I suppose I could have just Googled it, but this is much more fun

Has anyone seen long haired mice? Do you breed them? I've never seen a long haired mouse in my life and there has been one at our local pet store for the past month. I've wanted to buy it just to have it, but I really don't care for mice, I breed rats because they are much easier to care for and they smell a lot less.

I was just curious! She's so cute with her long black hair! I wish rats had the variation that mice do!
