You've found your bunny expert help, now we're going to talk a bit about your part in all this.
The most difficult part of the whole bonding process, according to Edie Sayeg of the Georgia House Rabbit Society, is helping the humans remain patient and learn to think like a rabbit.
Bonding rabbits, even rabbits who like each other, can take a long time and much patience. It is important to go slowly, and follow the lead of the rabbits involved.
Sayeg suggests that the first meeting be at the shelter or rescue organization so that it is completely on neutral, not home territory…that makes a big difference. Also, if you have access to more than one rabbit to meet, your chances increase in finding the right rabbit - a new rabbit who is compatible with your bun. If this is not possible, you must be aware of the possibility that trying just one rabbit may not succeed in a successful bonding. Following the process outlined here will still give you the best chance for success, even though your rabbits didn’t have a pool from which to choose a bond mate.
Bonding rabbits also absolutely requires that you are willing to watch them both carefully and learn their body language. You may learn quite a bit about a rabbit you’ve been living with for years! It can be a tremendous experience, and really bond you with your rabbits as much as you end up bonding them.
Be patient. Be calm.
Rabbits are very sensitive to frustration, anger, or aggression. If you’ve had a long terrible day, your head is pounding, and this daily bonding thing is just one more thing on your list of 32 things you need to do before you can finally get to bed, skip it. Not a good time to do bonding.
If you feel like you are not getting anywhere with the bonding, or it has become dangerous, get help from a knowledgeable rabbit person with specific experience in bonding. You may even be able to find someone who will council with you over the phone on facetime – keep trying with different rescue groups close to you – names are available at The House Rabbit Society.
