and this…. OMG

Link to pic

From what I've heard they get sick rather easy and don't live that very long. A dutch girl I was in contact with had one of these for about 6 months, then it died. From what I understood it's some genetic "flaw! that they've bred on to get them naked. Some of them lack eyelashes and whiskers aswell.

The one in the picture looks healthy and does have whiskers so I don't know if they've "perfected" the breeding somehow.

Pehpsii, maybe you can translate my article about hairless mice?

I guess they´re similir to hairless rats or guniepigs (marsvin) but hairless mouse are uncommon och havn´t get that far in development..

Guess U have to breed naked to one with hair so that there health improve like guniepigs (i can´t spell to that mammal) they have a seperate breed of guniepigs that called lakeland to improve the naked once..

guineapigs (=

The second picture is hairless (hr/hr). The babies develop fur, but they loose it all when they are still very young, like in the second picture. Maybe the mouse in the first picture is hairless too, but it is possible to breed fuzz so that it looks hairless (fuzzy hairless). The 2 people in Holland I know who were breeding hairless, quit breeding them because of health problems. I don't have scientific details on them, only what I have heard from those two breeders. One of the hairless mice even became rhino, and got severe eye problems. I hope Dynamimaus has more luck with them!

There is also fuzzy hairless (fz/fz), fuzz bred to be as hairless as possible, and they were very hard to find over here (Holland), and the ones that were there were not very healthy. But some breeders are breeding them to a better health. They don't develop much hair so they can be distinguished when they are babies, when other babies get their hair they hardly get hair.

In the Dutch standard there is also a hair type called "rex" (very confusing, since they gave the name to mice with a coat that is very different from astrex and has nothing to do with astrex). That looks like fuzz with a bit more hair. Genetics are unknown for this type, but I suspect it is possible it is fuzz, bred for more hair (as far as I know, no breeder has tried if "rex" is actually fuzz). But this is only my suspicion, most people over here think it is different variety genetically.
