Found a stray cat: is it lost, and what should you do?

Not every cat outside is lost. Many are someone's pet out for a wander, and many cities have community cats that live outdoors and are cared for by neighbors. A few quick checks will tell you whether this cat needs help getting home, needs a vet, or is best left where it is.

Quick checklist

1
Check whether the cat is hurt or in danger. If the cat is injured, very weak or in immediate danger, contact a vet, a local rescue or animal services straight away.
2
Look for an ear tip and a collar. A flat-topped or notched ear usually means a neutered community cat that lives outdoors. A collar or tag means the cat is owned.
3
Look at condition and behavior. A friendly, clean, well-fed cat that seems confused may be a lost pet. A wary cat that keeps its distance may be a community cat.
4
Check for a microchip. Most vets and shelters will scan a cat for a microchip for free.
5
Report the cat. Post a sighting in StraySync so it is checked against lost-pet posts nearby, and ask neighbors.
6
Offer water and shelter if needed. Water is always safe. Avoid cow's milk. Don't move a healthy cat far from where you found it.

First, is the cat hurt or in danger?

If the cat is bleeding, limping badly, struggling to breathe, very thin and weak, or in immediate danger from traffic, call a vet, a local rescue or animal services right away. Approach slowly and calmly; injured cats may scratch or bite out of fear. A towel and a carrier or sturdy box with air holes are the safest way to move one.

Check the ears: what an ear tip means

Many trap-neuter-return programs remove a small tip from one ear, usually the left, while the cat is anesthetized for neutering. It leaves the ear looking flat-topped or notched. An ear-tipped cat is usually a neutered community cat that lives outdoors and may have people feeding it. In most cases the kindest thing is to leave it where it is.

Signs a cat may be a lost pet

A collar or tag is the clearest sign. Without one, look at condition and behavior. A cat that is clean, well-fed, friendly and comes straight to people, but seems confused, hungry or keeps crying at doors, may be an indoor pet that got out. A cat that is wary, keeps its distance and looks comfortable outdoors is more likely to live outside.

Neither sign is certain. When in doubt, treat the cat as possibly lost and spend a few minutes helping its owner find it.

Check for a microchip

Many pet cats are microchipped. Most vet clinics and shelters will scan a found cat for free. If there is a chip, they can contact the registry and the owner. If you can't get the cat to a vet, ask a local rescue whether they can scan it where it is.

Report it and ask around

Take a clear photo and post a sighting in StraySync. Every sighting is automatically compared with lost-pet posts nearby, and if it looks like a match the owner is notified. Also check local lost-pet posts and neighborhood groups, and ask the neighbors closest to where you found the cat. Owners usually start searching close to home.

If you post a found cat elsewhere online, describe it but keep back one detail (for example, a marking or the color of its collar) so you can check that anyone who contacts you is really the owner.

Food, water and shelter

Fresh water is always safe to offer. If the cat is hungry, a small amount of cat food is best. Avoid cow's milk, which upsets many cats' stomachs. In cold or wet weather, a box on its side with a dry towel in a sheltered spot can help.

Try not to move a healthy cat far from where you found it. Lost cats are most likely to be found close to home, and community cats depend on their territory and the people who feed them.

If no owner turns up

Contact a local rescue or shelter to ask about their options. Policies vary by country and city. If you decide to look after the cat yourself for a while, keep it separate from your own pets until a vet has checked it, and keep the sighting active so an owner can still find it.
