I was wondering what book would be best to get (beyond the Ferrets for
Dummies) for medical care information for ferrets.  The main three I've
heard of are:
 
Essentials of Ferrets by Dr Karen Purcell
Ferrets, Rabbits, and Rodents by Hillyer and Quesenberry
Biology and Diseases of the Ferret by JG Fox
 
Any comments or recommendations?
