Siamese cats and Himalayan rabbits have a gene mutation (see Link) which causes a gradual colour shift when subjected to a change of ambient temperature. In a nutshell, they turn darker and fortuitously more heat-absorbing when temperatures drop and turn lighter and more heat-reflecting when temperatures rise. This partially explains why a Siamese's ears, tail and other extremities are darker than the rest of the body.
I propose utilizing this feature in designing a range of fur coats which adapt to keep the wearer at a comfortable temperature over a wider range of the year. To more sensitive readers, I suggest that the manufacturing method should be my Cruelty Free Fur Coat idea (Link) but I will leave it to [8th of 7] to propose more pragmatic alternatives.-- AusCan531, Oct 19 2011 Colour changing cats and rabbits http://www2.gi.alas...Forum/ASF8/836.html [AusCan531, Oct 19 2011] Cruelty Free Fur Coat manufacturing method Cruelty_20free_20Fur_20CoatsBlatant cross-promotion of own ideas.

Hmmm, p'raps that WOULD pose a few difficulties to the seamstress. Either that, or it will necessitate the inclusion of a lot of extra plumbing for nutrient supplies to the inner lining of the garment. In any case, all manufacturing processes can expect to face some sort of technical challenges.-- AusCan531, Oct 19 2011 In that case, shedding may be a problem, but at least stains would dissapear after a while.-- scad mientist, Oct 19 2011 I'm taking bets on how long it'll take His Borgness to find this-- not_morrison_rm, Oct 19 2011 So, it's basically a Global Hypercolour coat then.-- marklar, Oct 19 2011 random, halfbakery
