Female sugar gliders become sexually mature at 6-10 months out of pouch(OOP). Male sugar gliders become sexually mature at 4-8 months OOP. A male sugar glider that is older than the female should not be introduced to the female until she is at least 6 months OOP to ensure that he does not rape her.
When a female glider becomes sexually mature, she will go into heat every 26 days for approximately 24 hours. If she is housed with a sexually mature male, then they will breed at the time. 16 days after mating the joeys should drop into the mothers pouch. Sugar gliders usually produce 1 to 2 joeys at a time, 3 is rare and 4 is really rare. The joey/s will be tiny, about the size of a grain of rice. The joey/s will travel from the cloaca to the mothers pouch. The mother will lick a path for the joey/s to follow. Once the joey/s has made it safely into the mothers pouch it will attach itself to a teat will it will remain for approximately 65 more days.
Over the next 65 days you will watch the mothers tummy grow. She will open the pouch and groom the joey/s. Increasing the mothers protein will help ensure that she is able to produce enough milk for the joey/s.
About a week to two weeks before the joey/s are due to come out of pouch you will begin to see body parts sticking out. Eventually the mother will no longer be able to hold the joey/s in pouch(IP) and the entire joey will be visible. T his is not the joeys OOP date however. A joey is not considered OOP until it has detached itself from the teat.
Joeys are born with their eyes closed. Most joeys will open their eyes at about 10-14 days OOP.
Once the joey/s is detached you can begin to handle it. Start off at just a few minutes at a time gradually increasing the time everyday. The first few days the mother may tuck the joey/s back into her pouch while she gets out to eat and play. About a week OOP she will no longer be able to stuff the joey/s back into her pouch and will leave them in the sleeping pouch while she is out eating and playing. Most of time the daddy will baby-sit the joey/s while the mother is out, other times they will leave it alone and tend to it when it cries.
When the joey/s reaches about 5 weeks OOP, it will begin to venture outside of the pouch, into the cage. At this time the joey/s should begin to sample solid foods. By the time the joey/s is 8 weeks OOP it should be fully eating on its own every night.
