Will my pet female mice learn to like each other?

Question

I bought a female pet mouse about a month ago and was really happy with her. She loves running in her wheel and started rearranging the fluff in her cage the way she liked it. The girl at Petco told me mice do better with companions or they can get depressed so today I bought her a little female friend. They sniffed each other and seemed to be fine but every once in a while I hear them squeak and they look like they may fight. My original mouse seems to avoid the new one and appears scared. The new one has taken over the wheel and squeaks whenever the first one tries to enter the little hut in the cage. Will this pass? Are my mice not compatible? I don't want my original little baby to feel uncomfortable in her home - I wanted to get a her a friend to make her happy! What can I do?

Answer 1

It sounds like your mice are just developing a pecking order.  I've owned mice for the last fifteen years and this happens some times.You didn't say how you introduced them, if you put your new mouse into your original mouse's house then that can cause fighting.  Although mice need friends, your mouse has made the house her home and will have scentmarked the whole place, so when you have introduced the new mouse in it's caused an upset. Like if you were sitting in your house watching the tv and a complete stranger came inside and started making themselves a coffee or something.  Your best bet is to seperate your mice for a few hours, clean the cage/enclosure out really thoroughly replace all bedding etc, then introduce them together again.  Female mice will rarely ever fight much, most of the squeaking you'll hear is just your two girls working out who's on top of the pecking order.  You did the right thing getting another mouse, a life of solitary confinement isn't much of a life at all!

Answer 2

I think that you should have gotten a male mouse the second tie because it seems that them being the same s*x will result in fights.

Answer 3

Well I don't know about mice, but I used to have 2 rats (FEMALE) and they faught for about a week, and then they learned their going to have to be stuck together so just keep a close eye on them for awhile I took a piece of cardboard and I put in the middle of the cage but then they chewed through it. But whatever works best for you! ;)

Good Luck!

Answer 4

i had two mice before and one killed the other, and then it died

Answer 5

Oh gosh, they sound the same as mine. We thought they were okay at first, but then we started hearing a lot of squeaking. It eventually got worse and one bit the other and made a hole in her back and ear. One seemed to be really aggressive and would hog the wheel, the food, etc. and would attack the other one for no reason what so ever. I suggest you observe them for a couple more days and if it doesn't get better, you should separate them before it gets messy.

Oh, the pet lady ALSO told us that they would be fine together too. She was oh so wrong.

Answer 6

female mice should naturally like each other anyway its very very rare that female fight try introducing them to each other wen u clean the cags out and go from there

Answer 7

I used to have two mice, they would fight at night until one of them killed the other one. Now I dedcided that mice was the wrong way to go so I have a snake that eats mice, I guess that's my revenge against the mouse that killed my favorite of the two... I never really thought about it until now.
