Solutions for a timid kitten:
1. Pet and hug your cat often to make it feel safe and relaxed. It will gradually become bolder.
2. You can also invite friends over to play more often. When the cat has seen more people, it will be less timid. 
3. Play with your cat more often using a cat toy, and let it touch the toy a few times occasionally. This will make it more confident and can improve its timidity and fear of people.
4. Owners should talk to their cats more often to let them become familiar with their voices, get used to their company, and increase their sense of trust.
5. Take your cat out for walks more often so it can interact with the outside world. After a few walks, it will no longer be afraid of people.
