The reasons why kittens love to lick people:

1. Kittens like each other. Kittens are very cute and simple creatures. When they fall in love with humans, they like to lick each other to express their emotions.

2. Kittens want things from people. Cats do not understand human language. They can only express themselves in their own way through contact with humans, such as being hungry and wanting someone to play with them.

3. The kitten is cleaning. Kittens lick their fur to clean themselves. When a cat licks a human, it may be because it wants to help the human clean its body.

4. The kitten suffers from anxiety. Kittens will lick their fur constantly in order to soothe themselves when they are anxious, and they may also lick people excessively.

5. The kitten wants to declare its sovereignty. After a kitten recognizes its owner, it likes to lick its owner and leave its own unique scent on the owner, proving that the owner belongs to it.
