I have tried just about everything to cut the mats off of my uncooperative Maine Coon cat. She won't let me brush her and hates it when I try to remove the mats, but I can't imagine it's comfortable to have knots in her fur, so I purchased this comb with a built in blade. It works great because I can comb under the knot and saw it loose (very carefully). I can usually get a knot or two off before she gets aggitated. I was previously using a smaller version of this product marketed as an eyebrow shaper. I'm sure it works great for its intended purpose, but I have no tried cutting my own hair with it. #RankBoosterReviews #Sponsored #Carejoy
