Cats communicate with each other through body language, vocalizations, and scent marking. Common cat behaviors include purring, meowing, chirping, hissing, growling, and rubbing against people or objects. Cats also use their tails to express their feelings, with a raised tail indicating happiness and a lowered tail indicating fear. Cats may also use scent marking to communicate with other cats, by rubbing their cheeks against objects or spraying urine.
