The reasons why cats become less clingy when they grow up:

1. Their personalities become independent. As cats grow older, they also develop the ability to think independently. Cats are originally solitary animals. When they grow up, they no longer need to rely on their cat.

2. Start to hold grudges. When cats grow up, they are not as easy to fool as they were when they were young. After beating the cat, it may be remembered for a long time.

3. Territorial awareness. When your cat is young, you are its food and clothing parent. But when the cat grows up, you are a "slave" in its eyes. In the cat's world, all areas in the home are their own territory, and you are just a "sojourner".

The reasons why cats are clingy when they are young:

1. The body is too small. In fact, some cats seem to be very clingy when they are young. In fact, it is because their bodies are not fully developed yet and they cannot break free from the "shackles" of their owners.

2. Physiological needs. When a cat is very young, it needs food and warmth to survive. If the mother cat and father are around, they will definitely rely on their parents, and they will definitely stick to their parents.

3. Psychological needs. Kittens are not well developed physically and mentally. When they are very young, they can only rely on their owners. Many kittens crave someone to take care of them.

4. Personality issues. Different cats have different personalities. Some cats don’t like to cling to their owners, whether they are children or when they grow up.
