She and Freckles were out yesterday evening for a rebonding session, using the x-pen I set up in my living room. She and Freckles had lived together for 4+ years until Missy got sick last summer. Freckles decided at that time that she preferred to live alone.
While Freckles may prefer single-life, I know it's not best for them. They both are lonely and need the company and comfort of a friend. Bunnies are happier in groups. So, the last week or so I've been setting them up together in the living room to see how things go. They're making progress, but Missy still tries to bite Freckles when Freckles won't groom her. With time, it will get better and they'll get along again, I'm sure.
Missy's way of dealing with the discomfort of being forced together with another bunny is to try and escape from the situation and get herself into trouble in the process. Where she thought she might go once over the fence is anybunnies guess!
