Hoppy-Go-Lucky 1952

Directed by Robert McKimson

Sylvester Cat and his dopey, brawny feline friend, Benny, hunt mice in a warehouse because Benny wants one as a pet. Hippety Hopper, the baby kangaroo, is in the warehouse, and the two cats, of course, think he's a giant mouse. Benny wants him and obliges Sylvester to try and catch the fleet-of-foot Hippety.
