There are gazillion more parasites in a dogs/cats salvia, they do lick/clean their own arses.....and every other dog they meet(and then there's this special interest in each others feces!!!!), than in some washed vegetable. I've had two cats and seeing some of the "alive and kicking" stuff coming out of them was like taken from a freak movie. Lots of the parasite websites are directed to curing pets. I know it sucks to hear that a beloved one is a major source so I totally get the in denial bit....
