Cat (sometimes The Cat) is a fictional character in the British science fiction sitcom Red Dwarf. He is played by Danny John-Jules. He is a descendant of Dave Lister's pregnant pet house cat Frankenstein, whose descendants evolved into a humanoid form over three million years while Lister was in stasis (suspended animation). As a character he is vain and aloof, and loves to dress in extravagant clothing. He is simply referred to as "Cat" in lieu of a real name.
