I got girls cause they're smaller and sans goolies. Plus they dont' have the buck grease smell, and are more willing to come visit me while I read and then leave and entertain themselves.
But one of mine, Sevilla, I'm sure thinks she's a boy- she'll sit and let me scratch behind her ears as long as I can, and she looooves when I rub up and down her back (stands her short hair on end, it's so cute).
The other one, Belgie, is more "typical" girl, hyper and jumpy and explorative. She likes taking food from me, running away to hide it, and coming back to demand more, walking all over me if she thinks that'll get the job done.
So you can try all you want for what you think a normal example of the gender will be, but just keep an eye out for surpise personalities!
