I love these there's three brands listed in this thread...I use the medium best pet from Amazon it was the cheapest and they're great for portability and storage.

My mini schnauzie figured out she can escape if the floor isn't anchored down though...but she's quite rough...a slatted wooden children's play yard also works great for escape artists if the slats aren't too wide.
