OK so for a veteran suggie lover I should be embarassed about this...
GummyBoo is a boy. Yes, when we rescued (him) her former owner told us GummyBoo was a 2-yr-old female. And what with the absence of a PomPom, we figured she was. And since we are slow to do a lot of prodding with a new rescue, we took what was told as gospel.
But earlier this week I was rubbing GummyBoo's tummy and the "pouch slit" on her looked a little low and more like a neuter scar. Upon further inspection, and after gently pulling apart the fur in the "pouch area" and upon finding no pouch, we laughingly have re-sexed her as a him.
Regardless of sex, this little creature is doing fine. He's not much of a jumper and still does not respond to normal "play" activities such as chasing and teasing, but he is friendly and curious.
Stay tuned. I don't think his sex will change again :-)
