Why Do Cats Meow at Each Other: It’s Mostly for Us

Cats rarely meow at each other. The meow is one of the most common sounds cats direct at humans, but in cat-to-cat interactions, it’s actually rare. When you hear two cats vocalizing at each other, they’re almost certainly using a different set of sounds: trills, yowls, hisses, growls, or screams. Each of these carries a specific meaning that other cats understand instinctively.

Why Meowing Is Mostly for Humans

Domestication fundamentally changed how cats use their voices. The meow appears to have evolved specifically as a tool for getting human attention. In feral cat colonies, where cats live independently of people, the meow is a rare vocalization. It shows up occasionally during territorial marking or mate attraction, but it’s not part of everyday cat-to-cat conversation.

Research comparing how cats vocalize with humans versus other cats found that cats intentionally raise the pitch of their vocalizations when communicating with people. Cats directed an average fundamental frequency of 615 Hz toward humans but only 447 Hz toward other cats. In other words, the classic high-pitched “meow” you hear at home is a sound your cat has tailored for you, not something it would use on another cat.

Kittens do meow at their mothers to signal hunger or distress, and the meow is more common in younger cats than adults. As cats mature and no longer need to call for a parent, they largely drop the meow from their social vocabulary, unless they live with humans. Pet cats essentially retain this kitten-like behavior into adulthood because it works: you hear the meow, and you respond.

What Cats Actually Say to Each Other

When cats interact with other cats, they rely on a richer and more nuanced set of vocalizations. Trills, those rolling, musical sounds that rise in pitch, function as friendly greetings. Cats trill at each other to express affection, signal a desire for interaction, or strengthen social bonds within a group. Mother cats trill to communicate with their kittens, and bonded adult cats use trills as a casual “hello.”

Chirps and chattering sounds serve different purposes. You might notice your cat making short, staccato chirps while watching birds through a window, but cats also chirp at each other during play or moments of excitement. These quick bursts of sound carry a lighter, more animated energy than the drawn-out meow.

The sounds cats make at each other also tend to be more varied in their pitch range. While cat-to-human meows hit a higher average pitch, cat-to-cat vocalizations cover a wider spread of frequencies, with more dramatic rises and falls. This suggests cats pack more information into the tonal shape of their sounds when talking to each other.

Sounds That Signal Conflict

The vocalizations you’re most likely to hear between cats are the loud, unmistakable sounds of disagreement. These aren’t meows. They’re warnings.

  • Hissing is defensive. A cat hisses when it feels threatened or cornered, warning an intruder to back off. It can also serve to establish dominance during a standoff.
  • Growling is more aggressive. Unlike a hiss, which says “leave me alone,” a growl is a preemptive warning that the cat may escalate to physical aggression if the threat doesn’t retreat.
  • Yowling is the long, loud wail you might hear from cats outside at night. It’s commonly tied to mating behavior in intact cats, but it can also express general distress or territorial claims.
  • Screaming typically happens during or immediately after a fight, or at the climax of mating. It’s short, sharp, and intense.

If you’ve heard two cats “meowing” at each other through a window or across a yard, what you likely heard was yowling or growling. These sounds can superficially resemble drawn-out meows to human ears, but they carry entirely different messages in cat communication.

How Cats Prefer to Communicate

Sound is actually a secondary communication channel for cats interacting with other cats. They rely far more heavily on body language and scent. Tail position, ear orientation, the speed of a slow blink, the arch of a back: these visual signals convey most of what cats need to say to each other in close quarters. Scent marking through facial rubbing, scratching, and urine handles long-distance communication, leaving messages that persist long after the cat has moved on.

This makes sense when you consider that cats are solitary hunters by ancestry. Unlike dogs, which evolved in social packs where vocal coordination was useful, cats had little evolutionary pressure to develop complex vocal exchanges with their own species. Their wild ancestor, the African wildcat, is a quiet, solitary animal. The domestic cat’s vocal repertoire expanded primarily in one direction: toward the humans who control the food, the doors, and the attention.

Why Your Cats Might Vocalize at Home

If you have multiple cats and hear them making sounds at each other, context tells you what’s happening. Friendly trills during a greeting or before a mutual grooming session are normal social bonding. Hissing or growling during a tense encounter near a food bowl or a favorite sleeping spot signals a territorial dispute. Sustained yowling between two cats who can see but not reach each other often means frustration or a redirected territorial response.

Cats can also hear frequencies far beyond what humans detect, with a range extending from 48 Hz up to 85,000 Hz, one of the broadest hearing ranges among mammals. Some of their subtle communication may include vocal components we simply can’t perceive. The quiet chirps and low-frequency sounds that pass between familiar cats likely carry more information than we realize.

The short answer to the original question is that cats mostly don’t meow at each other, and the fact that they meow at you so readily is itself the interesting part. Your cat learned, probably as a kitten, that making that specific sound gets a reaction from the large, useful creature it lives with. With other cats, it has better tools.
