2, look at the eyes: if the hamster's body is very healthy, then its eyes are also very watery, and its small eyes will also glow. When hamsters' eyes are red, or they often shed tears, or they often have gums, it means that hamsters may have problems inside their bodies.
3, look at the feces: Under normal circumstances, hamster feces have a certain hardness, as big as rice grains, black and tasteless. If hamsters pull out other colors of poop, it may be that the feed contains more pigment, so the owner need not worry too much. But if the hamster's feces are soft or smelly, it means that the hamster may be sick.
4, look at the cheek pouch: food stored in hamster cheek pouch for too long is easy to deteriorate, once the food is moldy, it is easy to cause bacterial infection, then hamster cheek pouch is likely to be inflamed. The owner can check the hamster's cheek pouch irregularly for the smell of food deterioration, or help it clean the food in the cheek pouch regularly. If hamsters suffer from cheek pouch inflammation, they should be treated in time.
5, look at the body temperature: the hamster's body temperature will be a little higher than the normal body temperature of people, but the feeling is not obvious. If you want to measure the temperature of hamsters, you still have to use a thermometer special for bugs. If the hamster's temperature is abnormal, it's because there are some problems in its body.
In addition, the owner can also observe the hamster's teeth. If the hamster's teeth are too long, which affects eating, it is easy to have physical problems, so the owner should prepare molar food for the hamster in time.
