My male cat has been on a prescription diet for urinary problems :
How long does he need this special food and also now his fur is clumping in big wads - is this due to his food and what can I do to help him ? It looks like it would be painful but doesn't seem to bother him.
You have to talk to your vet about this. The matting is probably not related to the food. You should let your vet know about this as well. vetcare
