Your kitten’s first weeks at home: what’s normal, what to teach, what to watch

Cats 7 min read Published on October 6, 2026

An eight- to twelve-week-old kitten arriving at your home has just lost his mother, his littermates, and every scent he knew. The first two weeks decide a lot: whether he will feel safe, whether he will sleep at night, whether he will bite hands at six months, whether he will accept the carrier and the vet for the rest of his life.

This guide follows the order of the days: the first 48 hours, the nights, the litter box, play and biting, socialization, the scratching post, health, and finally reading what he is already telling you.

The first 48 hours

Set him up in a single quiet room with everything he needs: litter box on one side, water and food on the other, far from the litter, a covered bed or a cardboard box on its side, a scratching post, two or three toys. Put the open carrier in the room and let him come out when he wants. Then sit on the floor and do something else. He will come.

Most kittens hide for a day or two, under the bed or behind furniture. It is normal, and forcing him out only delays things. Discreetly check that he eats, drinks and uses the box, talk to him softly, and let time work. The other animals in the house wait behind the door: introductions come later, by scent first.

The first nights

A kitten who slept in a pile with his litter finds himself alone in the dark: he meows, often loudly, often for a long time. It is not a whim. A warm bed, a wrapped lukewarm hot-water bottle, a cloth that smells of his mother if the breeder gave you one, and a ticking clock or a heartbeat toy help a lot.

The choice that matters: where he sleeps. In your bedroom, he calms down fast and often sleeps on you; it is a choice for years, because a cat who has slept with you does not understand a closed door later. In his room, he cries two or three nights then gets used to it, provided nobody comes at every meow. In both cases, never feed him when he wakes at night: the cat who wakes the house at 4 a.m. for fifteen years started right there.

The litter box

Good news: burying waste is instinctive, and an eight-week-old kitten already knows how. Your job is not to get in the way. An open box, with low sides so he can climb in, fine unscented litter, in a quiet, accessible spot, scooped every day. The rule is one box per cat plus one, in different rooms.

An accident next to the box or elsewhere is never revenge or mischief: it is a message about the box, its location, its cleanliness or its litter, sometimes a sign of stress or illness. Place him in the box after meals and on waking the first days, and read our guide if it persists.

Play, biting and claws

A kitten plays at hunting, and everything that moves is prey: your hand wiggling under the blanket, your feet walking past, your fingers tickling him. If you play with your hands, you teach him that hands are prey, and you will have a six-month-old who bites and scratches to play, with adult teeth. Hands pet, toys hunt, always.

Two sessions a day of ten to fifteen minutes with a wand toy, imitating prey that flees, hides, slows down, and that he finally catches. The session ends with a capture and then a meal: that is the complete hunting sequence, and it is what makes a calm cat. If he grabs a hand or an ankle, freeze, do not yank the hand away, and the game stops for ten seconds. No yelling, no tapping: he would bite more.

The socialization window

The most sensitive period, two to seven weeks, is over by the time he arrives. But everything he meets until about four months stays easier to accept than it will ever be again. Use it to let him experience, gently and with treats, what he will encounter all his life: being carried, having his paws touched and his mouth opened, the carrier left open in the living room with treats inside, the car for five minutes, visitors who ignore him then offer a treat, the vacuum running in another room, calm children.

The first vet visit sets the tone for the next ones: treats in the carrier, calm voice, and if the vet offers a “happy visit” with no procedures, take it. A cat who walks into his carrier on his own all his life is a cat who was trained at three months.

The scratching post, from day one

Scratching is a need, not a flaw: marking, stretching, claw maintenance. If the post is there before the couch, the kitten gets used to it and the couch stands a chance. A stable vertical post taller than him stretched out, a horizontal cardboard one, placed where he lives and near his bed, because cats scratch on waking. Praise every use. Trim the claw tips every two weeks starting now, gently, with a treat: in adulthood it will be a non-event.

Health: what needs a vet

A kitten has few reserves and goes downhill fast. Same day if: he has not eaten for 24 hours, he has diarrhea or vomits several times, his eyes or nose run, he sneezes a lot, he is listless and no longer plays, he breathes fast or with his mouth open, or he struggles to urinate. Within the week after arrival, in any case: a full exam, vaccines on schedule, deworming, parasite prevention, and the microchip if it is not done.

Also talk about spaying or neutering, usually around five or six months, before puberty. It prevents urine marking, roaming, fights and unwanted litters, and does not change the personality, whatever you may have heard.

What he is already telling you

From the first days, your kitten talks to you with his body, and knowing how to read it changes the relationship. The tail up, tip slightly curved, when he comes to you: a happy greeting. The slow blink: “I trust you”; return it. Kneading on your blanket or your lap: the well-being of the fed kitten, kept for life. Flattened ears, lashing tail, dilated pupils during petting: “enough”, to be heeded before the bite.

If a scene puzzles you, film it for ten seconds and read it with Mimo, which takes his age into account. And for the whole vocabulary, our cat body language guide is there.

Frequently asked questions

How long can I leave a kitten alone?

At eight to twelve weeks, a few hours at most, in his safe room, with water, litter and toys. From four months, a workday is fine, provided there are real play sessions morning and evening. A kitten alone all day every day gets bored and often develops play biting and night-time wake-ups.

Should I get two kittens instead of one?

Often, yes, especially if you work outside the home: they play, wrestle and sleep together, and bite humans far less. Two kittens cost more in vet bills and litter, but one bored kitten costs couches and sleepless nights.

When will my kitten stop biting?

Play biting drops a lot around six to eight months, provided nobody played with their hands and he gets his two hunting sessions a day. An adult cat who bites to play is almost always a cat who was allowed to hunt hands as a kitten.

My kitten follows me everywhere, even to the bathroom. Is that normal?

Very normal, and rather a good sign: you are his new safety. The [[q:cat-follows-to-bathroom|bathroom]] in particular fascinates cats, for its closed door and cool surfaces. He will become more independent over the weeks.
