Wow, that's just horrible. Those boas might eat the ball python, I've heard about it happening, not sure how common it is, but it's not common to house boas with balls. I have a really nice petstore where I live, it's called Seattle Reptile and Fish, although they do house ball pythons together, they're usually all around the same size and they take good care of their other animals too. Especially the frogs, turtles, and lizards. They have really nice enclosures and get fed well.
