There will always be orange meeces in my mousery; one of my early goals was to breed healthy satins and fawn satin was one of the two colors I especially wanted, the other being champagne. I may eventually stop having the Big Fat Mousies. Using Avy means there's a real good chance that any mouse from that line will grow into a real porker. I'm weeding that out in favor of recessive yellow, which gives a nice deep orange without the obesity ,most, if not all, of the time. Having my nicest fawn and red tris grow too obese for breeding has been a real hindrance to improving the line.
I still think the fat orange mousies are cute, though, and so nice to handle, especially on a cold winter day. There's just something about the sleek shiny coat over all that soft mouseflesh that's just luscious to behold.
Thanks to both of you. There actually was a little space between the edge of the wheel and the tank; the girls shifted the wheel squeezing through that gap and now there's more than enough room. I love these big wheels for two reasons: 1) it doesn't cause the tail to get twisted back behind the mousie over time, as they try to keep their tail from dragging and 2) It's wide enough that two mousies can run side by side.
But about the curly-tail thing.. I have a mouse who has that though I have no clue why.. he and his brother (who live together) have always had one of the big wheels. It's kind of bizarre. I named him Curly because of that. :X
Some of the weird things that appear in meeces are just genetic oddities that aren't transmissible. Like the odd-eyed boys I have. A crooked tail might be a case of the mousie carrying the gene for taillessness. I had a mouse with a zig-zag taill just like The Brain from Pinky and the Brain; he was PEW as well. It was quite funny!
I guess the pix don't really capture the reason for the name except for the flat ears. He is quite wide from side to side but relatively shallow from top to bottom. That combined with his semi-long hair makes him look like he was sat on or something. He's one of the calmest meeces I've ever had. when I pick him up he just nestles down flat to my hand and vibrates. He sleeps a lot, often doesn't stir when I turn on the lights in the mousery, doesn't move until I open his tank, and sometimes not even then. He does wake when I put the food in, though.
