Yes, I did this.

Now before you start thinking I'm some kind of husband-abuser or into any kind of kinky stuff, hear me out. Snickers and I always play wrestle. We play wrestle way too much, even while waiting in line at the grocery store. We clearly watch too much UFC and whatnot so our play wrestling time tends to get quite physical. Kicks to the shins, pulling of the ears and hair, and knuckle punches to the top of the head are all moves we think funny to test out on each other.

I've never resorted to using my nails though. Snickers hates getting scratched with a passion but today, after he put me in a brutal choke hold that left me limited to what I could do, I pulled out the claws and scratched him in attempts to free myself. It worked... of course it worked. Mind ya, he wasn't too happy afterward and it left our bedding bloody.
