LOL When I pet Daisy's back, sometimes I'll run my hand along the length of her tail, then hold the final 2 inches. She wiggles the tail until it's free and slams it with a thud. Then I do it again maybe 2-3 more times.

Penny does the same thing with hers, but I can't hold any part of
her tail. Oh no siree. Miss Cattitude won't like it I'm sure --I can pet it, but it needs to be in a non-stop motion. It's so funny when they slam their tail-- but they lift it back up again straight up as if asking me to "do it again"

Well, they like the back massage mostly I guess but I think they like the tail thing too. They never tried to bite/protest/scrtch/swipe .. I've been doing it to them since they were little--maybe that's why.
