Cat vs. Ball Python = Cat Won

[Evilme5229]

Hey guys,
So my friend had his bp escape. Well, his cat found it. Its still alive, but its def. got some damage. I don't think that its going to survive because although there are no chunks or pieces missing from him, his bp has some areas were his skin is no long there, and few puncture wounds.
I know that my distributor told me a story about his bp that a rat got left in the cage and literally ate the back of the snake. Showing the snake's spine and the snake survived. I actually saw the snake when I visited his shop and its scarred all down its back and is pretty narley. I am sending him over there this morning to my distributor in regards to what to do.
However, I am just wondering if anyone knows any other stories or anything to be done here. I know that my experience with cats catching things, if the thing does survive that it adventually dies because the "venom" that the cat has in its mouth adventually kills the animal. I have seen this mostly with birds.
I do not know how the snake got out, so please do not start a big debate on it. I'm just asking for advice on how to treat and other similar stories. Thank you.
