LOL. well other than teh revelation of "oh i was your ex boss, please don't hate me" and doubling down on the 'pampering', i don't think they'd really do a plot point of him being 'exposed' lol
That said, considering 'working dogs' are a thing and border collies and poodles being known as 'smart breeds' i wouldn't be surprised if there really were cats that enjoyed dressing up/could dress up and change on their own
Or the cliche "Cats understand you/are able to do X thing, they just choose not to"
