It's sunny for most of the day, and is also a good vantage point from which to keep track of the dog. Stumpy stretches out a sneaky paw and swipes the dog's nose when he gets too close. In the late afternoons of summer there may be other cats up here as well, enjoying the quiet time before the evening meal, in an uneasy truce. Of all our cats Stumpy can be the meanest to the dog, who is a very poor judge of cat character and often has the scratches to prove this. She will pretend to ignore him until he comes in for a close sniff, then she'll attack and howl her menacing battle cry.
Victim dog slinks away, defeated again.
Poor Tajdog - he never learns.
