That's a lousy situation.
The problem with throwing them over the
fence is that it teaches
local predators where to find easy food. They will not ever forget that lesson. Ever.
Unless they are freshly killed and rapidly processed, I think they may be a bit dodgy for people food. But there are all sorts of people who will pay a little for fresh, raw dog/cat food.
Other than that, dig a hole and plant a tree.
Side note: people used to pay for weasel skins. I wonder if that is still true.
