It's amazing how well this "deshedding" tool works. If you have a long haired cat or dog or your animal companion has a thick undercoat, this tool is far superior to any of the conventional combs and brushes on the market. The teeth on the metal comb pull out the dead undercoat. By the end of the first week of using this, Porter, my chubby Main Coon kitty, appeared almost svelte because so much fur had been taken from his undercoat.
What it can't do is to eliminate those nasty knots; they still need to be cut out with scissors. Yep, The Furminator is pricey, but well made and effective. You can find it in Portland at Freddie's and most pet supply stores.
