Rats learn to recognize their owners from an early age. Rats have very high IQs. They will recognize their owners after being kept for a long time, and they can also cooperate with their owners to complete various trainings. However, rats carry many bacteria, which may cause certain harm to human health. It is not recommended to raise wild rats. Try to choose pet rats, such as hamsters, mice, etc., which are safer and harmless.

2. When seeing the owner holding food in his hand, he will crawl to the owner and ask for food.
3. Will tidy up his fur in front of his owner, put his ears down, and no longer be vigilant at all times.
