I have tryed several other items to keep my pet in oneplace......nothing worked until I found the white plastic play pen. I use it in doors mostly. I LOVE IT !! He now, cannot jump over the top to get in the living room. I found it to be built very strong and durable,the price was also in my range.Received it within the time posted.I'm sure I will be ordering something else soon. I plan on ordering the cat post for christmas for my daughter's cats.Maybe a few other things.[...].Isabel moore = Idaho
