The difference between a Female and Male cat? (10 points)

[smithers]

I found a stray cat on the street and i took it in (it has no owner and its perfectly safe). And i am just wondering, how do i know if it is a boy or girl? Are there any physical features that I could check out or something like that...?

Thanks in Advance, and please be specific because i dont know much about cats.

Honestly, sir... If you don't know the difference between a male and a female... Wow.

You look, and see if the cat has a weener. If it doesn't, it's a girl.

does it have balls?
