You stole the thoughts from my head. I am interested in the actual numbers. I have found that with my 2 snakes (ball python and diamond x jungle carpet) about 50% of what the snakes eats gets retained as body weight while they are growing. My carpet python who is new to me weighed in at 105 grams when I got her and was 201 before her last feeding. She had eaten 181 grams total in that time. That's retaining 53% of each feeding as body weight. Personally with all I have read I would not feed more than every 4 days and no more than 20% of their body weight while they are young and growing fast. I personally shoot for every 5 days and try to feed between 10% and 20%. Nothing in this study really surprised me but I am holding out to see how the total weekly prey weight compared between the snakes fed multiple smaller meals and the the ones fed normal meals.
