There is a situation quite similiar on the Long Beach City College campus. Someone at one point dropped off their unwanted bunny(ies) and there has since been a running population of buns on the campus. I emailed someone there once to know more about it, and no one there really had many details about when it started, or where it started FROM. But, they did find an article that focused mainly on the fact that there is the problem of how to handle various health problems the bunnies tend to have, not to mention their terrible diet from all the human food they're fed on the campus.
Hopefully one day someone will be able to handle these types of situations. It's a shame that it's allowed to continue, and that everyone's become so apathetic about it. I wish there were something I could do, but ultimately, I live in a one bedroom apartment, and already have four animals, so I'm at my limit!
All my love to all those bunnies!! :heartbeat
