You definitely need to either convince your Dad to let Floppsey live inside, or raccoon-proof your cage. The raccoons will NOT forget after being "scared off" a couple times, they are creatures of habit, and are pretty smart, too.

Floppsey is right to be scared. He is a prey animal, and is pretty defenseless.

Go to http://www.rabbit.org for information on bring Floppsey inside safely, and maybe the inofrmation can help convince your Dad. There is a lot to do to "rabbit proof" a room, but you might be able to keep him in just one room of the house ...

Good luck.
