Cat City · colony mesh · any city

The city has cats. Now it has a map.

Every city funds stray-cat control. None of them can see the result. Scroll — look at her collar.

The collar

Under 30 grams. Breakaway. Talks to the whole city.

A Meshtastic LoRa node on a breakaway strap: solar strip, GPS on schedule, a buzz motor. Every collar relays for every other collar, pigeon and chimney box in range.

Recall

We don't re-trap collared cats. We call them.

Buzz-before-food. Three weeks of crate acclimation and the buzz means dinner. No cat is trapped twice. The colony comes to the clinic van on its own.

And another

Every cat we fix gets a collar and a name on the map.

Ear-tip is the ID, the collar is the radio. Neutered, vaccinated, chipped, fed, tracked. The number goes down because for once somebody can count.

The colony

Five cats is a mesh. A thousand is a city that can see itself.

Rats get mapped and handed to a licensed operator. Pigeons hold the roofs. People get the jobs, the free text network, and every cat we find is adoptable.

Cat City · by Artificial Mind Hive · PidgeyFlok and AntlerFlok are its programs

One program that empties a city of strays and rats. Humanely, legally, with numbers the council can check.

Fix and track the outdoor cats on a $0/month LoRa mesh, put pigeons on the roofs and receivers on the chimneys, map every rat burrow and hand it to a licensed operator, run the clinic out of a warehouse the city already owns, and staff the whole thing through the city's own job programs. Every piece has its own page.

Cat City

The city has cats. Now it has a map.

Every city funds stray-cat control today. None of them can see the result. Cat City is the map, the mesh and the crew that makes the number go down.

Every cat we fix gets a collar and a name on the map.

Ear-tip is the ID, the collar is the radio. Breakaway only. Buzz-before-food means we never trap the same cat twice: we call it.

Close up

The collar is the whole product.

Breakaway strap, a solar strip, a LoRa radio the size of a thumbnail, a buzz motor for recall. Under 30 grams. It talks to every other collar, every pigeon and every chimney box in range.

All of them

A colony is a network.

Five cats is a mesh. A thousand is a city that can see itself. Every collar relays for the others, so the map fills in from the edges.

01 · Cats

Cats take the streets.

Tracked TNR colonies at street level, breakaway collars, buzz-before-food recall so no cat is ever trapped twice. The layer the city pays for, because it is the one that ends the problem.

The cat program →

Street, roof and sky layers of the mesh
02 · Rats

Rats get mapped, then handed off.

Thermal drone sweeps find every burrow. A licensed operator eliminates; working cats and re-sweeps keep it empty. Chicago spends $12.5-14.9M a year losing this fight.

The rodent program →

Rodent budgets compared
03 · Pigeons

Pigeons hold the roofs.

Owned club birds with 15-gram solar nodes on the ledges cats cannot reach. Three thousand per city, a relay blanket nobody can switch off.

Tagged pigeons on a rooftop ledge
04 · People

People get the jobs and the text.

Caretakers, field techs and builders hired through the city's own programs; a free text network on Lifeline phones for the unhoused; pet food and basic care for owners who need it; every cat we find adoptable.

The mesh

Street, roof, sky: one free network the animals build for you.

Every node relays for every other. A cat in a storm drain reaches a cat on a fence; a pigeon on the ledge hears both; a chimney receiver on Wi-Fi puts it on the map; a drone parked at 400 ft hears the whole district.

Numbers

Cities already spend eight figures a year on the animals. Cat City costs about one percent of that, and it ends.

New York's shelter contract averages $53.7M a year; Miami-Dade Animal Services is $39.7M and holds 500,000 stray cats "steady"; Chicago spends $12.5-14.9M a year on rats and its own audit says the plan is unlikely to work; San Francisco runs Animal Care & Control on $11M. Targeted, tracked TNR has a published end-state: intake down 66 %, euthanasia down 95 % in two years in the treated area.

Five calico cats standing, each wearing a collar node

A colony is a network.

The map fills in from the edges: every collar hears every other. This is the layer the city pays for, because it is the one that ends the problem.

Field notes from the colony

Every city funds stray-cat control today. None of them can see the result.NYC $53.7M/yr, Miami-Dade $39.7M/yr and 500,000 strays "holding steady", SF $11M/yr. The cities' own numbers.
Untracked TNR plateaus. Tracked TNR converges.Targeted TNR in the Alachua study: shelter intake −66 %, euthanasia −95 % in two years in the treated area.
Rats get mapped, then handed off.Thermal drone sweeps find the burrows; a licensed operator eliminates; working cats keep it empty. Chicago spends $12.5–14.9M a year losing this fight.
The warehouse is the clinic.Vet students under a supervising DVM neuter on site; every animal leaves with shots, flea and worm treatment, a chip. A city with an empty building pays less.
People get the jobs and the text.Caretakers, field techs and builders through the city's own programs; a free text network on Lifeline phones; pet food for owners who need it.
Working cats retire indoors.Placed at five or younger, retired to a couch around ten. No cat works for life.

Case study · one big city, one year

$600,000 a year to make the number go down. $40,000,000 a year to hold it steady.Miami-Dade Animal Services FY23-24 vs a full Cat City program: 1,000 tracked cats, 3,000 pigeon nodes, 50 gateways, the clinic, the map. $520,000 if the city lends the building.

A 90-day pilot first: 20 collars, 5 gateways, one neighborhood, a TNR partner who traps and fixes, and a report the council can vote on. Then the city program, written to shrink: years four and five are maintenance, because the population work is finished.

Same radio on the cat at street level, the pigeon on the roof, the deer in the park, the beacon in a hiker's pocket. One network, four couriers, one city that can finally see itself.

Why it ends

Shelters are paid to receive; nobody is paid to work the streets. A tracked colony tells you when it is done, and a done colony is a line item that disappears. Untracked TNR plateaus; tracked TNR converges. That is the whole difference between $40M a year forever and $600k a year for five.

Rules that never bend: no cat trapped or collared outside the partner agreement; breakaway collars only; buzz, never shock; raw GPS stays with the partner and the city; working cats retire indoors around ten.
