Once the rabbit has scented out one spot to use as its toilet it will always return to the same spot. Once you determine the rabbit is using the box you may start handling the rabbit. Start by removing your bunny for 10 to 15 minutes several times a day. You may now leave the rabbit out of its cage for longer periods of time, but watch carefully and return it to the cage if it shows signs of lifting its tail to urinate. If you catch it urinating outside of its cage you can spray it with a water bottle and return it to the cage.
Rabbits love to chew on things.
They will chew lamp cords, chair legs, carpets, etc. I would suggest you rub tobasco sauce on the cords and if you start to see it chew on the cord use your water bottle and spray it. Always put it in the cage. Your bunny may leave some droppings here and there, however, a whisk broom and dust pan will take care of this. Do not leave the droppings on the floor, as this will only encourage your bunny to use this area for its new toilet.
