This brush works just as it says it will. One of my outdoor cats has thick hair that sheds and gets dirty. We used this brush and got so much hair off of him that his coat is a lot lighter and looks and feels healthier. The cat really enjoyed being brushed with it too, and it did not seem like the brush pulled too much or hurt him in any way. The only thing is that I may have bought the bigger one, because this one is a little small for a big cat.
