I use a white absorbent paper bedding in the bottom of the litter box and then a thick layer of hay as buns love to eat hay when they pee and poop, this is also how I litter boxed trained her. anyway I empty the box every other day as my little girl is a clean freak and if the litter is not fresh she will pee next to the box to let me know it’s time to clean it. she only did this twice before I figured out thats why. It is best to still have some type of absorbent under the hay, unless you use a litter box with a mesh screen for the pee to drop down, also never use cat litter, I use only bunny safe absorbent.

Hay is pretty good litter/bedding. I use it exclusively, bc I’m too worried that they would eat anything else and get sick. The hay seems to be more comfy than pelleted litter, too. The downside is that hay is not very absorbent at all, so must be changed very frequently (as in once a day/once every two days).

I wouldn’t use hay as litter because it isn’t absorbant at all. You could always layer it over something else (wood pellets for example) but I wouldn’t use hay alone.

I thought I would just add another vote for not using hay alone. Just this week I decided to give my buns a plastic container with some hay to see how much more they might prefer to eat hay that way instead of a rack. My buck didn’t use it as a litter box but my doe did. Even in the short time she did it was pretty gross.
