I walked into the garage(which is heated) where my last two female mice are. I haven't been breeding, just keeping about 4-5 females on hand in a 10 gallon tank with food, water, wheel, bedding, and the plastic igloo houses.

I went out to say hi today and give them some food...and one...was eating the other one!!! I was just like..oh my gosh!!! I didn't really know whether or not the other one had died from some illness or what, but the cannibal mouse was killed with a pellet gun to the skull because I don't know if they were both sick or what, but I don't want to risk anything becauase I have 4 pet rats.

Does this happen often?? Why would this happen!? I feed them lab blocks everyday, along with fruits and veggies...Are mice just cannibals!?

I'm thinking back and we had one or two "escape" I'm really hoping I'm not going to find dead little mouse bodies under their bedding!
