Every now and then I find a mousie at a pet store that I like; usually they don't work out for breeding for one reason or another. I do have two does bought from Petco a few months ago, and they have produced a litter each off of a buck bought from a reptile store. He was so nice and big and had fairy decent ears and tail, and he's the sire of those two aforementioned litters.
My tri and splashed mousies started with three acquired from an East Coast breeders almost four years ago by way of mousie train via Rodentfest that year. Since then, there has been little outside input, but since i have a large mousery, I had many, many options to prevent the line from becoming overly inbred.
There will be some inbreeding going on in my attempt to recover a line that was almost completely lost, unfortunately, several months ago. I'm hoping the remaining meeces in that line carry the full complement of genes necessary to give me back my fawn satins.
