I did get mine today! I got the leopard one 41" in diameter, which still seemed a little small once I got to looking at it.
Leopard Skin Pet Tent Exercise Pen Playpen Dog Crate | eBay I got it for $40 on Make An Offer.
I love it! So handy, folds into an almost flat tote bag with handles. This will be perfect for visiting! Wish I had this when we had the puppies! It would be great for a momma and litter but then as they start to grow they might chew through. Bigger ones like mine are not likely to chew. Mine seem to love it so far. I have the doors open and a big leopard print pillow in there for them. Another place to play, for now.
They need a little variety -- it is sort of like a child getting a play tent.
