how much and long will a dead rabbit smell?

[Cheesehead]

I have gone to war around my house with the rabbits. The last few years they destroyed my bushes and I am sick of the wife and the lady next door hounding me to do something. 2 years ago it was the Gophers and my neighbors watched in somewhat horror as i filled five 5-gallon buckets of water and did a fast pour down a few well used holes and proceded to stomp the guts out of 7 little gophers as they crawled out.
Well anyway, i took a shot at a bunny last night and hit it someplace in the front shoulder area and when it stopped flopping it laid in a place i couldnt shoot it again. I went up to it with a club but it ran under the Neighbors front porch and i assume will die there. Unfortunatly they like to sit out on the porch a lot. So how long do you think it will stink?
