I am posting this for a new member.This is a friend's cage from when she lived in a smallapartment. I think she also put scrap linoleum under thecage. The cage is made of Nice Idea Cubes fatened together.
That's almost exactly what all my rabbits livein. Their cages are all 3 squares by 2 squares by 2squares. They only have 1 shelf and it's covered withcardboard in case they chew it. They are stacked 2 cageshigh, and have plastic between them, although the linoleum sounds likea great idea.
