There are a number of other materials that are more suitable for use as rabbit litter, such as:
* Paper pellets: Paper pellets are made from recycled paper and are very absorbent. They are also dust-free and biodegradable.
* Wood pellets: Wood pellets are made from sawdust or other wood byproducts. They are very absorbent and have a natural odor control.
* Hay: Hay is a natural and inexpensive litter material. It is absorbent and provides rabbits with something to chew on.
