Most people think rabbits are “natural” when they may actually be invasive. So they let them go. Finding a new home is the last thing on every one of these owners mind.

You cannot release them into the wild, just like you can’t release penguins from the zoo into the wild. We spend most of our adult life teaching our children how to survive. Most people don’t teach their pets how to survive.

No offense, but your question makes no sense in the scope we are dealing with. But fwiw, most people released from prison don’t do so well with reintegration. Some don’t survive, some end up going back, and very few thrive.
