Well as I said in my other thread, my female mouse that I had suspected to be pregnant due to a sudden weight gain dropped 12-13 babies today. Then my friend came to my work and asked if I wanted free feeders. I said "of course" and asked why. She told me her female mouse had given birth to a litter today. She had been unprepared for their arrival since she thought she had two females. (she keeps them as pets). I told her I'd take the babies once they were weaned to use as breeders or feeders depending on which I needed at the time and that I would give her a female mouse in exchange for her male, that way she'd have no more litters popping up unexpected.
