Query: The Miracle Brush

WOW! I thought I had good brushes for my lab and two shorthaired cats, but The Furminator is amazing. I just wish I had discovered it sooner. I bought it for $9 more than Amazon is selling it for at a pet store. Now I'm buying several more as gifts from Amazon. Although it's still expensive, it is worth every penny. The amount of fur this brush removes is incredible.
