Advice on Feeding

[John1982]

In regards to the medium rats, do you feed her only 1 or 2 then? Maybe I'll start with that and then go up to a large rat in the future.

Medium rats are 2-3 times larger than hamsters. I'd start smaller - somewhere between a pup and weaned. Don't worry, by the looks of her, she's got plenty of reserves. Usually when people switch up prey items on an imprinted animal, they try with similar sized or smaller options. Going the opposite way could just intimidate your snake out of any feeding interest.
