That Darn Cat (1965)

Hayley Mills stars as a young woman with an active imagination who contacts the F.B.I. when her cat suddenly sports a wristwatch around his neck. She’s convinced it’s the tip-off to crack a baffling bank robbery and kidnapping case. Dean Jones is the allergic federal agent who sniffs around for clues only to find love in the air. An impressive supporting cast – Frank Gorshin, Elsa Lanchester, Roddy McDowall and Ed Wynn – add to the nonstop zaniness.
