I want to mock anything called the "Cat Spa," but looking at this unit, which includes all sorts of little nubs for rubbing and a tooth-cleaning rubber chew with can be filled with catnip, it's hard not to think that cats would totally love this thing. Or they'd be absolutely terrified by it, giving it baleful looks from across the room. Or the latter for a few weeks, then the former.
This is why I never buy cats gifts, but gift certificates.
The Cat Spa is $25.
