One problem with reading the Ferret-List submissions is you miss one once in a while. I must have missed the submission regarding ferrets and darkness that seems to have lately precipitated much correspondence. There was much discussion some time ago about ferrets and natural light; the conclusion was that ferrets should receive natural light to minimize adrenal and other problems. So, our two were moved to an area where they can receive it. Now, it seems, there are arguments being presented for keeping ferrets away from natural light and give them total darkness for a major part of the day. This can be confusing. So, what IS the recommended light and duration? Al W. [Posted in FML issue 2511]
