Here's why you might be thinking this:
* Mutual grooming: Cats do sometimes groom each other, but this isn't primarily about bathing. It's more about social bonding and strengthening their relationships. It's a way for them to show affection and trust.
* "Bath" might be a misnomer: When cats groom each other, it's usually just a quick lick or two on a specific area. It's not a full-body bath like you might imagine.
