It is the difference between hair length and density. Ragdolls will undergo hair changes when they are one and a half to two years old. Ragdoll cats with explosive hair will be more fluffy, dense and slender than before, making the Ragdoll cat more beautiful. ; The hair of a Ragdoll cat that does not have explosive hair will stick to the skin, and the hair will be short and sparse. Breeders should feed more foods containing protein, vitamins and other nutrients, and comb cats more often to speed up hair growth.
