kooa Bamboo Comb with Rotating Pins

Here's my experience: I bought the comb thinking it would improve brushing for my two long-haired cats. At first, I didn't notice anything. But gradually, my cats' behaviour changed so much it was obvious: one started growling when I began brushing (never happened before!), and the other would run away from brushing and I had to be clever to catch her. Eventually, I figured it out and went back to my old comb. My cats' behaviour changed IMMEDIATELY! Back to normal.
