A kitten arriving in a new home often does the opposite of what people expect: instead of exploring boldly, many kittens vanish under the nearest piece of furniture and stay there. That's not a bad sign — it's just how a very small animal processes a suddenly much bigger, stranger-smelling world. Here's a realistic picture of the first week and how to help it go smoothly.
Start Small, Not Big
Rather than opening your whole home to a new kitten on day one, set them up in a single, quiet room with food, water, a litter box, a bed, and a few hiding spots (a covered bed or even a cardboard box works fine). This gives the kitten a manageable space to feel secure in before gradually expanding their territory as confidence grows, usually over several days to a couple of weeks. Trying to let a kitten "explore the whole house" immediately often backfires, leading to a kitten who wedges themselves behind the refrigerator and won't come out.
Visit the room often but let the kitten set the pace for contact — sit on the floor, talk quietly, offer a hand to sniff, and let curiosity do the rest rather than reaching in to grab or chase.
Litter Box First Impressions Matter
Most kittens take to a litter box quickly since the instinct to dig and bury is largely innate, but the first week is when habits form. Keep the box in the same small room as the kitten at first, use an uncovered, low-sided box for easy access, and avoid moving it around. If accidents happen outside the box during this settling-in period, it's usually about stress or an awkward box location rather than defiance — our litter box training guide covers troubleshooting in detail if problems continue past the first week or two.
Sleep, Appetite, and Normal Adjustment Behavior
Expect a lot of sleeping punctuated by short, sometimes frantic bursts of play — that's completely normal kitten rhythm, not overstimulation to worry about. Appetite can dip for the first day or so amid the stress of a new environment; keep offering the same food the kitten was already eating, and don't be alarmed by a skipped meal here and there as long as they're drinking water and using the litter box. A kitten who refuses all food for more than 24 hours, however, is worth a call to your vet.
Some kittens hiss, growl, or swat during this adjustment period, especially if they're feeling cornered or overwhelmed — this is fear, not aggression, and it typically fades as trust builds over the following days and weeks.
Introducing Other Pets Slowly
If you have resident cats or dogs, resist introducing them face-to-face on day one. Let the new kitten settle into their small room first, and do initial introductions through a closed door or baby gate so animals can hear and smell each other without direct contact. Slow, supervised introductions over days to weeks go a long way toward a peaceful long-term household, and if there's any hissing or tension, that's a sign to slow down rather than push through it.
Swapping bedding or a small blanket between the new kitten and resident pets before any face-to-face meeting can help everyone get familiar with each other's scent in a low-pressure way. When you do progress to supervised visual contact, keep sessions brief and end them on a calm note rather than letting them run until something goes wrong. Some pairs settle in within days; others take weeks of gradual, positive exposure, and that range is completely normal.
What a Normal First Week Looks Like Overall
By the end of the first week, most kittens have gone from cautious and hidden to at least occasionally curious and playful, even if they're still finding their feet. Don't be discouraged if your kitten seems to take two steps forward and one step back — a confident afternoon of play followed by a shy, hiding day is a completely normal part of the adjustment curve, not a sign that something has gone wrong.
The Bottom Line
A quiet start, a small dedicated space, and patience with hiding, appetite dips, and litter box adjustment will get most kittens through their first week just fine. Confidence usually builds steadily from here, and within a couple of weeks most kittens are exploring, playing, and settling into the rhythm of their new home.
