Last year we successfully used the blue plastic surround to house our baby ducks and geese in outside - it's both weather proof and draft free! - and this year it's the sunroom playpen for our baby goat.
We have a dog crate in the pen, with a heat lamp on top and a heated cat bed inside to keep the little guy warm at night when he's all alone. It works real well and both the blue plastic surround and the towel around the dog crate keep the little guy out of drafts (the sunroom windows do not completely close).
Oh, the ladder is so my 32+ lbs toddler can go in and out by himself!
