Dougy the kitten used to put his front paw on my arm when he slept by me on the computer desk. Now that he is a mature cat, he steps it up and wraps both front and hind legs around my arm. So much for using the mouse or much else! (So I did manage to take the photo with my smart phone, using my left hand and left thumb. Even I was amazed!)
Oh well, come winter, I’ll appreciate the arm warmer!
