Ninety-nine percent of the time she and her "sister" are in the house with us or on the porch with us. The only time they are in their pens is when they're feeding so they don't fight over food.
A towel might be good, but as we are still trying to housebreak her, she would only use the bathroom on it. Not to mention, rabbits eat everything, including towels, which would seriously harm them. We've only had her a few days, and she had been moved around a lot before we got her, so she is still getting used to us. I assure you, she gets lots of love and attention. We are planning on getting them both a no-chew mat to lay on.
