Speaking of catfights, you probably wouldn't want to get into one with Sonja or any of the taloned tempstresses at Fetish Nails, unless you wanted to wind up with a gouged eyeball and plenty of bloody scratches all over your body. (Then again, gouged eyeballs and bloody scratches are probably exactly what you'd be looking for when you visit these sites, so forget we said anything.)
