It is generally normal for a kitten to purr while sleeping. This is a sign that the kitten is sleeping comfortably. Parents do not need to worry. Some kittens may purr due to physical discomfort. Parents can observe the cat. You can judge whether the kitten is sick by whether there are other symptoms. If you find that the kitten is sick, you should take it to the hospital for treatment in time. Do not use medicine randomly at home.

Tip:

Cats usually make low sounds such as purring when they are comfortable, and they usually make sharp sounds when they are in danger and uneasy. When you are sick, you usually make no sound or make a small sound.
