And I had the bestest time with them tonight - I removed the platform in their cage and put in a new stick bridge to hide under, so they now have one each. They loved the new space, so much so that when they thought I wasn't in the room they ran around popcorning like nutters! Running in and out of the bridges, through the hay and then little jumps in the open spaces. Feel like such a proud parent that they have reached this milestone so early - only their forth night home with us !
