I purchased this for my dad’s car who is older and has started to get matted fur. She is a very mean cat to everyone besides my dad and with the mats she was even angry towards him. We have used this a few times on her and it seems like it doesn’t hurt her as much as the original comb we were using. It’s working good for relieving her mats!
