If my Mrs said Go Vegan I'd say you go elsewhere, fortunately based on the massive leg of Lamb she just brought things are good.
Does seem a little hipogritical to condone a pest kill but see yourself absolved because you didn't pull the trigger doesn't it, still each to their own and all the more for the Tinbum kitchen.
My mindset has always been if you must kill then use as much of the animal as you sfaely can, never just kill it for one thing and waste the rest, only exception being things like Rats out of diesease prevention however if I had an Animal that was safe to eat them I'd use it for pet food.
