I have four ferrets, two MF and two non-MF. My two non-MF guys, Martin and Sybil (a Canadian and Washingtonian, respectively). Martin has gained WEIGHT for winter (he did last year as well) and has a nice thick winter coat. Sybil has a nice thick winter coat too. My two MF guys do not. At all. Linus and Zooey are 3 1/2 and 5, respectively. They have always been skinny, never done the seasonal weight thing, and have never done the winter coat either (not really, not as dramatically as Martin does). Is there a connection here, or is it just my MF guys? Minta [Posted in FML issue 2512]
