What would be making my cats fur geting in tight knots by his skin?
Brushing will get the top coat taken care of.





To get down to the skin and prevent matting, you need to use a comb.
Reply:He may be unable to brush himself with his tounge. Perhaps he has too much hair, or a damaged tounge.
Reply:i have the same problem. Some male cats do not take such catlike pride in there appearance so they crawl through strange tight spaces and roll in the dirt but hardly clean themselves. Also if he is a long haired cat and you live in a cold area he may be developing a base coat for the winter which is a firm tight mat of hair next to the skin which keeps them very warm and dry in the winter.
Reply:My old ragdoll has gotten to not grooming himself as well as he used to, so he gets mats or knots. I have to cut them out but he is not cooperative.
Reply:He could also have worms.
Reply:Brushes are useless. Use a steel-toothed comb to remove the dead undercoat - that's what causes mats. And what is "often"? Longhaired cats need to be combed at least every other day and daily during shedding season. Shorthaired cats every few days or once a week if very short hair.
