Hi, and welcome to the forum :thumb: I would wait until at least 6 weeks until after her op to try bonding her, to allow her hormones to subside. I would recommend going to a rescue to adopt a partner for her, they will most likely have several rabbits suitable to try her with, and some rescues have a bonding service too. If the bond was unsuccessful, at least you would be able to try another rabbit with her. I would recommend a neutered male as the most suitable companion.
