I say anything under 500 grams that is on mice should be every 3-4 days. If you go by girth of snake to girth of mouse you could be under or over feeding. Some are slender and some are plump.

Like this for example. You go to get a feeder and they look smaller then your snake girth wise. 1 is under feeding 2 may be over feeding depending on the weight of rodent to the weight of your snake. That is if you go off the 10-15% rule.

I say feed every 3-4 depending on the size of the prey. Just do what you think is right. When you ask a question like this on here you will get different answers for sure. It ultimately ends up being your call on what to do. I like many others see nothing wrong with the 3-4 day schedule for the youngins.

When they are small they are constantly growing like a weed. They absorb majority of the prey instead of deficating it out. They can use the extra food when young. J ust dont feed them 3-4 days the rest of their life. Once they get into fatty rats, normally over 500 grams/ 1 year old feed every 5to7 days.

I just thought about this, a problem with the whole 10-15% rule. So when your snake is over 2k or 3k grams do you still go by the rule? No way. People feed full grown adults a medium (80) gram rat once every 7 days, some even go longer.

I am sorry to stretch this out but the whole 10-15% rule is something I have a problem with. There is loop holes everywhere, try to go off the girth of your snake. Only you can tell if they are still hungry and I bet with the size of your snakes 3-4 would not be a problem if done correctly..
