Who's Kitten Who?

About this title

A baby kangaroo, Hippety Hopper, breaks free from a crate at the Zoo Office and hops into the house of Sylvester Cat and his son, Junior. They mistake Hippety for a giant mouse, and Sylvester is pummelled again and again by the playful kangaroo, causing Junior to put a paper bag over his head in shame for his father.
