I got some problems sexing my young felinus. I would be very happy if someone could help me with that.

greets,

Tim

how old are they?

[Tim]

They are 6 months old.

[tanala]

maybe a little too young to sex. I have not much experience, but had a male that showed distinct hemipenis bulges at 6 months of age. If you dont see any signs of bulges, just wait some more time. I think they will be easier to sex at an age of 8 to 10 months

[Tim]

Thank you for the help. I know that the males develop a bulge and that the females are bigger than males. Males have also spurs on the side of the bulge. But is there any way to sex them at this age?

I've not had much luck in sexing them any younger than 6 months or so. Marcus has the most experience around here with breeding felinus. So, perhaps he will chime in with some advice.

Tim,Sebastian and Ethan are right in their estimation of sex becoming evident in juvenile Felinus.If you had several to compare,growth rate can also be used.Both sexes have histological spurs,so do not use that as an indicator.At 6 mos,you should see signs of protusion ,or bulging starting to become evident.By 8 mos it should be clear,95% of the time.I have had several show male right around 10 mos,not sure why later than others.I have began to experiment with keeping juveniles in small groups,and looking into population density and how it affects sex and growth rate.I have seen some animals start to lag behind others,only to perk right back up when kept alone from that point.Those same animals turned out to be male eventually.Hmm....

[Tim]

Marcus, thank you very much for your answer!!

Hi Marcus,

well I think I told him the thing with the spurs because I recognized my male does have spurs while my females only have a light spot on the equal place but no spurs.

Yes,at an early age they appear the same,then as they age,the spur in the male takes full shape,that's why I mentioned it because of the age of his gecko.Once,the spurs start showing defined shape,so should you start to see a bulge.I should have elaborated by saying do not use the spurs "solely",especially with very young animals.You are still right Siri,because they are an indicator,when they start to show that difference.
