Get to know Biothane:  It is a very flexible, yet sturdy material that is a great option for active pets!  What makes Biothane so unique is it's ability to be cleaned so easily!  It's known to be waterproof, stink-proof and stain-proof!  Not all Biothane is created equally, we use genuine Biothane made in the USA.
