I have been using the furminator about a month and I noticed it removes the most fur when I comb over the lower back region of my cats, especially just in front of the tail. I can comb lots through the rest of their bodies with little hair being removed, but it removes a sizeable tuft of hair with every stroke when it is near their lower backs. My cats shed quite a bit for being shorthairs (I'm always picking up tumbleweeds from the corners of rooms), so is this just fur that they can't reach with their tongues which never gets dislodged, or do cats have a lot more hair there than other parts of their bodies?
