New Kitten First Week Checklist (USA 2026)

The first 48 hours: one room, not the whole house

A kitten that just left its mother and littermates is tiny and overwhelmed, and a whole house is too much space at once. Start it in a single quiet room with a litter box, food and water, a bed, and a couple of hiding spots — a cardboard box on its side works fine. Let the kitten come to you rather than chasing it out from under the couch. Keep feeding whatever the shelter or breeder was using for at least the first several days; changing food on top of a stressful move is a reliable way to cause diarrhea, and diarrhea dehydrates a kitten fast. Expand its territory to the rest of the home over several days once it's eating, using the box, and coming out to play.

Your first-week priorities

The first vet visit — what happens

Book it early: Most vets want to see a new kitten within the first week home. The exam is a nose-to-tail physical: they weigh the kitten, listen for a heart murmur, check the mouth for a cleft palate, feel the belly for a hernia, and look in the ears — ear mites are extremely common in kittens and cause that dark, crumbly gunk. Bring any paperwork from the shelter or breeder and, if you can, a fresh stool sample. If you already have a cat at home, keep the newcomer separated until this visit clears it.

FeLV/FIV test, parasites, and vaccines: The AAFP recommends every newly adopted cat be tested for feline leukemia (FeLV) and feline immunodeficiency virus (FIV) regardless of age, because both change how you house and care for the cat — a simple in-clinic blood test usually runs about USD 30–60. If the kitten is under about 9 weeks, your vet may repeat the test later to confirm. Intestinal worms are nearly universal in kittens, so expect deworming even if the stool sample looks clean. The core FVRCP vaccine series starts around 6–8 weeks and repeats every 3–4 weeks until at least 16 weeks, with rabies added around 12–16 weeks and required by law in many states.

Litter box and food — get these right in week one

Litter box: Kittens are close to hardwired to use a box, so the trick is just making it obvious and easy. Use a shallow, low-sided tray a tiny kitten can climb into, and start with plain, unscented, non-clumping litter — very young kittens taste-test everything, and clumping litter can clump inside them if swallowed. Switch to unscented clumping litter around 8–10 weeks. Put the box somewhere quiet and away from the food bowls, and follow the standard rule of one box per cat plus one extra. If accidents happen, it's usually the box being too far, too tall, or too dirty — not defiance.

Food: Feed a food labeled for "growth" or "all life stages" that meets AAFCO standards — kittens need more protein and calories than adults (roughly three times the calories per pound), and adult food won't cut it. An 8- to 12-week-old does best on about four small meals a day. Use the amount on the package as a starting point and let your vet fine-tune it to your kitten's body condition. Have fresh water out at all times; many cats drink more from a wide, shallow bowl or a pet fountain.

Kitten-proofing: the hazards cats find that dogs don't

Kittens climb, squeeze into gaps, and bat at anything that dangles — so the danger list looks different from a puppy's. Before the kitten explores, deal with these:

• Lilies (Lilium and Hemerocallis — Easter, tiger, day, Asiatic): every part is lethally toxic to cats, and even licking pollen off a paw or drinking vase water can cause fatal kidney failure. Keep them out of the house entirely.
• String, yarn, ribbon, tinsel, hair ties, and dental floss: swallowed, they become "linear foreign bodies" that can saw through the intestine and need emergency surgery.
• Electrical and blind cords: chewing risks a burn or shock; looped blind cords are a strangulation hazard.
• Window screens and high balconies: kittens push through loose screens — vets call the result "high-rise syndrome." Check that screens are secure.
• Recliners, washers, and dryers: kittens hide in warm, dark spaces. Slap the dryer drum and check under recliner footrests before using them.
• Small swallowable objects and human medications: keep pills, rubber bands, and small toys well out of reach.

None of this requires a renovation — mostly it's moving plants outside, tucking cords away, and getting in the habit of a quick glance before you close an appliance or push in a recliner. Program your nearest 24-hour emergency vet and the ASPCA Animal Poison Control number (888-426-4435) into your phone now, before you need them.

What to buy (and rough US costs)

• Litter box (low-sided) plus unscented litter: USD 15–40
• Kitten-formula food (same brand as the shelter to start): USD 20–50
• Food and water bowls, ideally shallow ceramic or stainless: USD 10–25
• Scratching post or pad — non-negotiable for saving your furniture: USD 15–40
• Carrier for vet trips (hard-sided opens from the top): USD 20–45
• A few safe toys (wand toys, not loose string): USD 10–25

You can skip most of the boutique gear on day one, but a scratching post and a proper carrier aren't optional — a kitten that never learns a post will pick your sofa, and a loose kitten in the car is dangerous. Budget separately for that first vet visit, which with the exam, FeLV/FIV test, first vaccines, and deworming commonly runs about USD 100–300. Across the whole first year, most owners spend somewhere in the USD 1,200–2,300 range once spay/neuter, the full vaccine series, and supplies are counted in.

Red-flag signs to call a vet in week one

Kittens are small enough that problems escalate fast, so a few symptoms are worth a same-day call rather than a wait-and-see. Not eating for more than about a day, unusual lethargy or hiding beyond the normal settling-in, repeated vomiting or diarrhea, straining in the litter box, labored or open-mouthed breathing, and pale gums all warrant prompt attention — a kitten can dehydrate or drop its blood sugar dangerously in hours, not days. Sneezing, runny eyes, and congestion are extremely common in kittens from shelters (an upper respiratory infection) and usually aren't an emergency on their own, but check in with your vet if the kitten stops eating, runs a fever, or the eyes seal shut. When you're unsure, calling is always the cheaper mistake.

Track the first weeks with PetCare AI

The first month has more moving parts than people expect — vaccine dates three to four weeks apart, a deworming schedule, the FeLV/FIV retest, feeding amounts, and a spay/neuter date to book down the line. Log it all in PetCare AI's care calendar and get reminders so nothing slips. Ask the AI vet assistant things like "My 9-week kitten sneezes and has watery eyes but is still eating and playing — do I need the vet today?" to think through next steps, and use the in-app finder to locate a nearby clinic. It doesn't replace your veterinarian, who tailors the vaccine and deworming plan to your kitten — it just helps you show up prepared.
