My golden bear doesn't eat much. He doesn't like playing anymore. Is he sick? Online waiting.

Now in summer, it will be very hot, and the hamster is still wearing its thick fur coat, which is even hotter.

So, it's probably caused by the weather. You can put a cool towel on its cage to cool down.

Moreover, our mice are a little listless at this time of year, but they will be fine after 8 pm, and it may still be hot.
