How big should a cage for 3 gerbils be?

For three gerbils, the cage should ideally be at least 24 inches long, 12 inches wide, and 12 inches high. A larger space, such as 30 inches long, 12 inches wide, and 18 inches high, is even better to allow for more enrichment and movement. Ensure the cage has good ventilation, solid floors, and horizontal bars for climbing. Providing ample space helps reduce stress and promotes a healthier environment for your gerbils.
