All it takes is some bunny proofing and cleaning up. Just like you would with a puppy or baby.
Rabbit pee stinks. So does cat pee. All it takes is regularly cleaning the litter box, and getting them fixed helps a ton.
Most rabbits will live a much better life inside, protected from the weather and predators, where they can run, exercise, bond with you, and explore, rather than being locked in a tiny hutch their whole life then dying. Especially with so many predators (which could kill them just from scaring them and causing a heart attack), and heat (which kills rabbits all the time) and all the other issues.
