Bringing Home a Kitten: The First Month

Bringing home a kitten is nothing like bringing home an adult cat. An adopted adult usually hides, and your job is to leave her alone and wait. A kitten is the opposite: she’ll tumble off the back of the couch, wedge herself under a recliner, and hunt a hair tie across the floor. What takes the most effort these weeks is keeping up with her, keeping her safe, and making the most of what you can teach her over the next little while, because a developmental window is already quietly winding down the moment she walks through your door.

A kitten is not a small adult cat

It’s easy, the first time, to treat a kitten as a smaller version of an adult cat: same food, same gear, just smaller portions. That assumption is behind a lot of first-time mistakes. A kitten between 8 and 16 weeks is still in a once-in-a-lifetime developmental stage, and much of her socialization, her play behavior, and her sense of what counts as a “normal world” is being laid down in these few weeks. What you do now will shape who she is at three years old.

This article focuses on kittens between 8 and 16 weeks, just separated from their mother and starting to live on their own. If yours is younger than 8 weeks, she’s better off staying with her mother; that stage calls for bottle-feeding, keeping her warm, and intensive hand-rearing, which is a different job. If she’s older than 16 weeks, most of this still applies, but the time pressure is far lower, and you’ll probably get more out of the first month with an adopted cat.

Before she comes home

When to take her home

How old a kitten should be when she comes home depends mostly on whether she grew up with her mother.

With a mother, later is better. Whether it’s a breeder, a shelter mom-cat with her litter, or a rescued TNR litter, as long as she still has her mother and siblings around, let her stay a while longer. A 2017 study of 5,726 cats found that kittens separated from their mothers before 8 weeks were noticeably more likely to show aggression and stereotypic behaviors (like overgrooming) as adults, and the fewest behavior problems were in kittens taken home at 14 to 15 weeks. Twelve weeks is a reasonable floor; 14 is better.

A kitten without a mother around is a different case. There are lots of reasons: she may have been abandoned, found on her own during TNR, separated from her mother, or lost her too early. The “wait until 12 weeks” rule doesn’t apply to her. Keeping her in a shelter cage to “make it to 12 weeks” only costs her weeks of human contact, which works against her socialization. For these kittens, two things matter more than age: whether she got real human handling between 2 and 9 weeks, and whether she’s physically ready to come home (eating dry food on her own, stable weight, first vaccine done). Most shelters open these kittens for adoption around 8 weeks.

Either way, before you take her, talk to the foster carer or breeder about her life so far: how often she’s been held, whether she’s used to having her paws touched and her mouth looked at, whether she’s heard the vacuum and the doorbell, which people she’s met. That tells you more about her foundation than her age does. A kitten who’s been held often and raised well from the start will usually warm to you faster, even at 8 weeks, than one who sat in a cage until 12 weeks with little handling.

Supplies

You don’t need to buy out the pet store, but kittens have a few things adults don’t.

Kitten-proof the house, properly

Kitten-proofing needs to go further than cat-proofing for an adult. An adult cat roughly knows what she can climb and what she shouldn’t do; a kitten doesn’t. Walk through the house before she arrives and deal with these:

• String and thread: yarn, hair ties, ribbon, dental floss, tinsel, sewing thread. A swallowed string can do real damage: one end catches while the intestines pull the rest tighter, which can badly injure the gut and often means surgery. Cats are especially prone to going after string. Get all of it out of reach, and check under the couch.
• Recliners: a kitten climbs up into the mechanism and can be crushed when someone sits down or leans back. If you have one, make it a rule to check where the cat is before adjusting it.
• Toilet lids: kittens fall in and can’t climb out. Keep the lid down for the first few weeks.
• Looped blind and curtain cords: a strangulation risk. Cut the loops or move them out of reach.
• Washing machines and dryers: doors always closed, and check again before every load.
• Balcony gaps: kittens fit through smaller gaps than you’d think.
• Small objects: coins, beads, earring backs, small Lego pieces, rubber bands.
• Toxic plants and foods: lilies are especially dangerous, a single lick of pollen can cause acute kidney failure, so move the whole plant out of the house rather than just “up higher.”
• Cleaning products: in a cabinet that closes, not under the sink.
• Dangling cords: from blinds, lamps, and electronics; kittens chew them.

The list looks long, but most of it is the kind of thing you don’t think about until something goes wrong. Doing it once before she arrives is far easier than fixing it afterward.

The first day

Most kittens don’t hide for long. Some poke their head out of the carrier the moment they arrive, do a lap of the room, and jump into your lap; others hide under the furniture for half a day before coming out. Both are normal.

For the first day, give her one small room as a base. Not because she’s fragile, but because the moment you let her loose in the whole house, you won’t be able to keep track of her. A spare bedroom or a study is fine, door closed. Put her food, water, litter box, a scratcher, and a few toys in there, sit on the floor, and let her decide when to come out and find you.

Once she’s relaxed in the small room, you can open up the rest of the house, usually within a few hours, at most by the next morning. The first time she explores another room, follow behind her and leave everything else for later. This is usually when you spot the kitten-proofing you missed.

A lot of kittens cry the first night. She’s just left her mother, her siblings, and every smell she knew, and it’s normal for her to feel unsettled. Whether you keep her in a room to settle on her own or let her sleep next to you, either is fine, there’s no single right answer. Put a piece of bedding from her old home next to her (don’t wash it, keep the scent), keep the room quiet and dim, and most kittens settle within a few nights. After that she may sleep 18 to 20 hours a day, and the occasional 3am zoomies are normal too; for her rhythms and how to handle them, see the cat sleep guide.

The socialization window: get her meeting the world early

Kittens go through a stretch where they’re unusually open to new things. Behaviorists call it the sensitive period, and it runs roughly like this:

During this time she’s making sense of the world: which people, sounds, animals, and places count as safe. The earlier she meets them, and the safer she feels at the time, the more easily she’ll treat them as ordinary parts of life once she’s grown.

(If she doesn’t come home until after 12 weeks, that’s not too late at all. The extra time with her mother and littermates buys a different but equally important foundation: she’s more settled emotionally and better at controlling how hard she bites. It’s kittens taken from their mother too early who tend to grow up more anxious and bitey.)

What you do at home is simple: keep letting her meet the everyday things she’ll run into as an adult, and keep each encounter pleasant and unforced. No training, no commands, she just needs to feel safe in the moment. The things to introduce her to fall into a few groups.

• People who aren’t you: one or two friends over is plenty, don’t throw a party. Have them sit on the floor with a few treats, and let her hide if she wants. The point is for her to feel that strangers are nothing to be afraid of; whether the visitors like her is beside the point.
• Handling: hold her gently, touch her paws, open her mouth to look at her teeth, brush her a few strokes with a soft brush, trim one nail at a time with a treat, pop her in the carrier for five minutes to eat a meal. You’ll be doing these every few months for the next fifteen years. Get her used to them now, and nail trims and carrier trips stay easy.
• Household sounds: the vacuum, the doorbell, the blender, the TV, the sounds of cooking. Don’t come at her with the vacuum running; let her hear it from a distance, on low, with treats nearby, and close the gap slowly.
• The carrier and the car: take her on a short car ride, anywhere, as long as it isn’t the vet. Treat when you get home, and do it again next week. A cat who learns young that the carrier doesn’t always mean the vet is far easier to live with for the next fifteen years.
• Other animals: if you have a dog, or a cat already, follow the slow introduction routine for multi-cat homes. Kittens adapt faster than adults, but don’t skip the steps.

There’s evidence behind all this. A UK shelter study found that kittens handled and held more between 2 and 9 weeks were less fearful of people a year later, and more bonded with their owners. Small sample, but the finding was clear.

Just don’t overdo it in your eagerness to get it right. One badly frightening experience during this period can leave her with a lasting fear of whatever caused it, which is worse than doing nothing. So keep it relaxed: gentle each time, often, always paired with food or play, and always leave her a way out.

Feeding and growth

Kittens need more calories, protein, and fat than adult cats, and the gap is biggest when they’re youngest. Feed kitten-formula food for the whole first year, and don’t switch to adult food too early; she’ll be underfed and may grow up smaller. Feed small, frequent meals: three to four a day when she’s little, dropping to two as she nears a year. For portion sizes and when to switch foods, see the cat feeding guide.

Weigh her once a week on a kitchen scale and write it down; what you’re looking for is a steady upward line, and a flat or falling one is a vet visit. One common myth worth clearing up: a healthy 8-to-16-week-old kitten can go a whole night, or miss a meal, without trouble. One study followed 75 kittens this age through an overnight fast and not one became hypoglycemic. (The kittens who really do need feeding every few hours are neonates under 6 to 8 weeks.) An occasional skipped meal is nothing to panic over; several refused meals in a row is the sign that means call the vet.

Vaccinations and medical care

Over the next few months she’ll get a series of vaccines, starting at 6 to 8 weeks, one every few weeks, running until after 16 weeks. Why so many? The antibodies passed down from her mother block the earlier shots, and because those antibodies fade at different times in different kittens, only by boostering past 16 weeks can you be sure at least one dose has actually taken. The full schedule, what each vaccine does, and the rabies rules where you live are all in the complete cat vaccination guide.

Book her first checkup within a week or two of coming home. Besides setting up her vaccines, the vet will give her a physical exam, check a stool sample, and deworm her; even from a good shelter, kittens often come home with intestinal parasites. You can also raise spay/neuter at this visit, usually somewhere around 5 to 6 months. Bring any past medical records with you.

How to play with her

Kittens play rough. Wrestling, chasing, pouncing, and biting are all normal cat play, really just their built-in hunting instinct getting its practice. Your job is to show her where the line is.

The single most important rule: don’t use your hands or feet as toys. Fingers wiggling under a blanket are great fun to a 10-week-old kitten, but once she’s a 5kg adult, the same move becomes ambushing your ankles, and by then it’s hard to undo. Use a wand toy, a throw toy, or a long stick instead, anything that keeps her teeth away from your hands and feet. If she bites your hand mid-play, end the game right there, stand up and walk off; a few repetitions and she gets it.

Two sessions a day, ten minutes each, is plenty for most kittens. The key is to let her actually catch the prey a few times; how long you play matters less. A cat who can always see the target but never catch it gets frustrated. Laser pointers are the classic example: one survey found that cats who play with lasers a lot are more prone to repetitive behaviors like staring at lights and shadows, mostly because they can chase but never catch. If you do use one, finish by tossing a treat or a toy where the dot vanished, so she has something real to catch.

One kitten or two?

Two kittens are often less work than one, not more. They play with each other, wear each other out, and keep each other company while you’re out, which is a lot for one owner to cover alone. If you have any room in your space and budget, bringing home a bonded pair from the same litter is one of the easiest choices you can make.

One is fine too, but be honest about the extra time it takes: more interactive play, more regular handling, and ideally regular contact with a healthy, indoor-only adult cat. A single kitten, a quiet apartment, and an owner who’s often out is the hardest combination. And if you already have an adult cat, two new kittens are actually easier than one, because the pair entertain each other instead of latching onto your resident cat, and being latched onto is exactly what the resident cat likes least.

When to worry

A lot of what looks alarming in a kitten is actually normal. Passing out cold after a wild play session, hiccups, and briefly soft stool during a food change are all common, and the odd small vomit is acceptable, but repeated or ongoing vomiting isn’t.

Reasons to call the vet the same day:

• Low energy that a short rest doesn’t fix. A kitten with no interest in a toy at all isn’t right.
• Not eating across two or more meals.
• Ongoing diarrhea, especially with blood or a bloated belly. Parasites are common in kittens and treatable, but they need to be diagnosed first.
• Repeated vomiting.
• Labored breathing.
• A belly that’s swollen, hard, or painful to the touch.
• Limping that doesn’t improve within an hour.
• A string or thread hanging from her mouth or rear. Don’t pull it. This is the swallowed-string danger from earlier, go to a vet right away.

The hardest month, and the most rewarding

The first month is the most intense, but it isn’t the whole job. After it, she’ll shift from a fully-charged little motor to something more like a cat, and her socialization keeps winding down gradually rather than ending abruptly at week four. A few things are worth keeping up: once a week, put her in the carrier to eat a meal, or take her on a short trip that isn’t to the vet, so the carrier never comes to mean only the vet; nail trims, brushing, and checking her teeth need only a few seconds and a treat each; and don’t stop the two play sessions a day.

Looking after a kitten is a matter of following her around, showing her the world and keeping her safe while she’s still learning to run her own body. It asks for stamina and attention. But the few weeks you put in now go a long way toward who she is at three. Before long you’ll start noticing small things that warm you: she comes running at the sound of the food bag, sits still for a nail trim, walks over to greet visitors, climbs into your bed at night on her own. None of that just happened; it grew out of the weeks when doing the work paid back the most.
