Snowball V

Snowball V, commonly referred to as Snowball II, is the Simpsons' fifth cat and looks exactly like Snowball II. The Crazy Cat Lady throws the cat at Lisa while she is mourning the deaths of the other cats that she kept Snowball III] and Coltrane).

Biography
After the Crazy Cat Lady drops the cat at her feet, Lisa tells it to leave, because any cat that she owns is unlucky and is certain to be killed. As the cat starts to cross Evergreen Terrace, Gil drives by in his car. Gil swerves to miss the cat, hits a tree, and his car bursts into flames, which means that Gil will be able to use the insurance money to buy food. Since the cat is unhurt, Lisa takes it as a sign of good luck and adopts her.

The cat later becomes overweight after abandoning the Simpsons for brief periods to visit a different family. At the other family's house, she is fed, taught tricks and given the name "Smokey".

Name
Lisa renames Snowball V "Snowball II," in her words, "to save money on a new dish." She also vows to pretend the whole thing never happened (i.e., two adopted cats dying in quick succession). Principal Skinner, who happens to be walking by and overhears Lisa talking to the cat, asks, "Isn't that a cheat?" to which Lisa replies, "I guess it is, Principal Tamzarian."
