Mine have big cage + pen areas, and they come out for extra exercise under supervision. I’ve “bunny-proofed” the living room for them and all wires are protected. It only takes a little nibble on a wire and you’ve got a dead or seriously injured rabbit, so I’ve never relied on training or distraction.
I do provide plenty of appropriate things to chew but they can be like children in the way they prefer things they aren’t allowed, so I find it easier just to remove anything I don’t want used as a chew toy!
Litter training is easy because they pretty much do it by themselves. They like to eat and pee at the same time so all I did was line a box with newspaper then add newspaper pellet cat litter with a lot of hay on top. They go in there to eat and they’ll pee in there as well.
They do leave a fair amount of poo outside the litter box but it’s tiny dry pellets so no big deal. They just sweep up. But for pee they like to go in the same place on a soft surface and they take to a box as easily and instinctively as a cat does.
All bets were off after my boys reached sexual maturity though (before they were big enough to castrate). They lived in neighbouring pens so they didn’t lose their bond too much and they’d flick wee at each other and mark along the boundary with the other pen. It took a few weeks after neutering for the hormones to calm down and cleaner habits to return.
My girl has always been perfect apart from a single pee outside the box when she first arrived as a young but sexually mature adult. (She’s spayed now.) And I’d say 80+% of her poos go in the box.
