I have recently purchased a larger cage for my four babies and the size has necessitated it being moved from a very lighted (windows) kichen to a very dark (interior room) family room. I'm now afraid that they will become vitamin D deficient due to a lack of natural lighting. There has recently been some discussion on natural lighting for ferrets when they're not getting enough. Can someone email me with the information I need to purchase lights for the ferrets' cage. I would like something that could be clipped to the top (outside) of the cage to leave on during the day. Thanks for your help. I don't even know where to begin. Katharine Lily, Lany, Blaze, and Champ [Posted in FML issue 2053]
