Things to note when choosing an original hamster:

1. Observe the appearance first. You should choose a hamster with intact limbs, bright eyes, no eye mucus, no runny nose, and well-shaped ears. A hamster with no bite marks all over its body.

2. Check whether the hamster's teeth are complete, whether they are too long or broken, whether there is hair loss on the body's hair, whether there are obvious tumors, etc.

3. There should be no spots within the hamster’s tail and hamster belly. If there are spots, try not to buy them.

4. When the hamster is moving, the walking and running posture should be normal, with no stiffness, and no redness or acne on the skin.

5. There should be no urine stains on the hamster’s butt and the whole body should be kept dry. It is best to be in a good mental state and respond well to interactions. It is best to observe hamsters in the evening. Hamsters are nocturnal and may not wake up during the day, but it is accurate to observe hamsters in the evening.

6. Try to buy hamsters that have just been weaned and can live independently. Hamsters of this age are very receptive to humans and will become very close to them after a short period of feeding.
