Well, today i was cleaning my mice bins and there was a dead mouse buried under the bedding rotting Im surprised that I did not smell it... Until i uncovered it! I thought I was going to puke, This is the second mouse ive lost this week( I think to old age) but if i have another one die soon they are all going to the co2 chamber. I cant wait until my female mice im raising from my own stock are ready to breed!
