can never seem to stop himself from teasing his feline nemesis. His greatest pleasure comes from thwarting Tom's every attempt to catch him.
