The Shed Ender works very well. But it doesn't end shedding. I have a short haired cat that sheds much more than my other cats. I would comb her and brush her and it just never seemed to make a difference. She just kept shedding the same amount. So when I saw the Shed Ender I just had to try it. I was immediately shocked by the amount of fur that this comb removed. It looked like the fur from a whole cat. It was unbelievable. was very impressed with it. I am pleased with this product because I honestly wasn't expecting it to end shedding. It has helped as much as I would expect it could help. It has more than cut shedding in half for my cats. So I'm happy with my purchase. I would certainly recommend this product to any pet owner who is battling shedding. It is a huge help. Nothing will ever end shedding. But this makes enough of a difference to be worth purchasing this product. Grooming is a necessary evil so you might as well help control shedding while you're at it.
