I think you probably fed her a Zuker rat that has much larger amount of fat. Boas especially have a hard time digesting it, and as a result can get sick with runny feces or much worse. They're the type that rodentpro.com sells as their 2 largest rat sizes (and they'll even say in the product list that they are a different strain if you look).
It's much better to stick with multiple smaller normal rats than to feed one of these morbidly obese Zuker rats.

Most pythons don't have a problem with them, although they certaintly aren't as healthy as a regular rat, but I've heard that some do so the poster may have fed their python a zuker and the python is reacting badly to it. Certaintly sounds typical of such a problem.
