The first 48 hours: a complete bring-home checklist

Do this before your cat is anywhere near the building. Cats orient by smell and territory, and a home that already has food, water, litter, and a hiding spot ready gives them one less thing to be uncertain about the moment they walk in.

Choosing a carrier

A hard-sided carrier with a top that opens, not just a front door, earns its extra cost — it lets you lift a nervous cat out gently from above instead of dragging them out through a small front opening, and makes vet visits considerably less stressful for years to come. Line it with a towel or blanket that carries a familiar scent if you have one available before pickup day.

The core supply list

• A litter box, litter, and a scoop — set up before pickup, not after.
• Food and water bowls, plus a few days of the food your cat is already eating (ask the shelter or breeder what that is).
• A carrier for the ride home and future vet visits.
• A scratching post or pad, placed somewhere visible.
• A cozy bed or blanket that can go inside a crate, carrier, or quiet corner.
• Basic toys — a wand toy and a few small balls are enough to start.

Pick one room first

Before you bring your cat home, choose a single small room — a bathroom, spare bedroom, or home office all work well — and set it up as their base for the first few days. A whole house is overwhelming for an animal who doesn't know where anything is yet, including where it's safe to sleep. Confining them to one room first isn't a punishment; it's the fastest route to a cat who feels secure enough to explore.

While you're setting up, do a hazard pass on that room and the rooms you'll open up next: secure blind cords, tuck away small objects a kitten could swallow, and check for gaps behind appliances a cat could wedge into. Our room-by-room proofing guide covers this in more detail if you have time before pickup day.

Line up a vet before you need one

Choose a vet and save their number before pickup day, not after something goes wrong. If you can, schedule a general wellness visit within the first week — this establishes a baseline for your cat's health and gives you a relationship with a vet before you're calling in a panic. Ask the shelter or breeder for any existing medical records to bring to that first visit.

Carry the carrier directly into the prepared room, close the door, and open the carrier — then leave your cat alone to come out on their own terms. This is the single hardest instruction to follow, because it feels unwelcoming. It isn't. Reaching in to pull a scared cat out, or hovering over the carrier waiting for them to emerge, extends the time it takes them to feel safe.

• Keep the room quiet: no visitors, no other pets, no vacuum.
• Dim the lights if it's daytime and your cat seems tense.
• Sit on the floor at a distance if you want to be present — don't loom over the carrier.
• Let them stay in the carrier for as long as they want. Some cats come out in minutes; others take hours.

If you have kids in the house, this is the hour to set the expectation that the cat gets to choose when it wants attention, not the other way around. A calm first hour sets the tone for the whole first week.

If more than one adult lives in the home, agree beforehand on who goes in and out of the room during this first hour — a rotating stream of well-meaning visitors is more overwhelming than one calm, familiar person sitting quietly nearby.

Your cat should have full access to the one prepared room — and only that room — for at least the first 24 to 48 hours, longer if they still seem anxious. This is where the food, water, litter box, bed, and a hiding spot all live for now, spaced apart from each other (litter box away from food and water, at minimum a few feet).

Expand their territory gradually once they're eating, using the litter box, and moving around the room without hiding constantly — often somewhere between day 2 and day 7. Open one additional door or hallway at a time instead of the whole house at once, and let your cat choose to explore on their own instead of carrying them room to room.

Meeting other pets

Keep any existing pets out of the base room entirely for the first several days. Scent swapping — trading blankets or bedding between animals, or letting them sniff each other under a closed door — is a slower but far more reliable path to a good introduction than a face-to-face meeting on day one.

Once you do allow visual contact, keep the first few sessions short, calm, and supervised, ideally with the new cat still able to retreat behind a door or gate if needed. Hissing or swatting through a baby gate on the first look doesn't mean the introduction has failed — judge progress over days, not a single interaction.

Keep your cat on whatever food they were already eating for at least the first week, even if it's not the brand you eventually want to feed. A sudden food switch on top of a home switch is a common, avoidable cause of stomach upset in the first few days. If you do want to change food, wait until your cat is settled and then transition gradually over 7 to 10 days, mixing in a little more of the new food each day.

Some cats won't eat much in the first 24 hours — that's typical and rarely a concern on its own. Going longer than 24 hours with no food at all is different and needs a closer look; see when to call a vet below. Keep fresh water available at all times, placed away from the litter box, and wash bowls daily.

Bowl material matters more than it seems: plastic bowls can trap bacteria in fine scratches over time and are linked by some vets to chin acne in cats prone to it. Stainless steel or ceramic bowls are an easy, inexpensive swap and are simpler to keep genuinely clean.

If your cat is still a kitten, feeding frequency and portions change quickly as they grow — our feeding schedule by age guide breaks down exactly how much and how often at each stage. The Kitten Feeding Planner is a printable way to track it once you're past the first 48 hours.

Most cats use a litter box without any training at all if it's accessible, clean, and in a quiet location — the instinct to bury waste is already there. Use an unscented, fine-grain clumping litter to start; scented litter and heavily textured litter are the two most common reasons a cat avoids the box.

• One litter box per cat, plus one extra, is the standard rule of thumb.
• Scoop at least once a day — cats are far more likely to avoid a dirty box.
• Place boxes in low-traffic, easily accessible spots, never right next to food or water.
• Avoid a covered box or a liner at first; both are more likely to be a barrier than a comfort for a new cat.

If your cat came from a shelter or foster home, ask what litter they were already using and start with the same one — you can switch gradually later. For step-by-step troubleshooting if litter use doesn't click right away, see our full litter box training guide.

Box size and depth

A box that looks plenty big in the store is often too small once it's in use — a good rule of thumb is a box at least one and a half times your cat's body length, so they can turn around and dig comfortably. Fill it two to three inches deep; cats who aren't digging or covering well sometimes just don't have enough litter to work with.

Hiding is a normal, healthy stress response — not a sign that something is wrong. Give your cat at least one enclosed space in the base room where they can't be seen: a covered bed, an open box turned on its side with a blanket, or the space under a bed. Don't remove or block access to a hiding spot to force interaction; that tends to backfire and slow down trust-building.

It's common for a cat to spend most of the first few days hidden, coming out to eat and use the litter box only when the room is quiet. Most cats start voluntarily spending more time out in the open somewhere between day 3 and day 14. Slower than that isn't necessarily a problem either — some cats are simply more cautious by temperament.

Resist the urge to check on a hiding cat too often. Repeatedly opening the door, calling their name, or peeking under the bed every hour reads as pressure, not comfort, even when it's well-intentioned. A better approach is checking food, water, and the litter box a couple of times a day and otherwise letting the room stay quiet and predictable.

Close the base room door overnight rather than giving your cat the run of the house. It's tempting to leave the door open so they don't feel “trapped,” but a confined, familiar space is calmer for most cats on night one than an entire unfamiliar house in the dark.

• Leave a small night light on if the room has no natural light source.
• Don't be alarmed by activity overnight — cats are naturally more active at dawn and dusk.
• Resist checking on them repeatedly; let them settle.
• If you hear vocalizing, it usually settles within the first couple of nights as the routine becomes familiar.

If you have young children, the first night is a good time to set a firm rule that the cat's room is off-limits once the door is closed for the night. A consistent boundary here does more for long-term trust than any single toy or treat.

Most rough first weeks come down to a handful of avoidable missteps rather than anything being “wrong” with the cat.

Adjustment stress and a genuine medical issue can look similar in the first 48 hours, so it's worth knowing the difference. Normal adjustment includes hiding, reduced appetite, and lower activity that gradually improves day over day.

Cats from shelters or multi-cat foster homes are also more likely to be incubating a mild upper respiratory infection, which can show up a few days after a stressful move. Sneezing, mild eye or nose discharge, and slightly reduced appetite call for a check-in with your vet, even if your cat otherwise seems comfortable — it's a frequent, usually straightforward diagnosis when caught early.

For a broader reference on what's normal versus what's not during the adjustment period, see signs of a sick kitten. Save your vet's number and the nearest emergency clinic before you need them, not while you're searching for it — the Cat Emergency Sheet is a free, one-page template for exactly that, and the Emergency Cat Care Planner extends it into a full medical history log.

Use this as a quick reference once the setup is done and the two days are underway — everything here is covered in more depth in the sections above.

Print or save it somewhere you'll actually look at it during the first two days, rather than relying on memory in what's often a busy, slightly overwhelming stretch.

Before pickup day:

1. Set up one base room with litter box, food, water, bed, and a hiding spot.
2. Do a hazard check of that room and any adjoining rooms.
3. Buy a carrier, scratching post, and a few basic toys.
4. Confirm what food and litter your cat is already using.

During the first 48 hours:

1. Let your cat exit the carrier on their own terms in the base room.
2. Keep them confined to that one room, expanding space gradually.
3. Keep their existing food and litter unchanged for now.
4. Scoop the litter box daily and keep water fresh.
5. Leave hiding spots accessible and don't force interaction.
6. Close the base room door overnight.
7. Watch for the vet warning signs above, not just general shyness.
