Okay my little girls are just turning 6 months old in a week and at night they chase each other around the cage and humping each other. Last night they got a little aggressive while doing that and i made a divider so they can see and touch noses but thats about it and i am only going to put that in at night time because they have been keeping me awake for the last 4 nights. Now i am raising the money to spay them, do you guys think that would solve that issue or could it be something else? Also i know i am only putting the divider in at night but is that cruel? During the day they are fine with each other they are sisters so they bonded pretty well. Thank you for helping!
