respectfully-- none of this has been proven to date only summized.
I have fferrets who were altered later in life age 3 years-- who have lived
until the age of 9.5 years without ANY SIGN of adrenal disease.. they
finally died of renal failure-- old age...
I personally do feel that light is NOT the r4eal issue rather that the
absence of hormonal input due to castration and spay which wears on
efficiency of the endocrine system is the ultimate culprit.
I realize am only one small voice with a small sampling of ferrets.... but
future studies , I do believe will back this up.
There is already studies of this sort on other mammals.
