Hello. It's a bunny business pen which I got from amazon. I got the 45" one as it fits in my living room but I would have loved to get the larger 55" one. The floor is nice and waterproof which is good because I have it on carpet (!). The only downside is that I had hoped it would just fold away with a concertina effect but because the base has to be attached after it isn't quite as easy as this. It will also be great on my lawn in the summer and comes with a net for the top to stop predators getting in. Looking forward to filling it with toys and treats!
