Cartman lives with his mother. He previously had a pet pig and cat, but they both stopped appearing in episodes. In the original pilot episode, Cartman and his mother are seen eating dinner with a man and little girl, presumably his father and younger sister. Whilst episodes have been dedicated about the identity of Eric's father, nothing has ever been said of the mysterious sister. It is eventually revealed that his father is that of Mr. Tenorman, father of Scott Tenorman, Eric's one-time rival. What makes this worse is that, in one episode, he grinds Scotts' parents into chilli after they stole a pony and feeds it to Scott. With this information, that means that in reality, Eric grinded up his own Father.
