If she drinks and pee he should be fine... My male dont eat from end of January he was 1217 now he is 1103 but He shed recently and is moe active so I will try offer food today.. I for purpose dont offer food last 3 weeks and will try live weaned rat now (40-45g) range... this size of rodent should be safe to leave over for couple hours (will supervision of course) if he don take it... wait 2 weeks and try again... So Far In my opinon there is no reason to be worried ... at least Yet.
