I bought two of these pens to put my cats in them when I'm not home.  My cats are little terrors when I leave getting into blinds and bending or chewing on them.  Well, no more!  This is a great product and sturdy. I am very happy with this puchase and my cats are happy as well.  I hooked toys between the bars for playtime, they have a bed and food & water and a cat box....a kitty hotel!
