Snowball was the Simpsons' pet cat, replaced by Snowball II after its death. Snowball was, according to Lisa in a poem, run over by a Chrysler. At a later point it was elaborated Snowball was run over by Clovis Quimby, drunkard brother of mayor Quimby (in a parody of what could be any of the Kennedy brothers or even Billy Carter). Snowball was so-named due to her white color. However, she has been drawn black. Snowball has been spotted in heaven by characters who have undergone near-death experiences.
