Hi! I am new to this site. I am having the same issues with my piggies not getting along, all of a sudden. They are both female. I got them at 4 weeks old. They have been in the same cage this whole time. I have had them for about 5 months. Im guessing they are around 6 months of age. The past couple of days have been so stressful. I purchased a new habitat for them last week to give them more room to play. Prior to me putting them in there, they started chutting and making weird noises in the cage they have been in all along. All of a sudden, they reared up and went at it. I was able to break them up however this has never happened before! They have literally grown up together and I don't understand. All of the research I have done, it points to one or both being in season. The new habitat I purchased has a divider so I have them in the same area but separated. They can see each other through the "cage divider" and when they meet face to face, they sniff at first, almost kissing which is cute, but then the chutting starts again. I kept them separated all weekend, as this behavior started Thursday night. I tried reintroducing them again yesterday afternoon and after a couple of quick bootie sniffs, they were right back at each other. I have them separated again however I am so upset! I never thought they would get nasty with one another and I am wondering if this is going to be a permanent thing? I am not sure what to do. Can someone please point me in the right direction? I feel horrible they are separated! Please help me get my piggies back together.
