I understand and have given the advice to feed one prey item slightly smaller than your snakes girth once a week. However, last night I was thinking... If I have 2 snakes that are from the same clutch, and both are 2.5 feet long. Let's say that they are both 1300 grams. Then one goes on a fast for a few months and the other one continues to gain weight.

Now one is 3 feet and 1500 grams and the other one is 3 feet and 1100 grams. The girth of the 1500 gram snake is larger than the 1100 gram snake, but don't they both have the same dietary needs? In this case I would think that feeding 2 smaller prey items that add up to the same amount as one larger one to the girthier snake would be acceptable, is this right or am I off?

I've also started measuring prey by weight as well as girth, so that I can compare sizes vs weights.... so far on snakes 250-900 grams I have been feeding prey by girth, that weighs 1/7th to 1/5th the amount of the snake.

IE I feed an 800 gram that is skinnier a 114 gram meal, thats 1/7th the weight of the snake. I feed a girthier snake that also weighs 800 grams a 160 gram meal and that is 1/5th the weight of the snake.

Anyone else done weight comparison in addition to girth?
