For example: 1. Choose a hamster with eyes but no shit.
2. See if the hamster has a runny nose. If there is, don't choose.
3. Whether the shape of the ear is intact and whether there are traces of being bitten. This hamster is too weak or sick to be bullied and bitten by other hamsters.
4. The teeth don't extend outward, and the hair color is bright. Check for hair loss or tumors.
5. There should be no spots on the tail, and it is not good near the stomach, indicating that this hamster may have diarrhea.
6. When walking is abnormal, there is no feeling of stiffness, and the health of limbs is also the focus. If everything looks good, there should be no problem.
7. There should be no urine stains on the buttocks. If there are, don't pick them. Because it's probably sick.
Finally, choose a hamster you like. Besides its coat color, you should also consider whether it will be close to the people.
Generally speaking, Syrian hamsters and Gakaria hamsters are easy to get close to each other for a period of time, while Campbell hamsters and Roborovski hamsters are more difficult, especially Roborovski hamsters are timid and sensitive animals, so it may take some time to gain their trust in you.
As for whether to raise a good one or a pair, basically, if it is a Dover hamster, it is better to have more than two. If it is a golden mouse, it is possible to keep one. If you want to keep a pair, it's better to keep them separately. When you want to mate and reproduce, put the female mouse in the cage of the male mouse, and then separate after mating.
After successful mating, the mother mouse will be grumpy because of pregnancy. At this time, it is best not to touch it to avoid being bitten by it. Unless, of course, it's docile enough to listen to you. Don't put male rats and female rats together during childbirth.
Finally, in fact, hamsters in the flower and bird market are not easy to raise and are easy to get sick and die. It's best to buy it online, and it's also cheap. Online shopping is generally domestic and very healthy.
