When a cat's fur is matted and shedding, the pet owner should first use a pet pin brush to comb the cat's fur and remove the dead hair. Otherwise, cat hair may fly everywhere. The owner should also untangle the cat's fur while doing so. 
When you encounter small clumps of fur on your cat, you should gently brush them first. When brushing, you should use a loose comb so that it doesn't hurt. If the cat feels pain, it won't cooperate with you.
When a cat's fur is matted and shedding, pet owners should pay attention to supplementing the cat's nutrition. Some cats have poor fur because of insufficient nutrition, so pet owners should adjust the cat's diet and feed the cat some foods that are good for its fur, such as fresh fruits and vegetables, egg yolks, and salmon scraps.
