The reasons why kittens tremble:

1. Kittens that have just been brought home will feel nervous and tremble in the face of a strange environment.

2. Kittens may tremble because of fear when encountering danger or powerful enemies.

3. When the temperature is low, cats will shiver because of the cold.

4. Cats suffering from neurological diseases will also tremble, and may also experience symptoms such as epilepsy, cramps, unsteady walking, and opisthotonus.

Solutions for kittens shivering:

1. If it is caused by cold, you need to take corresponding measures to keep the cat warm and try to create a comfortable life for the cat. The environment and temperature should also be suitable to prevent cats from catching colds.

2. If it is caused by stress, you need to gently stroke the cat to soothe the cat's mood and provide a quiet environment to avoid causing a stress reaction.

3. If it is caused by neurological disease, it is best to take the cat to the pet hospital for an MRI examination.
