I also am having a hard time with the hand drawn pics. My kittens are only about a week old. Can anyone tell me how to tell? Maybe I should post some pics?
The best written description I have found was this:
With the kitten upright (as though standing on it's feet) the genitals of a female will look somewhat like an upside down exclaimation point, while male genitals will look more like a semi-colon.
The urethra and anus are also closer together on females.
