Cheese It, the Cat! (1957)

Continuity mistake: When Ralph is walking up the steps to his apartment, he has a present in his right hand. The present disappears when he goes through the doors, but re-appears when he enters the kitchen.

Trivia: When Ned is launching Ralph on the bottle of champagne, the label on the bottle says "Selzer's Champagne Extra Dry" - a reference to the Warner Brothers producer Eddie Selzer.
