I mean, simply FANTASTIC!! I tried everything: brushes, toothbrushes, gloves, either too hard or with stiff bristles, and scratched the cat, nothing... it's true that the bristles are more sparse than they appear in the photo, but trust me, I have over 10 cats in the house and I'm still ordering more for my mother, who also has 7 or 8 cats... massage the cat, it likes it, it purrs, and then all the hair comes off easily!! And the hair stays nice and clean and shiny... to say they're fantastic is an understatement!!!
