to: Pat Ball <> Subject: Research Unprofessional studies done by ferret groups have turned up no rhyme or reason for insulinoma or lymphos - i.e. - we don't know what causes them to grow in the first place or why some ferrets get them and others don't. Now, as for adrenals, I have it on good authority that they are regarded as a genetic disorder, magnified by close family line backgrounds - NOT due to early spay/neuter as was once reported in the medical journals. Adrenals can be avoided by researching your ferret's background if you are buying from a private breeder. As to convience ferrets, which are in most pet shops, you can not know what background you will be receiving, but keep it in mind that this problem exists with most "farm" ferrets and backyard breeders. shelter ferrets which are of the pet shop origins pose the same risk. BUT NOT ALL FERRETS FROM PET SHOPS WILL GET ADRENALS, so don't worry for naught! Adrenals are controllable if caught at the right time and by a good vet.
