I'd look at the animal shelters in your area (no kill of course) because many of them take in everything from ducks to hamsters to rabbits and reptiles, not just cats and dogs! Hopefull your aunt will take her in though, or a friend or another family member. Sorry the sneaking in didn't work... I remember when my roommate snuck a kitten into my college dorms, lol. They were so oblivious with a huge crate and carrier and the MEOWING as we were walking through the front door, so I'm surprised your landlady saw the rabbit. Maybe you can discuss a larger deposit in lieu of her allowing you to keep the rabbit?
