Our girls, Shadow and Miss Hissy Slashy, are all over Hubby when he’s working (trying to anyway) on his computer upstairs. Shadow is especially stubborn. It’s his own fault because it’s easy for them to get at him. He has a nice, easy-to-jump-on desk that is completely bare on one side.
I have solved this problem by setting up a cat-obstacle course. They get partway through it on the way to my keyboard, and give up.
