New pic, shes a big girl...

Thought iy was a neat pic..

How big is your girl ? my Sav is 3 feet but I dont know how to find out how to sex it.

Shes a cross between a blackthroat and a cape banded whitethroat with the cape banded bred back to a cross female, resulting in her.

Compare (adults especially) head shape, nose shape, lower jaw shape and thickness, neck thickness, length from shoulders to hips, width of midsection, tail base, fully everted sex organs, females of course produce eggs.
Bosc monitors are not as easy to sex but to see them up close most times I can tell them apart. They can be "popped" by someone who knows what they are doing, but NEVER EVER get them probed, first of all it tells you nothing as hemiclitori and hemipenes can be the same length, and they are built different from snakes so even a very very good vet most probably will do permanent damage probing a monitor. Blood tests (both male and female monitors have high testosterone levels) and xrays tell you nothing unless you see eggs in a female.
Look at a few known males and females, then compare them.

really cute!
