When I brought my girls home, they were together 24/7 for the most part. I gave them a bigger cage and all of a sudden Daisy's gotten somewhat territorial over her log hut and Millie is sleeping in her pouch at the top. Every day around 5 or 6 AM I wake up to find them wrestling and squealing. The litterbox has been moved to Daisy territory because that's the only place anyone will go to the bathroom in the cage - and almost every time she goes down there, Daisy wrestles Millie. She is mostly the instigator. This morning she climbed into Millie's pouch to get her up from sleep and it pissed Millie off so much that she got out and chased her. I can't tell if this is play or real fighting. When I come to break it up they come to me and snap out of it like nothing ever happened. However, I'm kind of bothered because they used to sleep next to each other and groom each other all of the time and now they sleep separately. What's going on now?
