Hello guys, I have a strange question. I have two degus, one of them (a couple months older) is a male, the other one was not really identified as the people in pet shop were not sure, but we are pretty sure it’s a girl. They didn’t get along when we first put them together in one cage and would start fighting, but after some time of exchanging them from one cage to another, they became friends and now we keep them together recently. My question is: in last couple of days, the smaller one (a female?) is humping our older degu, which is a male 100%. Is this normal, or is this only possible if both of them are males? Even if it’s asserting dominance, the smaller one should not be a dominant one, right? I am really hoping you can help. Thank you very much, Nem
