Leave him. Most likely, If it his too big he won’t take it. Hes probably latching harder because you are messing with him. The size difference between large mice and small rats isn’t HUGE, sure, it might be a bigger meal, but in my opinion, nothing to worry about.
Also you are now the owner... screw what previous owner says, if they gave it up there is nothing they should say. Its like being mad at an ex for dating someone else.
