My husband has a knack for putting things together but we had a heck with this item.  We could barely fit the tent over the posts and zipping the top part to the bottom.  The posts are plastic so if we tried to bend them a little to fit the tent they would've snapped in half.  When we finally got it together I put our classic littermaid in it.  The opening is not very big so the litter box doesn't come in and out of the tent easily when I'm emptying the receptacle.  We have a 2 yr old cat and 2 newly adopted kittens so the littermaid gets a lot of use and so far it's done a decent job keeping litter from going everywhere..
