Although my cats have backyard access with cat fencing, I needed to keep them safely contained while my house was being sold (so during open houses and viewings). This went together well (easier with 2 people, but doable by 1) and is quite sturdy. I added extra shade/rain cover over the top. There are several doors included. My cats enjoyed it so much, they'd go and put themselves in it even when they had free access in and out!! Can definitely recommend the product.
