Invisible to them.
Invaluable to you.

A quiet system that just knows — without watching, listening, or asking your cat to wear anything.

The promise

Sees nothing of you.
Asks nothing of them.

Nothing watches, nothing listens, and there's nothing for your cat to wear or charge. PurrRadar simply reads the WiFi already moving through your rooms, turning the gentle ripples your cat makes into the answer to "where are they?"

No cameras No microphones No wearables
How it sees, without seeing

Your WiFi can feel your cat walking by.

Small sensors quietly talk to each other. When your cat walks by, their body gently disturbs the signal — like a pebble in a pond. PurrRadar reads those tiny ripples and turns them into the answer to "where are they?"

Setting it up

Three small things. Then nothing else to do.

01

Plug in the sensors.

Small, quiet sensors plug into outlets around your home. No drilling, no wiring, no setup tax. Number of sensors depends on the number of rooms and wall thickness.

02

Your cats just live.

No collar to wear. No tag to charge. Nothing for them to notice. PurrRadar reads movement through your existing WiFi.

03

Check whenever you want.

One calm screen on your phone tells you where they are and whether anything's drifted. Nothing more, nothing louder.

Right now, in your home

One glance. You know where they all are.

Open the app and see your home as a quiet floor plan, with each cat softly marked in the room they're in — including the wardrobe, behind the curtains, or under the bed. It updates live.

No alerts unless something needs your attention. Just the answer to "where are they?", whenever you happen to wonder.

Movement, by week

Fewer room-to-room trips over the last 7 days
A quieter, less mobile week often shows up before health changes do at the vet. Worth keeping an eye on.

Normal range. No change.
Health insights

It learns what's normal — then notices what isn't.

Your cat's health, quietly turned into insights.

Cats mask illness. Less roaming, new resting spots, a change in night-time activity — these are the early signs your vet wishes you'd noticed sooner.

PurrRadar reads the baseline quietly over weeks, then surfaces movement shifts as plain-language insights. Something you can show your vet, not a panic notification at 3am.

Three questions, one quiet answer

Every cat owner has asked one of these.

Whether you're home all day or away half the week, with one cat or four, the worry has the same shape.

Once per day, we just lose one of them.

Three cats. A two-story house. Cameras only cover a couple of rooms. The wardrobe, the loft, behind the bookshelf — that's where they actually are. PurrRadar tells you which room, every room, without a collar to wear or charge.

For the multi-cat household

Something's shifting with him, but I can't prove it yet.

Cats mask illness. He's sleeping in new spots, eating a little less, moving differently — small things you half-notice but can't take to the vet. PurrRadar quietly tracks what's normal, so when something drifts, you see it before symptoms do.

For the watchful guardian

I just want to know he's okay when I'm not there.

You travel. The neighbour checks in. The camera shows an empty sofa. PurrRadar gives you one quiet glance from anywhere — a calm "all normal today" — without asking your cat to put up with anything new.

Why we are building this

It started with our own cats going missing.

PurrRadar didn't begin as a product. It began as a problem my wife and I kept running into, every single day, in our own home.

A bigger home, more places to vanish

We moved into a larger house with more rooms and cupboards than we could keep track of — and our cats kept getting lost in it.

The cat who disappeared behind closed doors

One of them, Kimchi, would always sneak into a room — and the moment a door closed, she was nowhere to be found.

When checking every room wasn't possible

When my wife was pregnant, she couldn't easily look under the bed or rush upstairs to find the cats. Checking on them became my job — every time.

The quiet sign something was wrong

While Sobi waited days for dental surgery, she stopped moving — sitting on the same dining chair from morning to night. The stillness was the only signal that she was in pain.

A system like PurrRadar would have answered all of it at once — finding the cats anywhere in the house, letting my wife see where they were without climbing or bending, and catching that Sobi had stopped moving long before we pieced it together ourselves. That's the difference we're building it to make.

Quiet answers

The questions we get most.

Will my cat even notice it's there?

No — that's the whole point. PurrRadar uses the WiFi that's already in your home. There's nothing on your cat, no new sound, no flashing light. The sensors look like small power adapters.

What does it actually tell me?

Which room each cat is in, right now. How that compares to their usual routine over days and weeks. And gentle, specific notes when something drifts — never alarm-style panic alerts.

How long does setup take?

Around ten minutes. Plug in the sensors, open the app, name your rooms and your cats. PurrRadar learns your home's normal over the first few days.

Does it work through walls?

Yes — that's a feature, not a workaround. WiFi signals pass through walls, furniture, and closet doors. Unlike cameras, PurrRadar can sense your cat under the bed or inside a wardrobe.

Is it safe — for cats, kids, everyone?

Yes. PurrRadar uses standard WiFi at lower power than your router or phone. It doesn't add a new kind of signal to your home; it reads patterns in the WiFi already there.

Invisible to them.
Invaluable to you.

A quiet way to always know where your cats are — coming soon.
