It is a common behavior for kittens to protect their food. They will feel unsafe when eating or be afraid that food will be taken away by other animals, so they will become very alert and sometimes even very aggressive, and will beat other animals back to their original shape.

If your kitten cares about food, you can consider the following ways to help it relax and stop this behavior:

1. Provide a private space for the kitten: let the kitten stay in a quiet place when eating, away from other people or pets, which will help the kitten feel safer and more relaxed.

2. Separate feeding: Give each cat a separate food bowl to ensure that each cat has enough food and water, which will reduce the need for kittens to protect their food.

3. Feeding saturation: provide enough food for the kitten to ensure that it feels satisfied and safe, which will reduce the probability of protecting the kitten from food.

4. Make a music or noise background: Creating a noise background for the kitten will make it feel more relaxed and safe.

5. Stimulate the kitten's desire to play: Before the kitten eats, you can give it some toys to distract the kitten and make it feel happier, so as to reduce its distractions of protecting food.

6. Cat powder: When your kitten eats, put some cat powder, which not only strengthens the cat's nature, but also makes the kitten eat happily.

7. Record the kitten's eating status frequently. When its eating status gradually improves, let the kitten eat meals with other pets gradually.

In short, help your kitten overcome the problem of food protection and take care of it as carefully as possible to make it feel safe and satisfied. If you are in doubt, please consult your pet doctor.
