Do cat translator apps work? What the science says

Do cat translator apps work? Not as translators. Researchers can sort meows from a few set situations, but that is far from translation. An app can still be fun.

What a meow is for

The cat welfare charity International Cat Care says meows are, in most circumstances, directed at people rather than other cats, and rarely heard between adult cats. People often reinforce the meow, which helps shape it into many forms, and some cats add personal sounds they only use with their owners.

At Cornell University, Nicholas Nicastro found in 2004 that domestic meows are shorter, higher-pitched and far more pleasant to listeners than African wild cat calls, consistent with meows being shaped by human perceptual biases. Earlier, in 2003, he and Michael Owren found people sorted meows from 12 cats in 5 situations only modestly better than chance. The two found little evidence that meows refer to specific things, calling them nonspecific sounds that attract human attention.

What body language adds

International Cat Care reads a vertical “tail up” as friendly intent and a tail tucked between the back legs as often meaning anxiety or fear. Dilated pupils with flattened ears often signal fear; relaxed, blinking eyes show a content cat. A phone's microphone catches none of this.

What researchers have classified from recordings

In a 2019 University of Milan study published in Animals, Stavros Ntalampiras and colleagues recorded 21 cats in three situations they set up: waiting for food, up to 5 minutes alone somewhere unfamiliar, and being brushed. From 448 meows, their best method identified the situation with a recognition rate of 95.94%. The authors call it a proof of concept. So meows from different situations differ measurably, but the system only picks one of three trained labels and produces no words.

People find it hard too. In a 2020 follow-up by the same group, less than half of 225 adults matched meows to the right situation. At Lund University, phonetician Susanne Schötz and Joost van de Weijer found that food-related meows tended to rise in melody and meows recorded while waiting for the vet tended to fall; listeners with cat experience classified them better.

Can your cat understand you?

A 2013 University of Tokyo study by Atsuko Saito and Kazutaka Shinozuka found that cats could tell their owner's voice from strangers' by sound alone. In a small 2022 study, Charlotte de Mouzon of Université Paris Nanterre and colleagues found that 16 cats told apart speech their owner aimed at them from speech to an adult, but not when strangers spoke: communication, the authors suggest, that relies on experience.

What an app can honestly do

Some apps are marketed as translators, but the research gives them nothing word-for-word to translate. What an app can do well:

• A playful read. A funny, human-style phrase is fine when it's presented as entertainment.
• A record. Saved meows let you compare how your cat sounds before meals or at a closed door; note the tail and ears too. See what your cat's meows mean for the common ones.
• Play. A soundboard, whistle tones and games can hold a cat's attention for a short while.

No app can tell you if a new meow means something is wrong; International Cat Care says any change in behaviour could signal a health condition, so talk to your vet. For night-time noise, read why your cat meows at night.

Playing cat sounds to your cat

International Cat Care notes that cats have much more acute hearing than humans or dogs, warns vet clinics that loud and high-pitched noises can be very alarming to a distressed cat, and says even a human “Shhh” sounds like a hiss to a cat.

• Start quietly. For a recorded crying baby, the charity suggests starting at a volume only just audible.
• Keep it optional. A cat should always have free access to an escape route, it says.
• Watch the body. Lowered or flattened ears, a thrashing tail and hiding are among the signs it lists for a cat that is stressed or wants no contact. Stop if you see them.
• Go easy on hisses. If a cat growls, hisses or spits, interactions should stop immediately, it says. We wouldn't play hiss sounds on repeat.

So, do cat translator apps work?

Not as translators. Cats meow mainly at people, meows hint at situation and mood, and in one study a computer sorted meows from three set situations. That is no vocabulary to translate. The best interpreter is still you, watching the whole cat; treat an app as a game and a recorder.

Cat Translator : Meow AI, our app on the App Store and Google Play, records a meow and uses AI to turn it into a playful, human-style phrase: for fun, not a literal translation. A human-to-cat mode turns your voice into playful AI cat sounds; there's also a soundboard of meows, purrs and hisses, whistle tones for training and attention, interactive cat games, and saved sounds to replay. It's free to download; premium features need a subscription you can cancel in your store account. Our FAQ advice: keep the volume low and sessions short, stop if your cat flattens its ears, lashes its tail or hides, and avoid playing hiss sounds over and over.
