What does warfarin do to rodents?

Warfarin stops VKORC1 from doing its job, thereby suppressing vitamin K. The clotting process fails, and bleeds continue to bleed. Rodents can evolve to shrug off warfarin by tweaking their vkorc1 gene, which encodes the protein of the same name.

What happens when a mouse eats warfarin?

Warfarin is an anticoagulant widely used in solid or liquid commercial mouse poison products. It is tasteless and odorless and is designed to be combined with a bait. As mice consume the poisoned bait over the course of several days, their internal toxicity increases until they die.
