The cage I ordered from quality cages came today, the baby safe version of the chinchilla Townhome. Everyone seemed to love having more than double the room than their old cage. Then they started climbing. The babies were climbing up to eight inches up the walls and jumping down. Mira was climbing to the very top and jumping down. Is this safe? I didn't add any shelves, and didn't think Chinchillas could climb that high! I don't want anyone getting hurt, but the old cage was way to small for Mira and two week old kits. Nothing is on top of the cage right now, it was only there when setting up the cage.
