My cat is getting hard lumps of matted fur and I don’t know how to deal with it. I thought we were doing well with brushing him regularly but recently he’s been getting these stubborn knots. I’ve tried a special de matting comb and it cleared one side quite well but the other side the knots are just too tight and it’s pulling. I’ve been as gentle as possible but now he’s hating being combed at all as it must be sore. I’m so worried about it as I’ve read that if not removed it will only get worse and become a big problem for him.
