This man (woman?) found this little bunny (hare?) alone and “grown it”….

This is a very tender, loving short video and/or it is amusing and/or something is wrong, depending on your point of view. It is certainly great to see somebody rescue a newborn rabbit (that is what the title says) and raise the animal to adulthood. Great job. On the other hand, some say that this is a hare and hares can raise themselves independently as soon as they are born! And some would say that this is not a man because if you watch the video through you will see polished nails and rather feminine hands halfway through! Perhaps she’s his girlfriend but as she’s involved then the title is wrong 🙂 .
There are other issues. The video asks some questions. What is the background? How did this tiny, baby bunny arrive at that spot and what was the person doing filming it? And how do you raise a bunny from new-born? That’s a big one. The aptly named website rabbit.org tells us that less than 10% of orphaned rabbits survive a week. And they state that “wild babies are most often not orphaned“.
They also harshly state that people who try to keep them alive might be committing an illegal act and it is unnecessary and potentially harmful! They advise that you should put the bunny right back where you found him, in the general area, because their mother will come back at night and find him! Then you should leave the area. Well, that makes the video look a little less good 🙂 .
Then call a wildlife rehab or rabbit vet immediately. They say that rabbits sometimes make their nests in the middle of the lawn in plain view of everybody else. That probably explains why this rabbit in the video is where he or she was. If a nest has been disturbed do what you can to restore and protect it.
