At what point do you stop?

I follow the 10-15% rule when choosing prey size for Hera. Right now she is on 2 large mice (around 35-40g) every 5 days. She weighs around 250g so this is fine. My question is at what point do you stop upping the food size? Is it an age limit or a size limit?

I don't want her to be underfed but I don't want her getting morbidly obese either.

You'll have to feed A LOT to get a ball morbidly obese...especially with mice.
