Ohhh yeah, i saw that at a pet store, it was like a horror scene, all the mice were trying to breed with eachother and they were all coverd in blood,(so were the walls of the tank) and the....."boy parts" on the males were all chewd up.Appantly those females were NOT in the mood for some luvin.

I asked the person who was working why the mice were being kept like that and why they were on display/for sale when they all were obviously injured and he just replied...."Hey Dude, thats nature mice like to #%&!" I was so furious, i didnt even know what to say to that.
