Daphne's Aunt Olivia lives in York Towers, which is an actual apartment building in Manhattan built in 1960.
The second consecutive episode to feature a feline-themed monster.
Some video releases used an alternate title for this episode: "Who Was That Cat Creature I Saw You With Last Night?"
The show switches to a more rubbery animation style when Scooby gets stuck in an elevator with the Cat Creature.
