In my opinion mice are the most precious, precocious and humble little animal in existence. I love their little hands and toes, the nearly translucent ears..everything is so perfectly tiny!!
Anyhow, in a lab setting I learned a few things about mice I never learned from my pet mice....
Lab mice rarely or never bite, even when they are having blood drawn.
Lab mice caged with other mice of the same sex have active sex lives with each other; females mount other females, males mount other males.
Many a lab mouse fathers help deliver babies. They lick the mother mouse as she delivers and rolls the babies in his paws licking them clean and tucks them under him keeping them warm and out of the way while mom pushes out more and more babies. With pet mice, we took the sires out of the cage because we were told they may eat the babies. I have seen pet mouse mothers devour whole litters, but in the lab setting, dealing with hundreds of breeding pairs, cannibal moms were a rarity and I never once saw a cannibal father.
Lab mice remember each other. A mother and daughter housed together after being separated at weaning groom and play immediately, as opposed to two stranger mice housed together, who often keep their distance for some hours.
Anyhow, in my job, I bred as many mice as I eventually euthanized in preparing their tissue for further research.
Mice are miracles. They are the first step in the long haul to human clinical trials. Anytime you undergo any medical procedure, or are prescribed any helpful pharmaceutical remember all the little mice that were first for every trial and error and say cheese...hurray for the little mouse!
Bah, teary eyed again!!
