Love it . It didn't take long to install, probably 2 hours and just because how big it is . It has a ton of space and I followed every single direction . Very easy to put up as long as you follow the directions and our new kitten loves it.  She actually never wants to come out.  It's great when trying to introduce dogs with a cat because they can still see eachother . And whenever they get introduced I will use it for our bunny . It's great and you can make shift it to anything you want . It was very spacious to fit a cat tower in it and I can still walk around . I'm about 5'1 so I have to duck while walking around my husband is about 6'1 ! He has some trouble but he can surely still fit. My cat is will a little fearful when trying out the hammock that came with it because it isn't that sturdy. Be sure to truly use to zip ties. Don't go around that step . It just holds everything together
