Hi. We have boy and girl lop eared rabbits. They were happy together initially until both had ops (both neutered) and we then found it difficult to put back together. Now they are 20 months old and we have built a large cage with the old hutches placed in it so it is more or less open space/neutral territory (which we were not able to do before). They managed an afternoon, evening and so far all of today. However I have noticed the male trying to hump the female from the front - the female then just runs off as if to say 'no way'. Is this worrying behaviour - it doesn't seem to be particularly aggressive. Before, when we did not have completely neutral territory they began to do this and fight - we are just worried about them getting hurt.
