Mice fighting- blood shed
I have 2 pet male mice, and yes I know males tend to fight more often then females, but I'm not sure how to control their fighting? A few times they've shed blood and have become not-so-healthy? due to this. The main problem is the wheel, so I've tooken that out a few times, but they still fight. It's kinda starting to really worry me- I've even seperated them (I have a 2 level cage), but they do try to get to the others half. If anybody has any tips or suggestions..? that'd be great, thanks!
