I don't know what other rabbit owners do with their bunnies. But with Erin, she has a good sized cage (shown below) and is litter box trained. She stays in her cage when I'm not around, but when I'm home and can keep an eye on her, she comes out to play for at least a few hours, having run of the house. So maybe you could do something like that with yours? This is just what I do, you should try to get other opinions to see what would be best for you and your bunnies
