Kittens are much more likely to meow than adults. Because kittens are born unable to hear and see, they make this noise to alert their mother that they need attention. Adult cats rarely meow at each other, but they may meow at us for the same reasons. (, but it’s usually for laughs.) Check out this kitten crying for its mother.
Does your cat make a variety of noises
Researchers have looked into these different cat sounds made by cats, trying to make sense of their language. I currently have a cat that has a sort of high-pitched trill mixed in with his loud roaring type of purr. Research reported a year or so ago in the journal "Current Biology" deciphered this type of meow as one that controls the human beings who live with cats. I can certainly attest to the fact that when my cat makes this type of noise, it's impossible to ignore him. In fact, the researchers named this type of purring with a cry embedded in it "solicitation purring".Cat-owners will recognise many of the cat-sounds listed, although we may refer to them in more anthropomorphic terms: greet, grumble, nag, whimper, swear, sing etc. Some cats add their own idiosyncratic words to this general vocabulary such as the sudden exhalation of air used by my own cat, Aphrodite. This word, which we call "foof" or "frooff" can be anything from an exclamation ("Oh!" and "Well"), a comment ("So?" and "Huh?"), a non-committal response when we speak to her ("Hmmm"), or a noise to be used when she feels she needs to say something, but can't think of anything meaningful to say (small-talk and self-satisfied murmuring). It all depends on HOW it is said. For Aphrodite, "froof" is the all-purpose "supercalifragilistic..." of cat vocabulary. Scrapper used "mrrrp" in the same way.The exact meanings of all of these sounds may be modified or emphasised by facial expression, tone/volume, body language and context (paralanguage). In his dealings with Scottish Wildcats, Mike Tomkies noted that the wildcats would greet him with a loud spitting "PAAAH" accompanied by a foot-stamp. I have received the same greeting from feral cats. The meaning ("*** off!") is unmistakable and only a fool (or a cat-worker intent on packing pussy off for neutering) ignores it. Some cats may use some of these cat-sounds in different ways when communicating with humans and only our familiarity with our own pets tells us that a certain type of growl is a play noise and not warning of imminent attack. Kittens learn a great deal from imitating their mother, and cats retain the ability to learn and adapt into their adult life. They soon discover that humans use sounds in order to communicate and most cats react to this by developing different sounds for certain circumstances. A plaintive miaow is best suited to achieving a goal such as extra grub or an open door while a friendly chirrup elicits a favourable response when the cat greets its owner. Many of these noises are accompanied by exaggerated actions as the cat "acts out" its communication - by running back and forth between owner and closed door or by licking invisible crumbs from an obviously empty food dish.
