I have 2 petmate animal pens, the smaller one is 3ft by 2.5ft by 2ft 2 in. And include a plastic bottom. This one folds in on itself for easy storage.
Asking 50$ for it. Obo

The second one is a little larger. It is roughly 3ft wide by 3ft 7in tall, and 4ft 5 in long. It doesn't have a plastic bottom and is in peices, meaning you would have to hold it together with zip ties or bindertwine. It does have a door on the front and a door.
Asking 100$ for it. Obo

Both are in fine working order just aren't used anymore.
