Does Your Snake Ever "Adopt" It's Food?

So, he has a rat and a ball python, living in the same cage? He feeds the rat in there and cleans up after both of them? For over a year? And he then puts another rat in, the snake goes into feeding mode, only on the new rat, and never bothers the other one? And this has gone on constantly for a year? I have never even heard of such a thing. I'd love to see a video of this if he has one. I've seen rats not get eaten, and snakes coil up around them to sleep cuz their warm, but nothing close to that. I almost want to call shenanigans, but life is a strange thing.
