You will get a lot of different answers on this depending how people house their bunnies. Indoor, outdoor, a combo, etc. My bun is an indoor/outdoor combo who i just finished potty training and was rather easy using my method. First off whatever method you end up choosing, find where you rabbit goes to the bathroom, going off mine they seem to like to pick corners, move your litter box to the corners it pees/poops in. If you need to make two for now make two.
For me I use a combo. I use So Phresh brand(any brand should work) softwood(kiln dried so it's safe) on the bottom, as it absorbs the most, I then use the same brand Aspen as it has a stronger odor smell keeping away the urine smell, but it doesn't lock in moisture as well as the soft wood. That goes in the middle. I then top it with hay as rabbit's love to eat where they poop/pee but know not to eat the soiled hay. You could also put a feeder or a hay box by their litterbox so they can eat and poop without wasting hay. My bun will not poop/pee in its cage with wood bedding, or it's dig/rest box i made and will only poop in it's litterbox. Just follow where it goes and it should make it so much easier. Ill post what I use and how my set up is below.
These are the woods I use.
This is how the litter set up looks with all the mixed woods and hay. I have to change it every 2 days. You can see the soft wood doing it's job soaking up all the pee, while the aspen wood stays dry covering the smell.
Her old cage attached to her pen, she will not poop/pee in, as she understands it is her "room."
I started like this with two litterboxes(made from shoe boxes lol) and once she got the hang of it, i turned the other one on the left hand side into a dig/chill box and got a permanent plastic litterbox(posted above)
So you can use bedding and have them not use it as litter but actual bedding it just takes some work and mostly covering all your rabbits pee/poo spots with litterboxes so they get the hang of it. You can do pure litter mixes or litter and hay mix to see what your bunny prefers. Hope it all goes well.
