There are some clues to personality in the appearance of any kitten. Please understand each cat has its own distinct personality, and these are generalizations, but they could help you to identify the most likely pet for you. This has left many people assuming that long-haired cats are more likely to be lap cats. That isn't necessarily the case. If the kitten sits quietly in your lap and lets you pet it, that is a better indication of whether or not it will be a lap cat than its hair length.
Body shape is also a clue.
A healthy well-fed, thin, lanky cat with long legs and a long whippy tail will generally be an active cat. It may also be talkative. If it enjoys people, it may demand attention verbally or by doing mischievous things. It may also be able to get into cupboards, open doors-that kind of thing. The stockier-built cat, with shorter legs and a more square body, is generally calmer and quieter, although not necessarily less curious.
