What size prey should a BP that weighs 177g be eating?

My snake weighs 177 grams. He has been eating two hoppers once a week (and I usually alternate one week two and the next one) but I just went up a size to mice weighing 19 grams. Do you guys go by the 10% of body weight rule or 15%? 10% would mean the mouse is somewhere around 17 grams and 15% is somewhere around 26 I think? These numbers aren't anywhere close to one another so opinions would be appreciated!

I don't generally go by any body weight rule, If the prey item is smaller around then the widest part of the snakes body it should be able to handle it.

10-15% is just fine. It sounds like a huge difference but the fact is it's only 5%. You are feeding twice a week? Every 5 days is sufficient

No no not twice a week. Once a week but I feed two hoppers at a time every other week. On the off weeks she was only getting one hopper. A user on this site told me to double feed at a meal if the prey size is too small and the next one up is too big.

My bad, I was thinking you meant twice a week as in every like 3 days

Twice a week is fine for babies

The reason I'm asking is because she skipped her first meal last night which is abnormal for her and I was wondering if maybe it was too big, but it seemed appropriate and she are the first adult mouse I gave her a week ago. I'm thinking she is going to shed soon ( hopefully) and then will be back to her normal self.

I would feed a rat pup no wider than the widest part of the snakes body every 3-4 days. Once your snake reaches about 300 grams you can slow it down to about every 5 days. Once mine hit about 700-800 grams they get fed every 7 days.

Does anyone know if they have rat pups at petco? I dont think I saw any.

I would say once a week, and feed about 10%, that's about 20 gram an almost adult mouse or small rat, remember it's always best, to use rats :)
