Construction was easy. Two parts were broken though. One part could not be screwed in because the screws were wider than the wood they were supposed to go into. There is no door to the upstairs, so we had to construct one to look up bunny at night. Only good for one very small animal. My normal sized bunny is squished in this. The pictures with the chicken and bunny make it look much bigger. Kept it due to the immediate need and Covid-19 returns. Would not buy again for the money.
