Yeah, try and get a video, Jiggy-Ninja. That sounds hilarious.
I've never seen a cat just go nuts and bite someone after rubbing, purring, and all that nice junk.
Cats do have an attitude, though. My cat tries to bite me all the time, but she usually misses. I'm used to the bites.
I used to have a cat named Oreo. We had him at the same time as this dog named Cocoa.
So, Cocoa would be in our fence, barking away at Oreo, who was sitting safely outside of the fence.
And every now and then, Oreo would stroll in and walk towards Cocoa... then land a cat-punch on Cocoa's nose. The he'd leave.
Oh, yes... these kitties have attitude, alright.
