I agree with Stephanie. You are likely to end up with two pregnant females, each giving birth to litters of an average of 5-6 babies. I adopted four "females" from the local animal shelter last July but they were actually 3 females and one male. All three females got pregnant (3 month gestation period). The first miscarried, but the second had 6 babies (5 survived) and the third had 7 babies. That's why I now have 16 degus. Please get him fixed ASAP or return the females or separate him from the females and only give him supervised time with them.
(I have spent, in less than a year, over $400 in dental bills, $400 in additional vet bills to ID the sex of the babies and investigate a possible genetic autoimmune disorder some of the babies may have, and $75/week in upkeep not to mention hours and hours of time and the hundreds of dollars in extra cages/accessories.)
