On the subject of which ferrets are more likely to get adrenal tumors, one of our vets who sees a LOT of ferrets has told us that, given the relative population sizes, he sees proportionately the same numbers of Marshall Farms (early neuter) ferrets and private breeder ferrets that weren't neutered until later in life. Given how much larger the population of MF ferrets in this country is, it's easy to say that they get more adrenal tumors, but his experience (and ours!) doesn't seem to bear that out.
