Under XXL really one imagines something else than a rodent home, which not nearly equal to the minimum dimensions. Mandatory for hamsters are at least 100x50 cm floor space, is on one level. This fills the cage not unfortunately. Even mice need more space! Anyone who has seen these animals only in a too small enclosure and then in a species-appropriate, large enclosure, will never set a little thing again! They bloom on and correct their behavior is completely different! Please let the fingers of something, out of love for your pet!
