Can a Stray Cat Become an Indoor Cat? How to Make the Move

A stray is a cat that lived with people at some point and has since been lost or abandoned. With patience and a safe home, many strays settle back into life as someone’s pet. A feral cat has had little or no friendly contact with people. Adult ferals rarely come to enjoy life indoors.

Behavior usually gives the clearest clues. A stray may come up to people, houses or porches, look at you and blink, meow in reply to your voice, and walk with its tail held up like a house cat. A feral cat tends to keep its distance, avoids eye contact, stays silent, and moves low to the ground with its body tucked in.

These signs are not fixed. A frightened stray in a strange place can behave exactly like a feral cat for a while, and many scared strays relax once they are given time and quiet.

If a cat has a straight, flat tip on one ear, it has almost certainly been neutered through a trap-neuter-return program and probably has a caretaker. Read what TNR is and how it works before deciding anything for that cat. For a frightened adult that has never been handled, staying in its familiar territory with neutering and steady outside care is often the kinder choice. Very young kittens are another matter, as they can learn to trust people early; see what to do if you find kittens.

Before a friendly cat moves in, it is also worth checking that it is not someone’s missing pet. A vet can scan for a microchip, and the found an animal guide walks through the other steps.

At that first visit, a vet will usually give the cat a physical examination and talk to you about testing for feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) before it meets your other pets. The cat will need vaccinations and treatment for worms and fleas, and if it has not been neutered, the vet will plan when to do it. Neutering is especially useful here, because an unneutered cat feels a strong pull to roam and will try hard to get out whenever it senses a possible mate.

Ask about a microchip too. Even in a careful home, no one can guarantee a cat will never slip outside, and a chip improves the chance of getting it back. Treatments and their timing are for your vet to decide.

A spare bedroom or study works well. Check that windows are closed or securely screened and that there are no gaps the cat could squeeze through. Inside, put food and water, at least one litter tray, a bed, scratching posts and several hiding places. A cardboard box on its side or a paper bag is enough. Visit often, and leave a radio on softly when you are out.

Let the cat decide when to come out. Once it is eating, using the litter tray reliably and showing curiosity about the door, you can begin to open up the rest of the home a little at a time. Leave one tray in the original room even after that, so the cat always has a familiar place to go.

Most cats prefer a soft surface they can dig in and bury their waste. Scented litter, deodorizers, hard pellets, crystals and plastic liners often put them off. Many commercial trays are too small for an adult cat. A tray at least one and a half times the cat’s length, such as a large storage box with a low entry cut into one side, is often more welcome. Covered and automatic trays can trap smells and stop a cat keeping watch, which matters to an animal that still feels exposed. For one cat, two trays in different places give it a choice.

Scratching is just as basic a need. It relieves stress and keeps claws in good condition, and outdoors a cat had trees and fence posts for it. Indoors, put sturdy scratching posts in several places so the cat has less reason to use your furniture.

The gentlest way is to change one part of the day at a time. Begin by keeping the cat in overnight. When it has accepted that, extend the time indoors to cover dawn and dusk, then keep it in around mealtimes, and keep lengthening the stretch until it is home all the time. Move to the next stage only when the cat is coping with the current one. If you have been feeding outside, move the bowls indoors. Food, play and attention all help a cat link home with good things.

A securely enclosed outdoor area, if you have the space, gives a roaming cat fresh air and more to do while keeping it safe, and can make the change easier.

Height matters to cats. Shelves, cat trees and perches around 60 to 90 cm (two to three feet) high let a cat look down on its surroundings. A perch by a window is especially valuable, because it turns the street or garden into something to watch.

Hunting can move indoors too. Set aside a play session every day with a wand or fishing-rod toy that the cat can stalk and pounce on, and swap the toys every few days so they stay new. Hiding treats, or part of a meal, around the room or in a puzzle feeder lets the cat search for food rather than finding it waiting in a bowl.

Keep everyday hazards out of reach as the cat gets to know the house: loose wires, medicines, cleaning products and plants that are harmful to cats. If it shows interest in something unwanted, guide it toward a toy or a scratching post instead. Punishment does not work with cats; it only makes them more anxious.

Door-dashing. A cat that has lived outside may wait by the door for its chance. Neutering helps, as intact cats are most driven to escape. Before you leave, give the cat something to do away from the door, such as a treat in a puzzle feeder or a toy tossed across the room. Choose a greeting spot far from the door and say hello and goodbye only there. For a determined escaper, a tall pet pen around the inside of the door creates a simple airlock.

Yowling and restlessness. Calling, especially at night, can come from frustration, from the urge to find a mate in a cat that is not yet neutered, or from stress. Daily play and plenty to do often help. A sudden change in voice or behavior is a reason to check with a vet.

Litter problems. A cat used to soil may need time to accept a tray, and stress alone can lead to accidents. Never punish it. Go back to the room setup above, and see why cats pee outside the litter box for a step-by-step approach.

Scratching furniture. This is normal behavior in the wrong place. Offer posts the cat prefers in the spots it already targets; how to stop a cat scratching furniture explains how.

As for time, every cat is an individual. For a roaming cat, the adjustment to staying home probably takes at least a couple of months. A frightened stray often needs time simply to relax before it shows its real personality. Some cats take a very long time, and a few never cope with life indoors. For a general picture of how rescued pets settle in, see the 3-3-3 adjustment guide.

Watch for these signs of stress or frustration, especially if they last or get worse:

• hiding all the time or withdrawing from people
• grooming far more than usual
• a change in appetite
• toileting outside the tray
• more conflict with other pets
• aggressive or destructive behavior
• much more meowing or yowling than usual

Your vet can check for illness and may refer you to a veterinary behaviorist or a qualified feline behavior consultant. They can also talk through other options for a cat that truly cannot cope with being kept in. Notes on when and where problems happen, and what you have tried, make those visits more useful.
