Query: Miracle worker? No. Great Cat brush? Yes.

The furminator is without a doubt the best cat brush I have ever used. It works very well, much better than standard cat brushes or static mittens or any of that stuff. However, please don't buy this thing expecting that your cat will miraculously stop shedding. It just doesn't happen. It took me about 10 days of daily brushing (multiple times when possible) to get my cats to the point where they were "clean". The first few days get them used to the feeling and give you time to find the right angle and stroke so your cat doesn't yowl and turn and bite you, or run away from home because it thinks you are given to torture. Not that this happened with my cats, but you never know... Anyway, after the trial period, it is much easier to get at them because they are used to the metal and in some cases they even learn to love it. Once you have thoroughly "de-shedded?" your cat, once or twice a week maintenance is all that's required. Great product!
