I work from home and when I sit at the computer, one of my cats, a calico, will jump up on my shoulders or the back of the chair and purr to say I want some loving and why do you spend so much time with that thing when I am here.
If I don't take the hint, she jumps and walks between the computer screen and my face hitting me with her tail.

She also has started using my husbands legs as a scratching post. She is declawed so it is no big deal, but it clearly is her way of reminding us who is the boss around here.
