machete (2010)

Unknown.
Not in the actual film, but in the deleted scenes on the DVD release. A violent and kinky hitwoman Boots McCoy uses a cat as a silencer to shoot her victim. Obviously it doesn't end well for the cat!

the cat from outer space (1978)

Zunar-J-5/9 Doric-4-7, or Jake.
A spacecraft crashes on earth and its occupant has to find some "Org 12" (known to us as gold) so that his craft may get back to the mother ship. To do so Jake asks Dr. Frank Wilson (Ken Barry) to help, to comic effect. In the end he decides to stay on earth, in part because of Frank's girlfriend Liz (Sandy Duncan), and her cat Lucy.
