Turn Around is Fair Play

Our cat Penny has a new way to torture our dog Missy. Missy is getting old and has a hard time maneuvering the stairs and takes a few moments to get started so usually I go upstairs first and know that she will be along in a few seconds.. but lately she's been standing at the bottom of the stairs and whining and when we go and look, here's Penny laying fully across the third or fourth step so that Missy can't get past her.. she gets really pissed off when we tell her to move too.. I have to say here that Missy has been chasing Penny since we got her almost so I guess this is Penny's way of getting to the top of the pecking order (literally).
