We're hunting the wiley, waskelly wabbit.
Because it's literally true that these rabbits are actually feral, it just doesn't sound right- does it?
Like a feral cat, or a feral dog, or even feral pigs that need killing- a feral bunny just doesn't seem to fit.
Unless you're in a town over-run with the things and things are so bad that the town council votes to allow rabbit hunting inside the city limits.
What gauge for killer rabbit?
