Rabbits are very social and I think nothing can compare to two bunny companions. It is true that you can provide interaction and stimulation, but you will not always be home and available to hang out with your bunny. Some days, weeks, or months are going to be busier than others. If you work outside your home or attend school, that is a lot of time that your bun is going to be by himself, not to mention your other family and friend obligations.
I had a single rabbit a couple years (before he passed) and he seemed happy and content to me. And then I got Meadow and she was a single bunny for almost a year before we adopted Max. Having a pair now, I would never go back to only having one. It’s amazing to watch them “talk” to each other, they give kisses, they snuggle. They really are best friends. They don’t spend every waking (or sleeping) moment together, they will go do their own thing, but they always come back to each other to “check in”. They are less destructive: some of this is due to them getting older, some of it is due to them keeping each other company (a bored, lonely bunny is *usually* more destructive).
There are factors to consider:
Do you have space for two separate rabbits until they bond, or permanently in case they never bond? Can you devote time to the bonding sessions? They may bond in a week, or it may take several months. Until they bond and possibly after, it is likely that one or both rabbits may lose their good litterbox habits and leave territorial poops around the house. Both rabbits need to spay/neutered. Adopting from a rescue is your best bet for getting a bun that has already been altered and they will sometimes allow you to take your bun “bunny dating” so he can pick his own mate.
Money is an important factor. Two rabbit cages and double supplies until they bond. Double veggies, hay, pellets, litter. These are not that big of a deal if you are already buying food for one rabbit. The major concern is DOUBLE VET CARE. Vets do not give a “buy one, get one” discount on their services.
