I had a rattie a few years ago. A female that was as sweet as pie. She never ever bit. Not even the dog or cat. She loved everyone and everything. I had had her since she was a baby. She would give kisses and anytime you would pass her cage she would reach out her little paw and grab for you to pet her or pick her up. I had always been weary of rats until her. Now I would get another one in a heartbeat but my hubby doesn't like them and my girls (cats) would go mad trying to get to her. For me I would want another female because the experience I had with her was amazing.
