I have three cats and from the time that I had only one indoor cat this behavior has gone on. Whenever I go to the bathroom, one or more of the cats comes into the bathroom while I am sitting there and leg wraps and wants to be petted. I am not the only person who has cats that do this. Why do they do it, what does it mean? If I close the door, the cry at the door or stick their paws under the door trying to shake it open. I am considered 'The Cat Guru' amongst my friends and I would love to be able to explain this to them as well as understand it myself.
