I've recently discovered satin in my longhair cats. They are part of a breeding programme and I'm thinking it could be an accumulative gene similar to glitter as I've only really noticed it being very intense in last seasons kitten's, now a year old and the first litter of this season (four weeks old). In comparison to other satin cats I feel mine definitely have a more intense sparkle/shine and you can see some of the hairs actually look quite hollow. Is there anybody that studies this particularly? I will do my own study. I'm just finding there isnt much information out there. It's hard to post good photos but I have some videos that show it very well.Thanks.
