My adult female cat Dusty does something I don't understand. While I'm standing on my back porch, she'll come up behind me and jump up, tag me with all fours and no claws above the waist then run and hide in the grass. She's the most polite cat I've seen with her claws. Anyway, just wondering if I should respond other than by playing a little "stalk and pounce" with her? No other cats on the property with the two of us, and though neighbor cats are around, I never see her playing with them.
