I am using this enclosure for my cats to go in while I am away from the house or when I have company in, so they do not get outside and get lost.  I use mine inside the house in a large room.  It is a nice size enclosure and it works well enough for what I am using it for, but the doors on it should be a bit higher and wider... it also is a bit flimsy in construction.  For the price I think it could have been a little better quality, but it is working for us for what we are using it for.  It is quite roomy and my cats do like the space to play and move around in it freely.
