Cats are in the moulting period 4-6 months after birth. In the fifth month, breeders can feed cats hair removal cream. Hair removal cream can help cats vomit or expel hair balls in their bodies. Eat about 1 cm each time and feed it 1-2 times a week. Cats like to lick their own fur and eat the hair into their bodies. Breeders can use hair removal cream or cat grass to help cats reduce body hair.
