No... There are many way to rabbit hunting. More than I know probably. Some ethical, some not. Depends on how you look at it. Here are a few:
[ul][*]Use of Dogs[*]Jump shooting[*]Stalking[*]Use of Ferrets[/ul]
I find that hunting them with dogs are much more rewarding. The time put in to training your dog and watching it work is brilliant. Jump shooting and stalking them is no fun for me. In Michigan, I think the use of ferrets is illegal.

If your hunting for meat, get them anyway you can. I just hunt them for enjoyment (mind you I don't spare any rabbit jerky ) so I love hunting with my beagle.
