I got my rabbit a new house a few weeks ago. It’s two stories. She has refused to move between the stories. Not for food. Not for toys. Not for her favorite treat (bananas). So she’s been hanging on the bottom shelf till she could figure it out.
Tonight, she was throwing her food bowl around demanding food, and so @dragoness moved her bowl to the upper floor until it was dinner time. And Tater Tot, that little stinker, hopped up to the upper floor for the first time so she could keep throwing it around.
