Well, I have good news! Not only are the 10 pups from Christmas morning doing well and nursing, but my other set of mice had babies while I was at work! I checked on both sets of mice, and I was surprised to see more babies! Pretty exciting, actually!
The newest babies (Born Dec 26, 2005):
The first litter of babies (Born Dec 25, 2005):
Looks like only 4 in the second litter, while the first litter had 10. The second mama never did look very plump anyway, so maybe I'll keep her off the breeding schedule... I'll be transferring the babies and mommies over to a large Kritter Keeper in a couple of days, and clean their birth cages up.
