Warfarin can be toxic to dogs and cats. The vet can treat animals for
accidental warfarin poisoning, but it is better to avoid using mouse
baits around cats. Warfarin also is used to treat some heart problems
in animals as well as people. Small doses are therapeutic. Overdoses
are not.

Another problem with mouse baits is that the mouse crawls into a
hidden place to die and decompose, filling the house with the odor of
rotting mouse corpse.
