1. See if hamster's eyes are big and bright (many girls especially envy hamster's eyes). If the hamster's eyes can't be completely opened, its eyes are dull and there is gum in the corner of its eyes, it means that the hamster is unhealthy and it is not recommended to buy it.
2. See if the coat color of hamster is shiny, smooth and shedding. Hamsters generally prefer cleanliness. If the coat color is dull, not smooth or falling off, it means that the hamster is sick or old.
3. Look for bite marks on hamsters, especially on their ears. If there are bite marks, it means that this hamster is weak or sick and has been bullied and bitten by other hamsters.
4. See if the hamster walks harmoniously and pay attention to whether the limbs are sound. Hamsters, especially when they are young, are often carried around by their mothers because they are naughty. It's easier to hurt their limbs at this time. If hamsters lose their forelimbs, it will be very troublesome to eat, which is not conducive to keeping with other hamsters because they can't grab healthy hamsters; If a male mouse loses its hind legs, it is tantamount to depriving it of the right to be a mouse father.
5. See if the hamster's tail is clean and the poop is dry and hard. If so, hamsters may have diarrhea. If it is serious, you may suffer from wet tail disease, and time is running out.
Finally, I personally suggest that beginners should buy Gakaria hamster (third-line hamster), which is softer and easier to get close to people. And it is better to buy a newly weaned mouse, which is more conducive to cultivating feelings with you in the future.
