I think it is useless as it does not stay up in an erect form as shown on the picture. I am very disappointed, my rabbit is very barely able to get in or out. I will be trying to take a coat wire to weave in and out of the fabric to create the necessary form. However, as important is I tried to cancel one order less than one hour after it was ordered, not realizing initially that I had duplicated the order and was unable to cancel. That was very disappointing and I found it rather suspicious from an ethical business aspect. So all way round it was a very disappointing order and experience with Wayfair.
