I've heard arguments that rats are more nutritious, but until someone does a detailed analysis it would be hard to say for sure.

Your snake is 2' long approximately, but that could vary depending on girth, weight, etc.

The normal rule is to feed 1 appropriate sized prey item (determined by being no larger than the maximum girth of your snake)


My one BP that I had been feeding a normal mouse to, i now feed a 40 gram rat to (one who has opened its eyes, but may or may not be eating solid food)

Just depends, its best to eyeball it and go with the girth thing
