How to distinguish long-haired and short-haired kittens at 40 days old:

1. If it is a long-haired cat, its overall hair will be very thin even when it is about 40 days old. Flat and long, while short-haired cats are different. Short-haired cats are layered.

2. The hair of long-haired cats feels softer, while the hair of short-haired cats feels smooth.

3. If one cat parent has long hair and the other has short hair, unless the short haired parent has a recessive long hair gene, basically only short or medium-short hair will be produced.

4. The skeletons of long-haired kittens are larger than those of short-haired kittens. They have been very round since childhood. Even the hair on their necks, faces, tails and toes are very long, and they feel shorter than those of short-haired kittens. The hair is softer.

5. Two-month-old kittens can tell whether they have long hair or short hair through the difference in body hair. Long hair feels softer, while short hair has a more pinprick feel.

6. When short-haired cats are young, they only have a layer of lanugo hair. Although some of the protruding guard hairs are relatively long, at first glance they appear to be unevenly long and short. After the short-haired cat moults, Only then will all become smooth and close-fitting short hair.
