A I would like to have that information myself! As far as we know, there are none. If there were, several breeders would love to get hold of some! There have been unsubstantiated rumors that they exist in the laboratories. If they do, they are a well kept secret.
A Cream is chinchillated yellow (i.e. Fawn). The easiest way to separate the chinchilla gene from the fawn is to breed Cream to Black, then inbreed the F1. If you use Black Tan as the outcross, you can produce Black Fox (chinchillated Black Tan) as well as Cream Fox.
restriction gene plays a part in the American
Berkshire/Cap-Stripe pattern, it would account for the
widely varying patterns, and the fact that I can get one
variation or another from almost any mating as long as one
parent has the markings. I’m still working on this
idea, but for instance, a Berkshire with a blaze and lots of
white could be Hre-H, a cap-stripe with heavy color Hre-h,
and a patched or well-defined cap-stripe Hre-he. I could be
wrong, it’s just a theory. With Hre supposedly being a
homozygous lethal, it might account for why I get more
stillborns when I double up on my cap-stripe or patched
marked rats. Would you consider up to 25% or more babies
born dead or dying at birth unusual, in healthy young rats
that aren’t being bred a lot and in most cases not
involving any significant inbreeding? Chris Faron, Millers
Creek, NCA It’s interesting to hear of the higher incidence of stillborns with your cap-stripe rats. The lady that was working on Capped-Stripe rats here several years ago was the only one at the time breeding them, and I can’t remember if she had the same problems as you are having. It could be a genetic condition as you suggest.
female that has a very symmetrical blue or blue agouti patch
on each side of her head (like a Dutch mouse) and a single
blue spot in the middle of her back, she’s really cute.
One of her littermates, I think, is a pink-eyed or red-eyed
blue, he’s a very light blue with a slightly beige
cast, and a white blaze. What do you call a red-eyed blue
—a pink-eyed one is a silver, right? Chris Faron, Millers
Creek, NC
A The pink-eyed Blues (Silver) are a
totally different color than Blue—an off-white
color with a blue cast in the coat. Your light blue with a
slight beige cast sounds different. We don’t have
anything for a red-eyed blue. Judging by the photos, your
rats with the dark eyes look like Powder Blue or Silver
Blue. Your red-eyed blue is very interesting.
I was thinking, if we put our heads together, we can make a new breed with my Bootiky and Mighty. We need to get the right male with the right genes and we could pull this off. Please write me and tell me what you think. Jacklyn Holt, Enid, OK

It would be very interesting to breed one of your mice to a
male mouse and see what you get. Most likely you would not
get any Tailless; however, it could happen. Your chances
would be increased if you went back to the same pet store
you got your mice from, and found a male that looked
similar. If your breeding did not produce any Tailless, then
you should keep one of boys from the litter and breed him to
either his mother, or to your other Tailless mouse. This
works for Tailless rats, so it should also work for mice. If
you do breed your mice, please let us know what happens.
