Vicki Jo Harrison, The International Cat Association (TICA) president, via 'Newsweek'.<br />Rubbing behavior is usually a sign of marking territory, acceptance, or greetings and adoration.<br />The TICA president suggests that a cat rubbing its head or body against you is just a form of greeting <br />and a way for them to say they are happy to see you.<br />"You may notice this more when you've been gone for a longer time and return home." Vicki Jo Harrison, The International Cat Association (TICA) president, via 'Newsweek'<br />According to 'Newsweek,' cats are possessive animals that like to claim humans as part of their territory.<br />Cats use glands in their cheeks and chin to release friendly pheromones that usually mean they are marking you as a friend.<br />"Rubbing and head butting is their way to mark you again with their scent. This allows your cat to reclaim their territory, and increase their endorphins, which gives them a sense of calm, happiness and safety" Vicki Jo Harrison, The International Cat Association (TICA) president, via 'Newsweek'.<br />Cats can also use headbutting and rubbing as a way to indicate something they need.<br />"For example, if your cat rubs against the cabinet that contains their food, they are likely trying to alert you that they are hungry or need freshwater or as a reminder to clean out their litter box."
