Luna, my fat ass black cat has found she likes to be spanked... She eagerly and willingly will turn around with her butt facing me and mews. When I start smacking or drumming my hands on her rear (gently of course, it sounds worse than it is) she goes nuts and tears at the surface (in most cases in her favorite spot on a rug on the edge of the conversation pit) she's laying on. If I stop she bites me insisting I continue. I find this strange, hilarious and disturbing. XD I hope to have a video of her soon. In the meantime, here's what she likes: http://www.youtube.com/watch?v=h6a8T5Z5wkk Trust me, it's not hurting her, she LOVES it (just like the cat in the video) and always comes running up and begging for more. WTF is wrong with my cats? O_o;
