Adrenal growths are found in any nation, though there may be more here in the U.S. Heck, one thing that the Netherlands is famous for in ferret circles is having one of the world's premier researchers into adrenal disease, Dr. Nico Schoemaker. So, yes, they certainly have adrenal disease there. Sorry about what your little ones and you are going through; sometimes "Buyer beware" strongly applies. BTW, some states have state "Lemon Laws" which may help you get Carolina Ferrets to pay toward their surgeries and meds.
