The first week is not about bonding. It is about building a small, boring, predictable territory and then widening it on a schedule, because a cat that is given the whole flat on day 1 spends 3 days under a sofa and learns nothing. One room of 3 to 4 square meters, 3 zones inside it, and a 7-day table that adds space and contact minutes in fixed steps is the whole plan. Food, water, litter and hiding are measured, not improvised.
One room, 3 zones
The base room needs a hiding zone, a resource zone and a lookout zone, and they must not be the same corner. Hiding goes where the cat can watch the door from cover, not in a closed cupboard. Resources go on the wall farthest from the door, with the litter box at least 1.5 m from food and 2 m from water. The lookout is a perch 90 to 150 cm up, because height is what converts a scared cat into a cat that can observe. Close the door on day 1 and put a note on it.
Two things get removed before the cat arrives: anything breakable below 60 cm, and any gap wider than 5 cm behind furniture, since a cat that wedges itself behind a wardrobe at 23:00 costs a furniture move and 2 hours of stress for both of you.
Sizes that matter, in centimeters
| Zone | Minimum size | How many | Distance rule | Height |
|---|---|---|---|---|
| Litter box | 1.5 times body length, so 65-70 cm | 2 for 1 cat | 1.5 m from food | rim 15-20 cm |
| Hiding box | 30 x 30 x 30 cm | 3 | 1 within 2 m of the bed | door hole 15 cm |
| Food station | bowl 12-15 cm wide | 2 bowls | 2 m from water | floor, not raised |
| Scratching post | base 40 x 40 cm | 2 | 1 next to the bed | 60-90 cm sisal |
| Lookout perch | platform 40 x 30 cm | 1 | facing the door | 90-150 cm |
Two bowls, 2 m apart
Water next to food is the most common first-week mistake: many cats will not drink beside a food bowl, and a cat that arrives dehydrated and then drinks 40 percent less for 4 days is a cat that ends up at the vet on day 5. Put water 2 m away, in 2 places, in wide shallow bowls filled to 3 cm, and change it twice a day. A cat needs roughly 40 to 60 mL per kg per day; a 4 kg cat that eats only dry food needs about 200 to 240 mL, and most of it has to come from the bowl.
The 7-day table
| Day | Space open (square meters) | Contact per session (minutes) | Sessions | Goal |
|---|---|---|---|---|
| 1 | 3-4 | 0 | 0 | Eat, drink, use the box once |
| 2 | 3-4 | 5 | 1 | Sit 1.5 m away and talk |
| 3 | 4-6 | 5 | 2 | Take 2-3 treats from the hand |
| 4 | 6-8 | 10 | 2 | Brush for 3 minutes |
| 5 | 8-10 | 10 | 2 | Wand toy, 5 minutes of chase |
| 6 | whole home, doors to hazards closed | 15 | 2 | Explore 1 new room, answer to name |
| 7 | whole home | 15 | 2 | Book the vet visit for day 7-10 |
Day 1 to 3: no holding, no bath, no guests
Day 1 contact is zero minutes of handling and 2 or 3 looks through a cracked door. A kitten under 6 months runs the same table faster (kitten first week). Put the carrier on the floor, open it, and leave the room; a cat that walks out on its own in 10 minutes is ahead of schedule, and a cat that stays in for 4 hours is normal. Feed the food it was already eating, in 4 to 6 small portions a day, starting at about 25 percent of the expected daily amount and reaching 100 percent by day 5 to 7. Do not bathe a cat in the first 48 hours, and do not invite anyone over before day 7, because every new person resets the count.
Day 3 is the first hand contact: 2 or 3 pieces of freeze-dried treat, offered at floor level, then walk away. Total 5 minutes. If the cat hisses, the session ends and tomorrow repeats the same step; the schedule is a ceiling, not a quota.
Day 4 to 7: brush, play, then open the door
Day 4 adds a soft brush for 3 minutes on the cheeks and shoulders only, which most cats accept long before they accept a hand on the back. Day 5 adds a wand toy and 5 minutes of chasing, ending with a small meal so the hunt has a finish. Day 6 opens 1 more room with hazards closed: washing machine, dryer, balcony door, and any gap behind the fridge. Day 7 is the whole flat with the base room door left open, so the cat can retreat, and a vet appointment booked for day 7 to 10 rather than day 30. The graded widening is the same logic as a 6-week rehab plan: add 1 variable at a time.
Daily numbers to write down
Five numbers a day for 7 days: grams eaten, milliliters drunk, clumps in the litter box, stools, and hours spent hiding. A cat that eats 40 g on day 1, 55 g on day 3 and 65 g by day 7 is settling; a flat line at 25 g is not. Urine should appear 2 to 4 times a day, stool once every 1 to 2 days. Weigh on a kitchen scale every 3 days: an adult cat should hold weight within 2 percent, and a kitten should gain 10 to 15 g a day.
The 24-hour red flags
No food for 24 hours, no urine for 24 hours, or no stool for 48 hours means a visit, not a wait. A male cat that crouches in the box and produces nothing for 12 hours is an emergency, because a blocked urethra can become fatal in 24 to 36 hours. Also act on a temperature under 37.5 or over 39.5 degrees Celsius, breathing over 40 breaths a minute at rest, hiding for 48 hours without coming out to eat, or sneezing with eye and nose discharge, which is often the start of an upper respiratory infection that shows up 2 to 10 days after arrival.
Five things to set up before the cat arrives
- Close 1 room of 3 to 4 square meters and put 3 hiding spots inside it.
- Place 2 litter boxes 1.5 m from food, each 65 to 70 cm long.
- Put water 2 m from the food in wide bowls filled to 3 cm, and budget the setup before you shop (cost tool).
- Raise 1 perch to 90-150 cm facing the door.
- Write the 7-day table on paper and stick it on the door.
Frequently asked
Should a new cat have the whole house on day one?
No. Start with 1 room of 3 to 4 square meters that contains a hiding spot, a feeding and litter zone, and a perch 90 to 150 cm up. A cat given the whole flat on day 1 usually hides under furniture for 3 days and eats less. Open 1 new room on day 6 and the whole home on day 7, leaving the base room door open so the cat can always retreat.
How much should a newly adopted cat eat in the first week?
Start with about 25 percent of the expected daily amount, split into 4 to 6 small portions of the food the cat was already eating, and reach 100 percent by day 5 to 7. Write down the grams each day: 40 g on day 1 rising to 65 g by day 7 is normal settling, while a flat 25 g is a reason to call. Any cat that eats nothing for 24 hours needs a visit.
When should the first vet visit happen?
Book it for day 7 to 10, not day 30. By then the cat has eaten and used the litter box at home, so the visit gives useful baseline numbers, and upper respiratory infections that appear 2 to 10 days after arrival are caught early. Bring the 7-day log of grams eaten, milliliters drunk and litter box counts, since those numbers change the exam.
