How big does a hamster enclosure need to be?

We recommend at least a 100 cm long rodent glass for dwarf hamsters and 120 cm for golden and teddy hamsters.
The legal size is far below this size, but a size of 60 × 30 cm cannot be considered animal-friendly.

In addition, the law stipulates the following for the enclosure: Hiding places, a burrow layer of at least 15 cm, climbing facilities (hamsters do not know height, so do not build over 10 cm high), nesting material and natural wood or softwood for tooth abrasion.
