Kittens have a high need for humans during their growth period. They regard their owners as their mothers, so they will crawl along their owners' bodies and up their necks to get closer to their owners. This is what happens to most kittens. This kind of behavior will gradually decrease when the kitten grows older. If the owner does not want the kitten to climb up the neck, he can stop the kitten when it climbs up and regulate the kitten's behavior.
