I have a female spayed mini lop for about four months now. She has proved to be quite a test on my patience but I'm really trying my best to keep her. She has started thumping loudly in her cage either in the middle of the night or early in the morning. I cant figure out what would be bothering her so much and I need help to make her stop. Once she starts her thumping fits she wont stop even when given food. I usually have to put her outside in her carrier until she calms down. She doesnt do it everyday but its at least once a week. Anyone else have this problem?
