1. First of all, you need to give Xu a comprehensive physical examination to ensure that he has no other physical diseases.
2. Give enough food and water to keep its nutrition and water intake adequate.
Provide Xu with a suitable living environment, including a cool place and a comfortable bed, so that he can rest comfortably.
4. Give Xu proper hygiene management, keep his hair clean and tidy, and regularly carry out pest control and insect repellent.
If many kittens have other health problems, they should seek medical advice and receive professional treatment in time.
After completing the above steps, you can try to have a conversation with Xu and select the "Dialogue" option. If Xu has a crush on you, she will talk to you and maybe join your team. If Xu kitten doesn't like you, then you need to continue to improve your sensitivity in order to establish a better relationship with her.
