I have got 2 girl rabbits and 1 has got all of these clues and is growling at me what do I do? It has started to build a nest and I wonder how many weeks are left. it is puling out its fur and all and making a nest out of its fur. It is approximately 1 and a half years old. We split the 2 girl rabbits up 2 weeks ago. I need help I don't know what to do.
