Cat collar tag + app
Mewsense listens to meows and reads tail, ears and blinks to tell you the likely mood and context — a read on feeling, not a word-for-word translation.
The 2am meow
Cats don't meow at other cats much; they save it for us. But one owner can't tell "feed me" from "my stomach hurts" by ear alone, and getting it wrong has a cost.
This part is proven: cats slow-blink back at owners who slow-blink first, and approach more readily afterward (Humphrey et al., 2020). Mewsense watches for cues like this one too.
How it works
A coin-sized tag on the collar listens for meows, purrs, trills and hisses.
The app's camera reads tail, ears and eye behavior for a few seconds.
"Likely annoyed, give space" or "wants food" — tuned to your cat over time.
Features
Learns the specific meows, trills and hisses of your cat, not a generic cat.
Camera-based tail, ear and slow-blink reading, added to the sound.
Flags mealtime, vet visits, new guests and night-time differently.
Every confirmed read refines the model for that one cat.
Audio and video are read on-device by default, not streamed out.
Daily reads turn into patterns — what sets your cat off, what calms them.
Why it works
Cats half-blink and narrow their eyes more after an owner slow-blinks at them, and approach a stranger more readily after one too.
Humphrey et al., 2020, Scientific Reports →Listeners sort meows into situations above chance — better if they've lived with cats. Separately, Lund University's Meowsic project studies the melody cats use with people.
Nicastro & Owren, 2003, J. Comparative Psych. →A classifier trained on meow acoustics told apart "waiting for food," isolation and brushing contexts better than simpler baselines.
Ntalampiras et al., 2019, Animals →Honest limit: none of this research shows cats or meows encode specific words. Mewsense estimates mood and likely context from sound and body language — it does not translate language, because cats don't have one in that sense.
Who it's for
First cat, first crying jag. Mewsense flags "likely hungry" vs. "likely scared" so the guessing stops.
Three cats, one hissing match. Context tags show who's defending territory versus who's just startled.
An older cat's meows changed. A mood log makes "off lately" something you can actually show the vet.
The slow blink is one cue among many Mewsense tracks — it's not the whole picture, which is the point.

FAQ
No. Cats don't speak in words we could translate. Mewsense reads sound and body language to estimate mood and likely context — "wants food," "annoyed, give space" — not a sentence.
Published research shows meows carry real but modest context signals, stronger for people who already know cats. Mewsense's job is to do that reading more consistently, not perfectly.
On your phone, by default. Clips aren't uploaded unless you choose to share one with us to help improve the model for your own cat.
No. The tag only listens for sound. It isn't a GPS tracker.
No. Mewsense can flag a change worth mentioning to your vet. It isn't a medical device and makes no diagnosis.
Each cat gets a separate learned profile once you add a second tag, so reads stay specific to each one.
