Can dogs or cats get secondary poisoning from eating Dcon poisoned rats?

I don't know about dogs but a cat that is exposed to even a small amout of rat poison can later develop kidney disease or kidney failure, both of which are fatal. It happened to one of my cats and it was heartbreaking. I did keep her going and comfortable longer by giving her sub-q fluids every day. It isn't hard to learn how to do and it keeps them hydrated. Bring them to a vet asap!
