Thanks for the reply! And I fed her a hopper once, she ate him really fast. And after that I didn't notice any bulge.
With the adult mice it takes her longer to eat and TBH I never noticed a bulge. But most of the time she's either burrowing or under her hide especially after a meal. But fr what I did see of her there wasn't a bulge. But next time I feed her I'll be sure to get a good look at her and maybe take a pic just to be sure.
