What does the satin mean? I absolutely love these mice. They are regular pet store mice. I actually got them from a store that specializes in reptiles and these were meant as feeders. I'm hoping I can start handling them soon (don't want to stress them out too much) so they become more comfortable with being handled. The buck, once I got him into my hand was very content to sit in my hand and check out my fingers, even cleaned himself a bit. He's very cute. And I love the two does. The other female looks like her hair is not as long and its smoother. So would she be a blue? She's the exact same color.
