First off, I am new here. I am also a new bunny owner as my daughter showed up one day with her rabbit, Sophie and all of her belongings. It is a really nice cage for her with an attached run area, but as a single bunny, she is lonely. The first thing she does when we let her out of her cage/run is trot promptly into the living room and pee and poop on the dogs bed! Then she will go back as many times as we allow it and do it again and again. But Sophie has seemed to take a liking to playing with our Rottweiler mix, Lucy (also a dump on Mom and Dad by same daughter) (but we wouldn't trade her for anything, lol). When she is playing Sophie makes some strange "huffing" noises. I need some of you bun experts to tell me if this is playing or Sophie is mad. I wouldn't want to stress her out but she starts this every time we go out to sit. Sophie was purchased from a pet shop and not only do we not know her history other than she was returned twice before my dtr got her, but we don't know how old or anything else about her. Note: I live in the country and have 5 acres, I don't put her out in a pen as we have coyotes and other animals that would love to eat her.
