Feeding xl rats to a boa barely over a year and claiming you don't overfeed is perfect lol, I just love how oblivious people can be. My 6', 5 year old male boa gets large prey a couple times per year, usually he eats mediums with 3-4 weeks in between meals. I just bumped my 2 year old dumerils boa about 4' up to small rats every three weeks. Save money on rodents and extend your snakes lifespan, feed conservatively.
