Hey guys, my two little baby girls(even though they're almost 2 months) have been showing a lot of agression towards eachother. The mother also lives with them but she really wants nothing to do with them as she minds her own business. Now somtimes they are okay with eachother, but other times they constantly show teeth, make a weird sound and just stare at eachother. Then the next day they'll be find. Then in a week they'll do the same thing. The only time that I saw them fight was just once and they quit it after a couple seconds. I'm just a little lost on their behavior. What could be the cause ? The cage has more than enough room, more than enough shelters, food,water and hay.
