Don't personify them. They do not "want war." They are wild animals looking for a meal. Hopefully your changes have made him less accessible. It IS possible for a rabbit to die of fright, so it is just as important that Floppsy feels secure and safe.

Of course they would be around more in winter - there is less of a fodd supply around then.

Why would money - "buying him from your Dad" - make any difference in whther he is indoors or outdoors?
