Article in English: In the wild, it would be with other rabbits 24 hours a day, 7 days a week. If you only have one rabbit, you can give it some companionship, but it will still be lonely at night or when you are away at work.  Sometimes a female rabbit will be fine on its own. If you do not notice hyperactivity or withdraw with a female rabbit, it is possible that she might be content by herself.  On other occasions, a rabbit will be too territorial to get along with another rabbit. At that point, you should consider getting a different species of pet. These will provoke fewer territorial feelings, but can still be a source of company. When a bunny nudges you with its nose it is trying to tell you to do something. Often this means that it wants you to pet or play with it. It can escalate this behavior to even more direct and forceful modes of expression.  This nudging might progress to soft biting. This is also a way to get your attention. If you pretend to be hurt, the bunny should respond by nipping more softly and less frequently. Your bunny might even begin to dig with its front and or back legs directly on top of you, as if it were trying to dig you up. This is definitely a plea for attention. A lonely rabbit will sometimes become hyperactive and angry. Although it is not uncommon for rabbits to dig at things, this destructive behavior will accelerate rapidly. Watch for the rabbit gnawing at carpet and other furniture. Their behavior can even become self-destructive. A lonely rabbit can begin to pull at its fur and overeat. It might even damage its own teeth while pulling at the bars of its cage. Alternatively, some rabbits will become depressed. They will withdraw from you and others, refusing to interact even when you reach out to them. It will take some more effort to get these rabbits back in a good mood. A withdrawn rabbit might hide or stay in its cage. It might not respond when you try to pet or play with it.
