Its exciting to have a clean dry cage! Although its the same setup every time, they have to explore every nook and cranny, in case anything has changed (sometimes the fleece, sometimes the cozies, and there's always new hay and pellets). Hay needs taste-testing, pellets need eating and one needs to try out the obstacle course.
At some point, Bertie gets goosed by Pinni and that really sets her off. She's a very bouncy Bertie!
Its not the easiest to see with the grids in the way. I'll need to see if I can get the camera a bit higher and pointed down into the cage to try and capture their utter goofiness.
