depends on the snake how many eggs(Pythons) or babies (boas) they have . can be anywhere from 6-30 at a time. I lived in Florida from 03 to 08 and the only time i ever heard of a non native snake eating a pet was last yer in Ocala. This was the case of a ball python strangling a parrot in a outside aviary. There was also the case of the of the burm( i think) that was trying to et the gator, or the other way around. Anyways killed them both. To be honest i am more concerened about humans pushing dangerous native wildlife out of their habitat by building in their breeding and living grounds. We have to stop building those sub divsions all over the plac,espec in Floirida. Even the gators have a right to existence. If we would stay away from habitats we wouldnt have to worry about pets geting eaten. Other than that i rather have wild animals than folks that let their dangerous dogs run loose.
