Drinks on the Mouse (1953)

In the deserted ice-cream parlor, the thirsty mice are never able to drink their concoctions because Katnip the Kat keeps them running for their little mice-lives. But Herman, the brother mouse, arrives with his bag of tricks. Herman tricks Katnip into swallowing a bottle of sleeping pills and, while Katnip snores, the mice enjoy their sodas.
