Debi, I have no scientific evidence on this question, but I have had more than a few ferrets with definite color preferences. I have one at the moment -- and he's not the first to exhibit this behavior -- who preferentially sleeps on or in things at the red end of the color spectrum; he will choose red, organge, or pink bedding over an identical item of another color every time. In the past I've had a few who showed a similar preference for blue or green bedding, and my first ferret flatly refused to sleep on anything that wasn't blue. So I think it's safe to assume that ferrets can distinguish at least some colors, but (like the rest of us) they may have different favorite colors. Before you select a color scheme for your ferrets' room, you might want to ask them what they prefer. ellen & the fuzzballs -- mailto:[log in to unmask] [Posted in FML issue 3201]
