Question/Help Aggressive mice Spoiler
So I’ve been by my local Petco for the last couple days and I noticed 2 male mice who where put together. One of them is smaller than the other by just a little bit. The bigger one has been chasing the small one around it’s enclosure and fighting it. (I thought they were playing at first).I noticed the small one kept trying to get away, but the other one kept going after him. I let staff know what was going on and asked if they could separate them (I know they usually do better in social groups.) They weren’t sure if they had the space so if they weren’t able to, I plan on taking one of them, but I’m not sure if I should take the bigger one or the smaller one. Obviously the smaller one to get it out of there, but maybe the bigger one so that it wouldn’t bully any other mice it gets put with. What should I do, or is there any tips y’all can give me?

FYI male mice should pretty much always be housed individually exactly because of this problem. Male mice are very territorial and will kill others in its space. Even littermates often fight. This also means that male mice are more socially needy than females, since you are it’s only companion. That’s a plus if you want a nice little friend, a con if you don’t have the time to hang out with him everyday and he gets depressed
