Augh. That's fucking ridiculous. You'd rather pay to have two cats put down than put a little bit of goddamn effort into finding a home for them? I... can't follow that line of thinking. There are so many avenues to find good homes for pets -- my vet's clinic has a bulletin board specifically for that purpose (lost and found pets, as well as people who know they can't keep their pet, but don't want to drop them at a shelter).
