Not exactly sure how much the large mouse weighed. And i thought a small rat was to big, but she got it down with minimal effort.
At that size a small rat is a pretty big meal (assuming we're talking 60-80 grams or so).

I feed on the conservative side, so I can't speak from direct experience, but from I understand larger meals can often lead to food strikes and inconsistent eating.
It may be worth grabbing some weaned rats before offering the smalls.
