lol, we think she's isn't wrong.
I stumbled on this by accident - when I was a teen I had 3 mice; 2 females and one male. Man were they busy. In a short while the population had grown to 40. The cage was full, then the population dropped off but you could see the little critters mounting each other. I ended up taking the whole crate cage to the vet to find out if they were slowly going sterile or something. It was 'or something' all right, lol!
Those boys were busy little sodomites.
...I wonder WHY?
