Amy Cada wrote about her informal study of early neuters and the incidence of adrenal tumors versus animals neutered at a later age. Amy, I have worked worked in laboratories analysing animal data for 20 years, and *if* the groups were indeed random and from the same source, you have a highly significant correlation between early neutering and the development of adrenal tumors. Lacking an appropriate scientific journal to publish this in, I would say you should tell everyone you know, post it anywhere you can find, and send it to any ferret/pet publications you can think of! This is a *very important* finding, verifying what many veterinarians have felt for some time. Thank so much for this information! Document it and send it out!!
