A Mouse Divided (1953)

A very drunk stork mistakenly drops off a baby mouse at the home of Mr. and Mrs. Sylvester Cat. Just as Sylvester is about to make a meal of the tiny creature, it looks up and calls him "Daddy." Moved by this, Sylvester decides to raise the mouse as his own son—but this decision backfires hilariously, as every famished cat in the neighborhood soon comes prowling around his house!
