anastasia: Ive read books on it hun and vets are stumped as to the true reason they do it! One says they are taken away too early from their moms. I dont buy that.. Other vets say its just a comfort thing.. When they are truly comfortable and happy its like their happy dance on your belly!
I believe they do it when they are content and happy. One of mine drools when she does it on me. EWWW lol When they do it they purr and when they purr they are content. They do have scent glands in thier paws but not as many as in their faces. When they rub their faces (whisker area) on you THEY really are scent marking you then!
