Litterbox Training
Many people are surprised to find out that bunnies can be litterbox trained. Most can be trained quite easily, especially after being spayed or neutered.  Be sure to use the right kind of litter for your bunny, we recommend CareFresh or Yesterday's News. Don't ever use clumping cat litters or pine or cedar wood shavings; all can be deadly to bunnies. Simply line the litterbox with newspaper, cover with about an inch of litter and pile fresh hay on top  - guaranteed to lure your bunny in! Be sure to add fresh hay a couple times daily and clean the litterbox regularly.
