Would this be overfeeding?

that would be fine. one rodent every 3 to 4 days that leaves a slight lump in the belly is fine. as long as you have an 87 to 90 hot spot so the snake can digest the rodent properly.

Sorry to but in but I need to know something can I just feed mice there whole life or would I have to switch to rats what if they only eat mice what would be a good amount to feed thank you

not over feeding. hatchlings can go on 4/5 day schedule np.

My. Bp is 140 g also and I feed him every 7 days sometimes early because I can tell when he wants food when he's moving around his tank before feeding day sometime I feed him early if he is acting a different way but I feed every 7 days

We try to offer all hatchlings 2 times a week and we try to offer all sub adults every 5 days or so.
