For a female's first pregnancy is it common only to have 1 joey? I don't know if she lost one or only had one to begin with? I have a neuter apptointment for my male on the 25. I don't want to neuter him if she loses both joeys.

According to the Merck Veterinary Manual, gliders have 2 joeys 81% of the time. While that may seem like a lot, there's still plenty of room for a 1 joey litter.
