I bought one of these, but my mini-rex bunny won't touch it. He tried to use it a few times, but didn't like it. I tried packing it full and packing it lightly with hay. He prefers his hay in boxes, in a hanger on his cage, and on the floor in his cage and run-around. I hear some bunnies do like it, though. It spins fine, but load it carefully or the plastic sides will pop off the center wire part - it'll snap back together, but the hay will pour everywhere on the floor or where ever you are when you're loading it.
