I voted "no way", but my answer really should be "rarely". Every one of my cats got a bath soon after they were trapped. I've bathed them a few other times, but it's not too often. Sundae went through a phase a few years ago, she'd dart out of the door and roll in the sand. I'd run out after her, almost always getting there just a second after she began rolling. (She looked like a chinchilla in a dust bath.) I'd then have to bring her in and bathe her every time.
