It is very common and normal for a cat to purr whenever it comes near me.

1. The purring sound of a cat shows that it trusts the people and things around it. This is a sign that the cat likes you. So in most cases, if a cat purrs, it means the cat feels very comfortable and relaxed.

2. If the cat keeps purring, it may be a respiratory infection. The owner should pay attention to the cat's physical condition. If any abnormality occurs, he should be sent to the pet hospital for examination and treatment immediately to avoid aggravation of the condition. You should spend more time with and care for your cat.
