35g is very light for a breeding female. 45g is safer but the traditional '50 g' is probably the earliest point one should consider breeding female leopards.
Not only should one consider the stress from the male but the stress of carrying and depositing eggs, several times through the breeding season. Even when offered the maximum number of feeders, my females always loose weight during the breeding season and take some time to bulk back up afterwards.
I introduce the males in with the females during the day, leaving him in with her during the night and then pull him out the next morning.
