"Coat to be as long and dense as possible, silky in texture. Bucks have usually longer coat than does." (Standards for Long Hair.)

"High sheen coat with a satin-like or metallic gloss. White to be known as Ivory and to be as white as possible." (Standards for Satin.)

"Coat to be as curly as possible. Whiskers curly. The mouse's coat straightens somewhat as the mouse ages." (Standards for Astrex.)

Quick Look

Of all the four Astrex varieties (Short Hair Astrex, Short Hair Satin Astrex, Long Hair Astrex and Long Hair Satin Astrex), this tends to be the easiest to breed to meet the standards. This is because the longer hair gives the curls more space to curl and show the curls, and the hollow satin hair curls easier than non-satin hair.

Genetic Background

Long Hair Satin Astrex mice have:

- go/go (or go^Y/*), making them long hair instead of short hair;
- sa/sa, making them satin instead of non-satin; and
- Re/*, making them curly instead of straight.

In More Practical Terms...

In order to get the best coats, the combination to go for is LHSA to another LHSA, or LHA, striving for a coat that keeps its length and curls as long as possible. Remember to keep Astrex-bred Long Hair Satins around so as not to end up with thin coated mice.
