Deducted a star because it is a pain to build, and it is very flimsy without a hefty amount of zip ties. Just took the top floor collapsing for me to realize that lol. The pigs also love to fling poop, hay, and food out of the cage. Not my favorite thing to step on in the morning. Other than that it does its job well. Much easier to clean than a regular wire cage due to the coroplast. My piggies love it though!
