I have two females. One I have had for over a year and the other I just got about a month ago. I already quarantined her and I have tried introducing them and it seems to go well for a little while. Then my older girl always hops on the younger one and the younger one squeaks very loudly. I am always near by with a glove and I separate them immediately. The younger one never has a wound or any bite marks on her so I think this is just the older one showing her dominance. Unfortunately I apparently do not have the will to let them work it out or let her stay on top of her because I get scared when I hear the squeaks and I can't not grab them. It is just my instinct. Does anyone have any advice? I'm honestly at the point where I just want someone else to introduce them because I am a scaredy cat. I just don't want them getting hurt in case she is being aggressive. Thanks!
