I read this book at least 10 years ago. There is a woman who meets a man while traveling through a massive warehouse. (The setting is sometime in the future after everything has collapsed) The warehouse is so large they are in it for days. He has a companion, something that looks like of like a grateful dead bear. It has to drink his blood for sustenance. At some point, once they exit the warehouse, the girl ends up bonding with one too, but it doesn't drink her blood. When females try to bond with one in the blood drinking sense, it either kills them or drives them mad.
