Now in the cold winter, every household has turned on the air conditioner to keep warm. Many friends who raise hamsters at home also turn on the air conditioner to keep hamsters warm. In fact, hamsters can blow the air conditioner, but they can’t blow it for too long, because blowing the air conditioner will make the indoor air relatively dry, and if they don’t open the window for a long time, the air will not circulate, which is easy to lead to the spread of bacteria, It is harmful to pets and even human health. Although hamsters have fur, they are also afraid of the cold. In winter, the owner must keep them warm, otherwise it will lead to the decline of their physical function. Therefore, it’s not just to turn on the air conditioner. To improve its living environment, if the temperature is lower than 15 degrees, the owner must put a thick layer of cotton in its hamster nest to keep it warm. It’s best to put some rags in it to give the hamster enough entertainment activities. Some people will stuff absorbent cotton into the nest. Then someone will ask, when should these cotton be changed? Generally, change it every half a week, but don’t change it every day. Hamsters like to stay in places with their own smell. If they change it too often, hamsters will not adapt. The owner should often observe whether the cotton is wet. If it is found wet, it must be replaced in time. In winter, many friends will choose to use the outer layer of hamster’s nest with materials with strong thermal conductivity. Using them to build a nest for hamsters is very warm. Some owners like to give hamsters DIY to their nests, use some woolen clothes they don’t wear, some warm cotton, etc. The nest made by the owner himself will make the hamster feel very warm. You don’t have to worry about making it well. As long as it is suitable for it, it is the best. Many owners give hamsters cages, which are usually iron. In winter, if you want to keep warm, you should choose a plastic cage, because plastic cages are generally airtight. If the weather is too cold, the hamster’s home should not be placed in a ventilated place, or the temperature is too low. You can turn on the air conditioner or heating appropriately to keep warm, but the premise is not to let the hamster get too close or blow directly against it, which is very unfavorable to the hamster, especially the temperature difference in different places is large, so the owner should pay more attention.
