Does this thing work? Does the cat actually use it?
I screwed a natural bristle scrub brush onto the vertical low side of my desk
and my cat likes to brush on that, but not enough to be called good grooming.He
used to rub on my desk anyway so I thought I'd put that there for him. He likes
to rub his face on it.
