Hamsters can use the air conditioner all night. In the hot summer, air conditioning is the simplest, most convenient and most effective way for hamsters to cool down. But be aware that hamsters are very sensitive to changes in ambient temperature, so they must be cooled down slowly. To recover the temperature after turning off the air conditioner, it is best to wait until the indoor temperature is not much different from the outside temperature before opening the door. Also be careful not to blow the air conditioner directly on the hamster, avoid the downdraft, and choose a location that is sheltered from the wind.

In addition to blowing the air conditioner to avoid the heat, hamsters can also cool down in the following ways:

1. Purchase a simple igloo made of ceramics or an igloo that can hold ice packs. Both types of igloos have a cooling effect.

2. Due to temperature reasons, hamsters may experience a seasonal decrease in appetite, so they can be fed grains and pet snacks.

3. Hamsters must provide enough drinking water to spend the summer and ensure a source of fresh and clean water.
