Just crush some castor beans up and mix them in some nice chocolate to make chocolate castor bean balls, and feed them to each dog. About 3 would be more than enough for each dog. (Risin is VERY poisonous and undetectable. They WILL be dead, it will take no longer than 3 days. However, it IS a very painful death, but who gives a fuck. Just do it. They killed your cat.) 
Bon appetit.
