The first week with a new kitten sets the tone for the rest of your life together, and it rarely looks the way people expect. Instead of a fearless little furball bouncing off the walls, you’ll more likely get a kitten hiding under the couch for two days straight. That’s normal. This guide covers what to actually expect during the first week, what supplies to have ready, and how to tell normal kitten-adjustment behavior from something that needs a vet.
Before Your Kitten Comes Home: The Supply Checklist
Set everything up before you bring your kitten through the door. A kitten arriving to a house with no litter box ready is a recipe for an accident on day one.
- A litter box (low-sided for small kittens) and litter — ask what the shelter or breeder was using
- Kitten-specific food, wet and/or dry, matching what they were already eating
- Food and water bowls, ideally shallow ones
- A carrier for vet visits and travel
- A cozy bed or blanket in a warm, quiet spot
- Scratching post — get one before your kitten decides the couch will do
- A few toys: wand toys, small balls, crinkle toys
- A small, enclosed “safe room” set up in advance (bathroom or bedroom works well)
- A vet appointment scheduled for the first week
Day 1: Start Small With a Safe Room
Don’t let your kitten loose in the whole house right away. Set up one small room with the litter box, food, water, a bed, and a few toys, and let your kitten explore that space first. A brand-new house is enormous and terrifying from a kitten’s point of view, and a smaller space helps them feel like they can actually defend it.
Expect hiding. A lot of it. Many kittens spend their first several hours, or even the first day or two, tucked under furniture or inside a closet. Let them come out on their own terms — sit quietly in the room, let them approach you, and avoid pulling them out from hiding spots.
Night 1: Vocalizing and Restlessness
Some kittens cry at night, especially if they’re recently separated from a mother or littermates. A few things that help:
- Keep the safe room close to where you sleep for the first few nights
- A soft blanket that smells like their previous home or littermates can be comforting
- A ticking clock or a shirt with your scent on it near the bed can mimic the presence of another warm body
- Resist the urge to let a crying kitten roam the whole house at 2 a.m. — a smaller, contained space is safer while they’re still learning the layout
Days 2 through 4: Litter Box Habits and Confidence
Most kittens instinctively use a litter box once they find it, since the behavior is largely inherited from their mother. Keep the box in the same spot, scoop it daily, and avoid moving it during the first week even if the location isn’t ideal long-term. If your kitten isn’t using it consistently:
- Check that the box is big enough and the sides are low enough for a small kitten to climb in
- Try unscented litter — strong fragrances can be a turn-off
- Make sure the litter box isn’t near the food and water bowls
By day two or three, most kittens start venturing farther from hiding spots, showing interest in toys, and approaching you for attention, especially around feeding times.
Days 5 through 7: Expanding Their World and the Vet Visit
Once your kitten is eating, using the litter box, and seems reasonably relaxed in the safe room, you can start opening up access to one additional room at a time. Don’t rush this — a kitten that’s just gaining confidence in one space can get overwhelmed again if given free run of a five-bedroom house too soon.
Schedule your first vet visit within the first week if it hasn’t already happened. The vet will check for parasites, discuss a vaccination schedule, and confirm your kitten is at a healthy weight.
What’s Normal vs. What’s Not
Normal in the first week
- Hiding for hours or even a day or two at a time
- Reduced appetite the first day due to stress
- Some vocalizing at night
- Playful biting and pouncing — this is normal kitten behavior, not aggression
- Sneezing occasionally, especially after a stressful transition
Not normal — call your vet
- Refusing to eat for more than 24 hours (kittens can develop serious liver problems quickly if they stop eating)
- Diarrhea or vomiting lasting more than a day
- Persistent sneezing, discharge from the eyes or nose, or labored breathing
- Complete lack of energy, or a kitten that feels limp when picked up
- Straining in the litter box with little or no output
Tips for Surviving the First Week With a New Kitten
- Let them set the pace. Forcing interaction before a kitten is ready usually backfires and slows down trust-building.
- Keep the household calm. Loud noises, new visitors, and other pets should wait until your kitten is more settled.
- Stick to one food at first. Sudden diet changes can cause stomach upset on top of an already stressful week.
- Introduce other pets slowly, through a closed door at first, over days rather than hours.
FAQ: First Week With a New Kitten
How long does it take a kitten to adjust to a new home?
Many kittens start feeling comfortable within a week, though full confidence — exploring every room, playing openly, sleeping in the open — can take two to four weeks depending on the kitten’s personality and history.
Is it normal for a new kitten to hide all the time?
Yes, especially in the first few days. Hiding is a coping mechanism, not a sign of illness, as long as your kitten is still eating, drinking, and using the litter box.
Should I introduce my new kitten to my resident cat right away?
No. A gradual introduction over one to two weeks — starting with separate rooms and scent swapping before any face-to-face meeting — leads to far better long-term relationships than rushing it.
What should I do if my kitten won’t eat the first day?
A little pickiness on day one is common due to stress. Offer the same food they had before, warm wet food slightly to bring out the smell, and monitor closely. If they refuse food entirely past 24 hours, call your vet.
Final Thoughts
The first week with a new kitten is quieter and slower than most people expect — more hiding, less playing, and a kitten who needs time before they trust you. That’s not a bad sign. Set up a small safe space, keep the routine predictable, and let your kitten come to you on their own schedule. By the end of the week, most kittens are eating well, using the litter box reliably, and starting to show you the personality that made you fall for them in the first place.
