A kitten's first 72 hours at home set the tone for the next 3 weeks. The plan that works is 1 small room at 24–26 °C, 3 water stations, 4 small meals a day and a written intake log — not a lap and a house tour. Day 1 is for watching, days 2–3 for short contact, and the first bath or visitor waits until day 7.

Prep the room before the carrier opens

Pick a room of 4–6 m². Under 4 m² there is no distance between litter and food; over 8 m² an 8-week-old kitten can hide where you cannot check it. Tape loose cables, block the gap behind the washer with rolled towels, and move plants out of reach. Hold 24–26 °C and 40–60% humidity for the first 5 days: a kitten under 1 kg loses heat through its belly, so bedding belongs on the floor, never on a shelf. A 40 × 60 cm fleece bed plus a 30 × 40 cm box with a 12 cm doorway gives a hiding place you can still see into.

Two litter boxes go in for 1 kitten under 12 weeks, each at least 1.5 times the kitten's body length, 8–10 cm of unscented clumping litter, and both placed away from the food bowls. Keep the carrier in the room with the door removed so it reads as furniture by day 2.

Day 1: no holding, 3 quiet checks

Do not pick the kitten up for the first 12 hours beyond setting it down and weighing it once. After that, 2–3 checks of 30 seconds each are enough: eyes, rear end, breathing. Weigh at the same time daily on a kitchen scale accurate to 5 g. An 8-week-old kitten usually sits at 0.8–1.0 kg and gains 50–100 g a week; a 5% drop in 24 hours, or 2 flat days in a row, means a vet call that same day. Sitting still and hiding are normal on day 1. A kitten that hides but eats overnight is doing better than one that plays hard and skips 2 meals.

Water in 3 places, food in 2

Set 3 water bowls at least 1.5 m apart, one within 1 m of the bed. Ceramic bowls 8–10 cm wide with 2–3 cm of water are easier to judge than a tall fountain, and 3 stations mean a shy kitten does not have to cross the room to drink. Food goes in 2 spots away from the litter, 4 meals a day at 8–12 weeks, about 170–200 kcal a day for a 1 kg kitten in 40–50 kcal portions. Offer 60–70 g of wet food or 25–30 g of dry per day as a starting point and let the bowl tell you the rest. Keep the shelter's or breeder's food for 7 days, then switch over 7–10 days in 25% steps.

The 72-hour intake sheet

One sheet on the door, 5 columns, filled in at every check. The numbers that matter are offered versus eaten, urine, stool and minutes of contact.

Under 50% of the target for 2 windows in a row is the trigger for a same-day call, not a wait-and-see day.

Contact minutes by week and weight

  • 8–10 weeks, 0.8–1.0 kg: 2 sessions × 2 minutes, hands only, no lifting.
  • 10–12 weeks, 1.0–1.4 kg: 3 sessions × 3 minutes, add a 5-second chin scratch.
  • 12–16 weeks, 1.4–1.9 kg: 3 sessions × 5 minutes, start a 60-second brushing pass.
  • 4–6 months, 1.9–3.0 kg: 2 sessions × 10 minutes, add nail handling on 1 paw.
  • 6 months and up: 10 minutes of daily grooming plus 2 play blocks of 10 minutes.

What sends you to the vet in the first 3 days

Call the same day for no food for 12 hours (8 hours under 12 weeks), no urine for 12 hours, no stool for 48 hours, a rectal temperature under 37.5 °C or over 39.5 °C, resting breaths over 40 a minute, weight down 5% in 24 hours, or 2 bouts of vomiting within 6 hours. Bring the intake sheet: 3 days of numbers answers half the triage questions before the exam starts.

Days 4–7: one room at a time

Open 1 more room every 2 days, and let the kitten choose the door. Add 3 play sessions of 10 minutes with a wand toy kept 30 cm from the face, and put away string, hair ties and anything under 3 cm across — see toy safety in the first months before the toy box grows. At day 7–10, do the first 60-second handling pass: 2 paws, ears, mouth. A kitten that tolerates 1 paw per day at 10 weeks will still tolerate it at 10 months.

Book the first exam for day 3–5

Book the vet visit for day 3 to 5, not week 2. Bring 3 things: the intake sheet, a stool sample under 24 hours old in a clean 50 ml pot, and the vaccine card from the shelter. Expect a weight in grams, a flea-comb pass over 5 areas (neck, armpits, groin, tail base, belly), an ear swab and a plan for the 8–9 week booster. A kitten at 1.2 kg in week 10 is on track; 0.7 kg at the same age pushes the vaccine schedule back 2 to 3 weeks. Write the clinic weight next to your 3 home readings — a 20% gap between the two scales means one of them is wrong. Still choosing a kitten? The 6-question breed quiz narrows the size and coat range before you buy 4 different brushes.

Night 3 checklist

  • Room at 24–26 °C, no draft under the door, bed on the floor.
  • 3 water bowls filled, 2 food spots cleaned, 2 litter boxes scooped twice a day.
  • Weight logged for 3 days, trend flat or up.
  • At least 1 stool and 3 urine clumps in 24 hours.
  • Carrier open in the room, door off, blanket inside.

If all 5 lines are true, extend the room on day 4 and keep the sheet running for 7 more days. If 2 or more are false, hold the kitten in the small room and book a vet visit within 24 hours.

Frequently asked

Can I let the kitten sleep in my bed on the first night?

Not on night 1. A kitten under 1.2 kg can be rolled onto or trapped between the mattress and the wall, and the first night is when you most need an undisturbed weight and intake baseline. Put the bed next to your bed or sleep in the kitten room for 2 to 3 nights, then allow bed access after week 2 if the weight curve is rising 50 to 100 g a week.

How long should the kitten stay in one room?

Plan on 5 to 7 days for a kitten of 8 to 12 weeks, then open 1 new room every 2 days. Extend the stay if the kitten is still hiding at every check, eating under 50% of target, or has lost 5% of body weight in 24 hours. A slower ramp costs you 1 week; a fast one can cost you a litter box habit that takes 3 months to fix.

What if the kitten cries all night?

Expect 2 to 3 nights of calling at 8 to 10 weeks, in bursts of 10 to 20 minutes. Answer with a low voice from outside the door, no lights and no picking up, then leave for 10 minutes. Feed the last meal within 1 hour of your bedtime, add a 40 °C heat pad under half the bed, and keep the carrier open so the kitten has a 30 cm box to retreat into.
