Are most pet rabbits happier in pairs? Or do some prefer to go solo?

I'm pondering whether to find a partner for Toby, a neutered male, 2 years old, who I adopted from the animal shelter a few months ago. He is a free-roam bunny who seems quite happy in our home. But perhaps he would be even more content if he had a rabbit companion. Unfortunately, I have no way to ask him this question.

Curious for feedback from those of you who have lots of rabbit experience. Do you think that most rabbits prefer to have a companion? Or are some content to go solo?

Oh I have definitely had a few rabbits that prefer the company of people to that of other rabbits. I have one boy like that right now. He's an extra small netherland-dwarf and so he doesn't like rabbits that are bigger than him, which excludes all other rabbits. He's nice to them but it's obvious he feels uncomfortable. On the contrary he loves people and if he doesn't feel like he's getting enough personal time and attention from me or my sister, he gets depressed.

Although I have also had a lot of rabbits that are really grateful to me and become more affectionate after getting them a companion, so it varies from rabbit to rabbit.

We have had some that would have fought with a rock--depends on both the rabbits.

It always depends on the rabbit, and their personality, some rabbits are happy for your company, while others will get overjoyed with a new bunny friend. One rabbit I had, did not like other rabbits company, she was very territorial, and she only accepted me. The next rabbit I had was much the same, except she was more of a gentle soul, so she would tolerate other rabbits for a time, but then out they went. This Bunny I have right now, her name is pepper (Profile photo), I haven't tried her with other rabbits, but she is even more gentle than the second one, so I'm not sure how she would be with others. All three of my girl rabbits have come from the same family line. So yea just get to know your rabbit. You can try it and see how they respond, some rabbits just are happy having you as company, while others really need another bunny friend.

I'm definitly in the "rabbits should have companions" camp. Granted, there are some that might be happy enough alone, or have real social issues, but the vast majority is not of that kind.

More often than not, I suppose, it's us humans messing things up. Not many have the resources to let the rabbits do their thing.

I started off keeping rabbits like my grandparents did, single, tiny hutches. Myxo struck, and the sole surviver was Fury, sheltered in my kitchen for 8 months...
I learned a lot during the past 12 years.

Males can be reasonably happy alone, even intact ones can make great free roam house pets. Herr Hase seemed lonely though, so I got him a doeling, Dotty, spayed as his cuddlebun. Do not recommend if you don't have cheap, washable furniture and PVC floors, the spraying got out of hand. Well, he got sick, and his successor continued with those antics -I rescued another buck and Pacino, my house bunny, got the snip - what a relieve. no more spraying, no more pestering Dotty for hours.

My breeder girls are another story, I usually keep a daughter to live wih mom, and I retire them from breeding at 5-7 years. Right now there are two seniors, 5 and 11yo, and just one 1yo doe because my favorite managed to run into a car . They all live together, and by now I can't imagine it any other way.

All that grooming and intimacy, and the shared lookout when on the meadow, or piling up in questionable comfortable positions, caring for kits and raising them in a social setting (I'm pretty sure one doe even started lactating even though she didn't have a litter), it's just amazing and it makes things so much easier if I let them work together.

I live alone, and just watching them having something I'll never have, participating, makes me feel a little better

I mostly skiped the bonding issue by keeping the doelings that get along with everyone, so, little experience on that.
