Pink Pajamas(1964)

Night has fallen, and the Pink Panther is looking for a place to sleep. A flop house denies him access, but he fortunately finds a key on the ground that gives him entry to a man's home. The man, a drunk, arrives home after one of his binges and, casting eyes on the pink feline in his bed, thinks he's having an alcoholic hallucination so he calls Alcoholics Anonymous to send someone to help him quit drinking.
