Willard (1971)

Chloe

When Joan (Sondra Locke) gives Willard Stiles (Bruce Davison) this cat to be his companion, you can tell that he is less than pleased. The rat-obsessed Willard soon disposes of Chloe by giving her away.

At least it's better than the more tragic alternative which happens in the remake.

Willard (2003)

Sculley

Cathryn (Laura Harring) should never have given a cat to the crazy, rat-loving Willard (Crispin Glover).

His army of rats attack and kill Sculley as soon as Willard places the unfortunate feline inside the house.
