Our feeding schedule for the younger BP's is one appropriately sized prey item every 5 days until they hit about 200 grams. After that they go to one prey item every 7 days for the remainder of their lives. Depending on the prey item size compared to the snake, they may take two or even three in the case of big BP's and smaller african soft furred rats. You just have to get to know your snake and your prey items and you'll sort it out. For the longest time we were very rigid on the feeding schedules but now, with more time and experience, we're learning to "listen" more to each snake and adjust accordingly.
