I have three bunnies who live happily together.
Originally I had two, then one died and I went to a rescue centre and bonded the remaining one with another. I started volunteering there and rescued another three - who were slowly introduced to the two and got on fine. Then I fell in love with another and gradually bonded him to the group. Last year I sadly lost three which leaves me with the three.
Whenever I introduced a new bunny or bunnies to the mix I always did it very slowly and in stages. In the case of the last male to be added it took a good few weeks before he was fully part of the community.
I have eight cats and they get on fine with the rabbits. I've never had any problem at all.
If finances permit I am hoping to get another pair or trio later in the year and fully intend for them all to live together, but won't rescue any until I have the time to spend supervising their bonding. I love watching a large group of bunnies playing together but think it's important they have sufficient space to have their time alone if they need it.
I think you will be fine bonding three together so long as you have lots of patience
