Cats have plenty of connections to Halloween, so it’s fine for them to celebrate October 31st. But there’s no need for them to wear a costume.
Note that Chumley, bless his gentle hearted soul, doesn’t quote get the idea of Halloween and is wearing a pair of Mickey ears, mainly because Alison Ward is wearing them at the Halloween party in her strip.
