The past few days one of my females is screeching and attacking the other female. They're in a 2x5 cage. It's whenever the ones gets too close, or goes by the water or food. It's increasing in frequency. I was going to split them up but keep them next to each other, I didn't plan on doing that, I had hoped they would get along. I don't want it to progress to actual biting. Has anyone had this happen before?
