If the cat's hair is knotted into a hard lump, it is recommended to spray it with knotting water, and then use a comb to comb it through little by little. Knotting water can be purchased in general pet stores or online. If the owner doesn't want to go to such trouble, he can directly push off the knotted hair with a clipper, or cut it off with scissors. You can also send your cat to a pet store for cleaning and care.

After the owner combs the cat, he gives the cat a bath. The owner should prepare warm water and then use pet shampoo to bathe the cat. When the owner bathes the cat, it is best to scrub it repeatedly. Some hair knots may be easier to open after being lubricated by shampoo. After scrubbing, the owner should dry the cat, and then comb the cat while blowing it.
