Our bunnies LOVE this house. We do use this with an extension of 12’ to play as we don’t believe in confining our babies to a small space. The upper level is their favorite part!  They enjoy laying up on top during the day. The hideout on the right is mostly used as a bathroom. Haha! The house was easy to put together and does take about 1-2 hours. We have tarted the top to help with weather as well. Bunnies do chew on the wood inside as well. The pullout tray makes it easy to clean if needed. I loved this house so much I bought two and then bought another to donate to our local shelter for bunnies. I would buy again!!
