I think calling social services was the best thing to do for the children involved, but I doubt the snakes will fair well (unless they are of educational value, or a rare species, etc.) they will probably be confiscated and put down (you didn't mention wether or not the owners had the required permits, etc. for the hots; and what species they kept). I think people such as the ones you describe would be better off sticking to cats and dogs (IF they are even fit to care for mammals). The children are safer now, but this experience may leave them with a bad taste in their mouths regarding reptiles in the future. Every responsible reptile owner strives to educate and endear reptiles to other people, and it seems like these owners didn't give much thought to their children, their pets, and other people, let alone themselves. I would have done the same thing. Give us an update soon!
