Number One: Cord Clips/Cord Covers
These two items will come in very handy for keeping your electrical cords away from your bunny's sharp teeth. Bunnies do tend to chew on cords, and there are numerous theories for this, one is that they are attracted to the electrical current, and another is that the rabbit treats your precious cords much like tiresome roots growing through its burrow. Whatever the reason, you will need to take special care to keep cords well away from your rabbit. Run them under the carpets, cover them, or use clips to hold them up higher than bunny can reach. (See 'Indoor Cage Options" for link to getting cord covers in 10' lengths cheap!)
Although the most persistent bunny can chew through most cord covers unless it is PVC piping, we have been using this type. We got 100 feet an it has been all we needed through 8 bunnies.
The item description is still good if auction has ended. Another one starts under same description and price.
Item Number Two: Houseplants
Most common houseplants are toxic to bunny, so make sure that they are well out of the way. On counter tops, desks, wherever your bunny cannot reach them. Unfortunately rabbits really have no idea what is good for them and what isn't, so they tend to just chew on anything that they come across. Save your houseplants and your rabbit by keeping them well out of one another's way.
Item Number Three: Exits!
Although you are giving your bunny some serious freedom, you will also need to make sure that there are no easy access exits available to him or her. Pet doors, and doors that open to the outside should be closed and carefully watched if your bunny is in a room with them. Ideally, having a door between your bunny and the front door is a good idea.
Item Number Four: Litter boxes
Your bunny may return to his or her cage to do the business at hand, or it may seek out a quiet corner. Make sure that your bunny always has the litter box of their choice available to them or you may discover that bunny has picked your carpet as a new litter box, which is most unpleasant indeed.
Item Number Five: Space
How much space is too much space? You might want to consider only letting your rabbit have the run of a room or two. Having unsupervised run of a whole house, especially if you have an active family can be disastrous for bunnies who have a natural tendency to both get underfoot and streak across walkways with little to no warning. Either have a more contained area for your bunny to roam in, or ensure that you always supervise your rabbit when it is out of the cage.
