As babies, they love to eat. My little girl ate every 3 days from 90g up to 500g. Then I switched her to weekly up to 1000g. Now she gets a small to medium rat every 2 weeks. 10% applies to babies up to around 500g. Once they are that big, you just feed them prey as thick as their thickest part. And then once they are 1000g+, a small to medium rat will be plenty for them every 1-2 weeks.
