Snowball I was the Simpson's first cat. Although her death was never seen, she appeared in many flashbacks. Her real grave has two current locations, but can still be confusing: Springfield Pet Cemetery and the Simpson's backyard. According to Lisa, Snowball I was run over and killed by Mayor Quimby's brother, Clovis, who appearently got drunk and ran her over. If you look in the photo on the right, then you will see that Snowball was white, not black, as her name entitles. Many people got Snowball I's color confused with the color of Snowball II's fur. She was born on April 25, 1987.
