On feeding night a few weeks ago I was grabbing some feeder rodents, and I noticed that two mice in one of my litters had much shorter tails than normal. When I saw the first one, I initially considered the possibility that another mouse had bit its tail off. Then I saw the second one and gave them a closer look. There were no indications that they had been attacked, and it became apparent that this was something genetic. I decided not to feed these two mice off, and see what happens when I breed them back to each other. Luckily enough, one is male and the other is female. I was curious who's seen these stubby-tailed mice before, and how common it is.
