Notes:

At the risk of being called a furry, this is my Khajiit from Skyrim. With a few mods and an artist's eye you too can make a cute looking catgirl in Skyrim. Here's which mods I recommend using:

Pretty Khajiit
CoverKhajiits
More Khajiit Hair Styles
KS Hairdos Beast Races
83Willows Whiter Teeth
Feminine Khajiit Textures
CBBE Body mesh
Feminine Hands
FemFeet Redesigned
The Eyes of Beauty
Racemenu

Racemenu in particular has some great additional features if you are a bit more daring, since you can actually make manual tweaks to the facial mesh like I did. If that sounds too intimidating though, do not worry because it's more for giving your character a bit of extra personality and is not by any means a required step.

Enjoy!
