Rufus

Re-Animator
Rufus is the name of a fictional cat featured in the 1985 sci-fi/horror film Re-Animator. Rufus was a black cat owned by Dan Cain and lived at his home at 666 Dark More in Arkham, Essex County, Massachusetts. Allegedly, Rufus died when he got his head caught in a bottle. Dan's roommate, Herbert West placed the cat in the refrigerator, which was discovered later by Megan Halsey. Dan and Megan thought that it was extremely insensitive of West to preserve the cat in such a fashion.

Herbert West used his experimental Re-Agent on Rufus bring him back to life - at least partially. As an undead thing, the cat was little more than a psychotic and groteseque effigy of what it once was. Driven insane by its "birthing pains", the cat attacked Herbert West until it was ultimately put down.
