Is it appropriate to keep hamsters in fish tanks or tidying boxes? Can you get some air? Will it be sultry in summer?

In summer, mice will stick to the cylinder wall to dissipate heat. But don't keep it in a fish tank in winter. It's very cold. If you use a sorting box, you can have a radiator or a small porcelain nest.

Use a higher fish tank or sorting box, and don't cover it. Ventilation is enough. . . Don't put anything too big in it, lest rats and mice step on it to escape ~
