i have 3 ferrets. my girl doesnt turn 2 until october and im already scared that she might have adrenal disease. shes geting really skinny and her hair is geting very thin. she looks like shes losing hair on her tail as well. i got notes from the vet that her and her brother are due for more distemper shots. is there a test the vets do to test for adrenal disease? im definetly more scared of losing my ferret but i dont have a whole lot of money right now so does any one know is this may be super expensive to test for and fix/if she even has it? thanks for your help
