About 18 days ago my male rabbit got out of his cage and was playing around near my female rabbit’s cage for a while; he did not get in to her (thankfully). But now she is going through a false pregnancy I think....she is pulling her hair out and putting it all in her hay rack (she can get into her hay rack and sit in it). Is a false pregnancy stressful on a rabbit? And should I make a nesting box for her or should I just leave everything as it is and let her make a nest in her hay rack? The problem is that every time I put more hay in her hay rack I would have to wreck her nest. Any suggestion would be great!
