Is insulinoma inherited?  Our ferrets who were sisters got insulinoma.
The third, unrelated, ferret does not have it so far at age 6.  Food and
living conditions were/are the same for all.  However, the insulinomic
ferrets came from a private breeder and were spayed late at several weeks
while the third ferret was spayed early by Path Valley Farms.
