How many pounds of food does a ball python eat ad?

The amount of food depends on the age of the ball python. Generally their meals are actually measured in grams, as they only weigh a couple of pounds themselves (or not even a pound for babies). As babies, up until they're 500 grams, they get 10-15% of their weight weekly, and as adults all but the biggest should get one small rat every 1-2 weeks.
