You can tell whether a kitten has long or short fur when it's around 3 months old. The length of a kitten's fur is related to its genes. If more parents have long fur, the chances of having a long-haired kitten are higher. If more parents have short fur, the chances of having a short-haired kitten are higher.
You can tell the length of a kitten's fur when it's about a month old. If its fur is generally long, it's long-haired; if its fur has layers of different lengths, it's short-haired. Long-haired kittens tend to have larger frames than short-haired kittens and look rounder from a young age. Even the fur on their necks, faces, tails, and toes is longer and feels softer to the touch than on short-haired kittens.
