One or More Bunnies?
Rabbits live in groups in the wild called warrens. They interact to raise their young, find food, and keep watch for each other. Single rabbits, therefore can feel isolated if they don't receive enough interaction. Pairs of rabbits will often form strong bonds with each other especially two females, or a male and a female. One study showed that when two females were able to choose whether to be alone or together, they spent 90 percent of their time together. Two females will tend to get along best when they have been raised together.
Grouping rabbits increases their activity level as they chase each other and play with each other. If you get a male and female rabbit then they must be neutered and spayed.
