All 6 of my ferrets (ranging from 8 months to 3 years) have yellow fur. Especially my black eyed white and my albino. When they were younger they were white as snow. My sables undercoats are also yellow. My friend brought over her 5 month old male. He had a pure white undercoat and deep black guard hairs, no mask-just black circles-like eyeliner around his eyes on a pure white face. Why was her ferret so white? Is it something I feed my babies, or some type of vitamin deficiancy? Can I wash them with something to make their coats not as yellow? I feed them Iams kitten food and wash them once every 2 weeks with Ferret Glow. Are my ferrets just different types of ferrets then hers? Vanessa [log in to unmask] [Posted in FML issue 1556]
