Pros: Like a kitty massage. Gets some loose fur off of a short hair cat. Good for kitty bellies.
Cons: would not work on a long-haired cat.
I purchased this brush specifically for the short-haired cats in the family and they really love it. One cat nearly falls asleep while I brush him. He even lets me brush his belly with it. The nubs are large and flexible and really do seem more about feeling good rather than really brushing. When I pick up the brush, the cats try to act casual as they run over for their turn.
