My cat Cleo is a stray I adopted about a year ago. Since day one she likes to climb up to my chest and wrap her front paws around my kneck and commence licking my neck. Then follows with a long nap. I feel bad because if I stop her she gets frustrated and gos off to a closet to sleep. Like I am denouncing her or something. If I let her she becomes very content. I have several cats and lots growing up. Never had I had a cat insist on this routine. I feel like maybe she thinks she is cleaning me and that is her way of showing affection? I feel bad if I don't let her just a little. But she scratches my kneck with her paws and I also worry if I can catch anything from her. I wash off afterwards. What is this??
