Cats communicate with humans and each other through a variety of methods, including vocalizations, body language, and scent marking. Vocalizations such as meowing, purring, hissing, and growling convey different emotions and intentions. Body language, including tail position, ear orientation, and posture, further communicates a cat’s feelings and reactions. Scent marking through rubbing or scratching allows cats to establish territory and familiarity. Additionally, cats use subtle cues like slow blinking to show trust and affection towards humans, illustrating a complex system of interaction and communication.
