Okay, I got some pics of my latest litter of ratlets...they're about 9-10 days old in these pictures.

Here are my subjects: -One is female, one is male...superficially, you can't really tell which is which...

Here are some close up shots of their...erm...genitalia..."money shots", if you will...I've placed arrows pointing to the anus and genital "nub" on both, so you can compare...

This is the male:

And this is the female:

As you can see, the distance between the nub and the anus is smaller on the female...also, the males tend to look more "swollen" in that area, I assume it's because of the developing scrotum.
