Barbi Brown's Bunnies answers the question
ARE RABBITS SMART?
Wait until they train you and you'll know! It takes very little time for a bunny to figure out what they can get away with which is why it is so critical for rules to be established early and to be consistent with discipline...just like children.
Their intelligence is the biggest reason that I don't recommend giving a new bunny too much freedom right away. Not unlike a teenage human, without limits they can become headstrong and get into trouble. Establish yourself as the "alpha" leader and don't be afraid to show some "tough love". See the page on Discipline.
