I have a brown Lionhead bunny (brown). The pet store said she was 3-4 months old and today I bought another lionhead (black) and she is 2 and a half months old. They are hopping around on the floor and playing. I was wondering how long it would take before they can be in the same cage and how to know they are bonded? I got another because the first one was not very social and I just found out that she had a sister with her when she was recued. I fell inlove with the second as well. They are pefect.
