Hi. My name is Diane and I just bought 2 mini lops for my children. They are the cutest things ever! The pet store guy said they are brothers and are 12 weeks old. He said they can live together in the same cage. Well, the first 2 days at our house they were great. Snuggling with each other, very friendly with the kids. Then the bigger one started mounting the smaller one, not just once but many, many times. The smaller one seemed scared and tried to get away. He pulled out a lot of the smaller ones fur which was quite alarming to me. The smaller one has a small round bald patch on the back of his little head which is red now. I went out this am and got a second cage to separate them so that the big one stops bullying the smaller one. I am so bummed out. If I get them fixed, how soon can I put them back together? I really wanted a bonded pair and these 2 seemed so perfect. Will they forget each other after a period of time?
