Getting a kitten!!...(pics added)

[Shelteez2]

My boyfriend and I are thinking of getting a new kitten.

I have a few questions though. Is there any certain rules that say cats of the opposite sex get along better than same sex?? They say this about dogs, and I know that's mostly a myth. I'm not sure about cats though.

Also tips on introducing the new kitty to our family of two dogs and one cat would be appreciated.

Thanks!
