I was going to say try a grooming glove, they work good at removing dirt dandriff and hair! I dont personally have one Nut I want one lol. My cat alwasy gets matts and he is come and go come and go, *outside cat* my brother never brushes him because he stinks. , so me and My mom have to cut out mats and stuff all the time which is very painful for our kittie, he has very long hair to. My brother is so irresponsible thats why he doesnt have any pets but a cat that hardy is ever home. and when he does come home I end up having to feed him. sorry atarted to vent there.
