I think it varies a lot on the rabbit, they can be anywhere on the scale from almost wild to as happy to interact with people as a very interactive domestic. But I agree everything to the extreme - he runs fast, he jumps high, he digs, he chews, and he alternates between doing incredible clever things and very stupid ones :lol:
You'd need a room not a cage, and it would have to be very bunny proof - you probably shouldn't be too attached to your walls/door frames. Doors and windows kept shut and stairgates need to be dog height not toddler. Scamp lives in the kitchen and I follow him around constantly whilst he's out exercising because otherwise he's digging carpet, making tunnels through the curtains, climbing bookshelves etc. he thinks nothing of jumping 4/5' down off the top of something or over the top of something.
He is wonderful though, and very affectionate, he'll flop on my feet for nose rubs (after we've chased round and round and round the living room) and be back up for more chasing five minutes later. He's fine with being handled/picked up. Will let me put a finger in his mouth to scoop out whatever it is he shouldn't be chewing etc.
I'd meet them if you are interested, it's like any bunnies really it's down to their individual personality.
