That is a good question. In general, it is thought that rabbits are happier in pairs then alone because of the fact that rabbits generally live in colonies of bunnies. It makes them feel safer to have someone else around to “keep watch” as well as to groom them, snuggle with them, and play with them. With rabbits however, the introduction can take awhile, and it can be days, weeks, OR months before two rabbits can live together all the time unsupervised. I was fortunate enough to have two bunnies bond in a couple hours, but that is not normal. I’d recommend as a first step taking your bunny to the local rescue, and having him go on some “bunny dates” where he can meet other bunny girls (or boys) and see how he interacts with them, and if there is a special one for him. There is a lot of information on this site about “bonding” (the process of introducing two bunnies), so search that in the forums, or up top in the Bunny Info. to see how it works!
