Photographing cats
Why a photo of a cat on a screen is not a cat
A photograph of a cat on a screen is flat, backlit and full of tells, and refusing it is the one decision I am least willing to soften.
Cat behaviour
A cat turns up at your door or follows you on a walk: the internet calls it the cat distribution system. The joke is about being chosen; the practical next step is checking whether that cat already has a home.

The short answer
The cat distribution system is an internet joke about a cat appearing in someone’s life unexpectedly, as if it had been assigned to them. It is a meme, not a real service. A friendly cat approaching you does not prove it is unowned: check for an existing home before treating the encounter as an adoption.
People use the phrase for an unexpected cat encounter that becomes a story: a kitten found near a workplace, a visitor at the door, or a cat that keeps joining a regular walk. Cat delivery system, kitten distribution system and cat allocation system are variations on the same joke.
A keepsake does not have to mean keeping the cat. Take a respectful photo, then make a decorative card from a photo you own, or record a live encounter in PoCats. The browser tool does not create an in-app catch.
A cat you have never seen before comes out from under a parked car, crosses the pavement at an angle, and sits down about a metre from your feet. It does not run. It looks at you and waits. Somewhere in the back of your head a small voice says: this one is mine now.
That is the moment the cat distribution system names. The system has decided you are due a cat, and the service doing the deciding is invisible, unaccountable and slightly smug. You do not choose. You receive a delivery.
It is a good joke because it is nearly true. Cats really do end up living with people who had no plans for a cat. What the joke leaves out is the part that matters. The cat had reasons, most of them physical and boring, and there is a decent chance it already has a name and a bowl two streets away.
The phrase spread through social media in the early 2020s, mostly on TikTok, Twitter and Reddit, and no single person is credited with inventing it. It caught on because it named something people had already noticed and had no word for: cats arrive. A kitten under a bonnet. A cat that walks into the pub and stays. One that follows you home from the bus stop and then, somehow, is still there in the morning.
The name bends to fit the case. A litter found in a shed in May is the kitten distribution system. Someone being formal says feline distribution system. Cat delivery system, cat allocation system and cat selection system all turn up too, mostly from people who want it to sound like a government department. It is one joke with several labels.
The framing also does a quiet, kind job. If the cat was assigned to you, nobody has to justify the vet bill, the ruined sofa or the sudden change of plans. You were selected. You were only obeying the system.
Two ordinary things sit underneath the magic. The first is arithmetic. In most towns there are cats outside at any hour: pets allowed to roam, cats living around bins and sheds and garden decking, and kittens born through spring and summer. If you walk the same streets often enough, you will pass cats. Nearly all of them will ignore you. You will forget every single one of those.
Then one does not ignore you, and that one becomes a story. Nobody tells their friends about the eleven cats that looked up and walked off.
The second thing is that cats approach people for readable reasons, and the reasons are not mystical.
People often say cats go to whoever in the room is ignoring them. There is a simpler version of that. The person ignoring the cat is the one who is not looming, not reaching, not staring and not calling. They are not charming the cat. They are just doing none of the things that make a cat leave.
This is the part the joke skips, and it is the part that decides whether your good intentions help or hurt. A confident, friendly cat wandering about in the afternoon is far more likely to be somebody's pet on its rounds than an animal with nowhere to go. Before you decide the universe has sent you a cat, read the cat.
| What you can see | What it usually means |
|---|---|
| Clean coat, good weight, no ribs showing | There is a food bowl somewhere. Cats living rough are rarely glossy. |
| A collar, or a band of flattened fur around the neck | Owned. Collars come off, but the mark in the fur takes a while to lift. |
| A neat notch or a straight-cut tip on one ear | Neutered and returned through a trap, neuter and return scheme. It is a permanent mark made under anaesthetic so the same cat is not trapped and operated on twice. |
| Keeps its distance, will not be touched, seen mostly at dawn and dusk | Probably an unowned cat that has never lived with people. Kindness here is food, shelter and a call to a rescue, not a lap. |
| Thin, matted, crusted eyes, limping, or breathing badly | Needs a vet today, whoever owns it. |
| A very small kitten on its own | Watch from a distance first. Mothers move litters one kitten at a time and are often back within the hour. |
Putting food down is the moment the joke stops being a joke. Cats return to a reliable food source, and they are not discreet about it. One saucer on a doorstep becomes a queue within a fortnight.
If the cat is somebody's pet, a second dinner quietly removes the owner's best early warning. Appetite is the first thing to change when a cat is unwell, and a cat being fed at three houses never looks off its food at any of them. Some cats are on prescription or restricted diets for kidney, weight or digestive problems, and your kindness undoes the vet's work.
If the cat is unowned, food alone does not neuter it, vaccinate it or treat it. Cats can start breeding from around four to six months old and a female can have more than one litter in a year, so a fed group that is never neutered simply becomes a bigger fed group. Feeding without a rescue involved is the half of the job that feels good.
Two rules that never bend. Do not put food anywhere that draws a cat across a road, including your own side of a busy street. And no milk: most adult cats cannot digest it properly and it gives them an upset stomach. Water is the correct drink.
If you do decide to feed, feed a measured amount at a set time, stay and watch, and use those minutes to start looking for an owner rather than becoming one.
Never corner, chase, grab or trap a cat with your hands, and never step into a garden or a yard that is not yours to reach one. A frightened cat bites and scratches, and both of you come out of it worse. If a cat wants to leave, let it leave. It knows where you live now.
There is a real distribution system and it is not funny or magical. It is neutering, because unneutered cats produce the kittens that later arrive on doorsteps. It is microchipping and, just as importantly, keeping the chip details up to date when you move house. It is the volunteers who run trap, neuter and return schemes on the same estate for years. It is people bothering to report a found cat instead of quietly keeping it while a family two streets away puts up posters.
Every cat that gets home does so because somebody did the dull version of the joke.
Most of the cats that pick you are not for taking home. The tabby that sits on the wall outside the chip shop has a house, a name you will never learn and a routine you have wandered into. The black cat on the postbox will let you make a fuss of it for ninety seconds and then be finished with you. That is the whole relationship, and it is a good one.
That is the part I wanted to keep, which is why PoCats exists. It is a free iPhone and Android game about the cats you meet outdoors: you photograph a real cat, the photo is checked to confirm a live cat and cut it from the background, and that cutout is the card in your album; nothing draws the cat. No adverts. The cats stay exactly where they live.
The best possible outcome of a cat walking up to you is not a new cat. It is a cat that gets home, and a photograph of the two minutes you spent together on the pavement.
It is an internet meme about cats unexpectedly arriving in people's lives, as if an invisible service had assigned them. It is not a real organization or an adoption process.
The joke is not; the behaviour is. Cats really do approach people who are still, low and not staring at them, and a great many of the cats that seem to choose someone already have an owner a few doors away. The system that actually gets cats home is the dull one: neutering, a microchip with up-to-date details, and reporting a found cat instead of quietly keeping it.
The same joke under different names. Cat distribution system is the common form; cat delivery system, cat allocation system and cat selection system turn up as well, and all of them mean a cat arrived in your life without being asked for.
Usually because of what you are not doing. Standing or sitting still, keeping your head low, avoiding long eye contact and letting the cat close the last gap all read as harmless to a cat. Taking the same route at the same time also helps, since cats keep territories and timetables and quickly treat regulars as part of the furniture.
Check for a collar and tag, photograph the cat, and ask at the nearest houses, since most found cats live within a few streets. Then get it scanned for a microchip at a vet practice or rescue centre, which is free and takes seconds, and post the photo and location on local lost and found pages. If the cat is injured, very thin or a young kitten, go to a vet straight away rather than waiting.
Be careful, because feeding is a commitment rather than a one-off kindness. If the cat is someone's pet, a second dinner hides the earliest sign of illness and can undo a prescription diet; if it is unowned, food alone does not neuter, vaccinate or treat it. Never put food where it draws a cat across a road, never give milk, and contact a local rescue as well as feeding.
Make a keepsake with the cat card maker, using a photo you own. For your next walk, the body language decoder reads a cat's tail, ears and eyes back to you, and the street cat name generator names the one that has been sitting on your wall all summer.
PoCats is a cat spotting game: you photograph a real cat you meet, it is checked as a living animal, and it becomes a collectible card cut from your own picture. The catch itself is a two-second timing moment you can try in your browser, and the whole loop is explained here.

Cat behaviour
Most people greet a street cat by walking straight at it. Here is the slower way that actually works, and the signals that tell you to stop.

A cat tells you what it wants with its tail, ears, whiskers and eyes, usually several seconds before you get close enough to make a mistake.
