A friend of mine works for a pest control specialist and recommended using contrac with a bittering agent so if my cat does get a mouse that has eaten poison, it would be highly unlikely to try to eat it.
Contrac Rodent Place Packs do not contain a bittering agent. Gladiator All Weather Blox contain a bittering agent. Gladiator is just as effective as Contrac and will kill with in 1-2 days after consumption.
