[QUOTE="jnowack, post: 372153, member: 3954"] The rat tails don't do well in the cold. It is caused by interaction of different gene pairs. This article says that they must carry at least one black gene and be heterozygous at the other locus (I assume this is the locus where the rat tailed gene is located). This article does not talk about the diluter gene, but I was told that they had to carry a diluter gene also which would be a third locus. I have never heard of a rat tail that was not grey.
