My roomate has mild cat allergies. She's not so severe that she can't be around them, but if I don't give them a bath about once a month she starts getting really conjested. The longer they go without a bath the worse she gets. Since their indoor only my options are either bath them, get rid of them, or keep them locked in a room. Since the last 2 aren't an option the compromise is they get a bath. Although I'm not sure which they'd choose sometimes, since that's usually when I trim their claws as well!
