Cats communicate with humans through a combination of vocalizations, body language, and actions. They may meow, purr, hiss, or growl to express their feelings or needs. Cats also use their body language, such as rubbing against you, tail flicking, or kneading, to show affection or communicate their mood. Additionally, cats may bring you gifts, like a toy or a dead animal, as a form of communication or as a way to show trust and care.
