Rabbits are VERY social creatures and rarely are all that happy ontheir own (although most humans can't tell how well they weredoing until they actually see themwith a companion).
But. They don't necessarily have to bond with another bunny. They need a friend/mate, be it humanor another animal. (Lots of stories ofbunniesbonding with cats, dogs, guinea pigs and in the wild, even deer). A bunny alone will even bond with a stuffed toy (although that's desperation and never very satisifying I'm sure).
I'm bonded with Pipp, and we're together pretty much all the time. She sleeps with me, we have long pet sessions, we play together... (well, I type, she plays on my lap). My bonded pairs, Dill (who has also bonded with me)and Sherry, and Darry and Radar, stick to each other like glue.
If somebody isfinding it hard bonding a bunny to another bunny, it'sa good bet the bunny already thinks its bonded to the human and is being territorial.
