"You're touching me"...

I came to a realization tonight. The interactions between my cat and dog remind me of a commercial where a brother and sister are sitting next to each other on beach towels. The brother repeatedly pokes her in the arm to which she says in a monotone "You're touching me...you're touching me...you're touching me" while the brother grins with the obvious joy of tormenting his sister. I saw the similarity because when I watch Sadie and Maia, Sadie will run up to the window ledge, balance on her back paws and try to nip at Maia. Maia, at each attempt, meows menacingly and takes a swipe at Sadie. It's become a ritual and I have to smother laughter every time I see it. The only time I interfere is when barks, hisses and claws enter the fray.
