The parts that hamsters like to be petted mainly include the head, back, abdomen, both sides of the neck, ears, and chin.

1. Head
The head of a hamster is a very sensitive area. Gently stroking it will make them feel warm and relaxed. Many hamsters will close their eyes or shake their heads slightly when their heads are gently stroked, showing a pleasant mood.
2. Back
The back of a hamster is not very sensitive, and they can't reach this part by themselves. Therefore, they will feel comfortable and relaxed when being petted. When petting, move along the direction of the hair growth, and the movements should be gentle.
3. Abdomen
Although the abdomen is relatively sensitive and soft, when hamsters trust their owners, they will also be willing to let their owners pet it. Some hamsters will even enjoy this feeling and actively expose their abdomens.
4. Both Sides of the Neck
The skin here is relatively loose and not particularly sensitive. Hamsters usually also like to be touched in this area. But be careful not to touch their heads.
5. Ears
Gently pinch the ears of hamsters with your fingers, and they will feel very comfortable.
6. Chin
This is a sensitive area that hamsters like. Gently stroking it will make them feel delighted.
Precautions
1. Avoid Reaching Out Suddenly
Hamsters are naturally timid. A sudden touch may cause their alertness and defensive reactions.
2. Don't Touch the Head
Most hamsters don't like to have their heads touched and may bite because of this.
3. Avoid Sensitive Areas
Areas such as the mouth, claws, ears, and buttocks are relatively sensitive. Try to avoid touching these areas.
