I feel for you. Also as stated, just keep an eye on their weights.
I have a female that is around 400g and she is the one that worries me the most.
She will only eat mice, and only every three to four weeks.
The good part is I can get her to eat two at a time.................................the BAD part is that she will only eat live, I have to put two mice in her tub at the same time AND (this is the part that always worries me) her tub has to go back in the rack with total darkness.
I feed all my snakes live but I dont like not being able to monitor her, if she has any type of disturbance during the time she decides to feed she will stop feeding and then its another weeks wait to try again.
