That's nice, but could ya move your hand a little farther back?
That's it; gettin' closer.

I'm like 99.9999% sure that 99.9999% of all domestic cats do this. All I'm sayin' is that if you're offended by the posture, keep you hands off the booty. :)
By the way, the dogs are just as elated to get their booty scratches on; it's just not nearly as photogenic. :)
rump hump day!
