Cat lost inside an apartment building: stairwells, garages, and what to ask the manager
Search your own building floor by floor before you go outside, then ask the manager about cameras, empty units, service rooms and who has been moving in or out.
Assume the cat is still in the building
If your cat slipped out of your front door into a hallway, search the building first and the street second. In a large survey of missing cats, indoor-only cats found alive were a median of 39 meters, about 130 feet, from where they got out, and 75 percent were within 137 meters, about 450 feet. That survey did not look at apartments separately, and the owners who answered were not a random sample, but in a building 130 feet is your own floor, the stairwell and the floors above and below. Check your unit again as well, closets and behind the fridge included, since 4 percent of cats in that survey were found in their own home. Then take a flashlight and start at your door.
Work the stairwells floor by floor
Stairwell doors usually close by themselves, so a cat that got in may not be able to get out, and it may have gone up as easily as down. Walk every flight from your floor to the roof door, then down to the lowest level. Look under the bottom flight, behind standpipes, and in any landing corner with stored items. Go again late at night, when the building is quiet. Lost-pet practitioner Kat Albrecht says frightened cats hide in silence and will not meow, so do not treat quiet as a sign that the cat is not there. Speak softly and use a treat bag or food can your cat knows. Do not prop fire doors open. If you want a door held, ask the manager.
What to ask the manager
Go to the office or call the super within the first hour, and bring a photo. Ask these questions in this order. Can you check the hallway, lobby and garage cameras from the time she got out? Which units are vacant or being renovated right now, and can someone look inside? Who has keys to the trash room, mechanical rooms, storage cages, laundry room and roof? Were any movers, contractors or deliveries here today, and did they prop a door? Is pest control booked, and are there traps or bait in common areas? Can you email all the residents today? Camera footage is the most urgent, because it tells you which way to search, and in some buildings it may be overwritten quickly.
The units around you
A cat in the hallway can walk into any open door. In the same survey, 11 percent of cats were found inside someone else’s home. Knock on every door on your floor and the floors above and below, in the evening when people are home. Say this: My gray cat got out into the hallway at about 6 tonight. Could you check your closets, under the beds and your balcony, and look at your laundry room if you have one? Most people will do it if you ask for something exact. Leave a flyer for anyone who does not answer. Cluster mailboxes are off limits for flyers under postal rules, so ask the manager to use the lobby board, the elevator and any resident app.
The garage
Parking garages are full of hiding places a cat can reach, and warm cars are one of them. Dr. Liz Stelow, a veterinarian quoted by CBS News, says cats seeking warmth burrow under cars, under hoods and in wheel wells, including in parking garages in winter. So look under each car with a flashlight, and check tire tops. Ask residents in your email to tap the hood and look before they start the car. Parked vehicles also matter for another reason. Pet FBI lists being carried off in a van among the things that can happen to a cat, so if a cat was seen in the garage and then vanished, ask about delivery and work vehicles that left that day.
If your cat got out from a balcony or window
Then start on the ground directly below, and search outward from there. Look under shrubs, stairs, parked cars and ground-floor patios, and ask ground-floor tenants to check their patios and window wells. An injured cat may hide and stay silent, so look closely rather than calling and moving on. If you find your cat after any fall, take it to a vet right away, even if it seems fine. Then go back to your own building’s side and rear doors, since a cat can slip back inside when someone opens them. Ask the ground-floor tenants and whoever takes out the trash to keep a look out at those doors.
Food, traps and the rest of the search
Ask the manager before you leave food or a trap in a common area, since food can bring in other animals and a surprise trap may be removed. Humane World for Animals says most animal control agencies and many rescue groups lend humane traps, and that they must be watched closely. In a complex with many outdoor cats, Albrecht suggests a non-flash camera at a feeding spot to confirm which cat is coming before you try to trap it. If two days in the building turn up nothing, widen to the block. Our post on what to do when your indoor cat escapes covers the outdoor search.
