What to set up first, and what can wait

The seven-day path is deliberately ordered. If you only have one evening before the cat arrives, the five items below cover almost everything that has to be right on day one; everything else can be added once your cat is eating, using the tray and sleeping somewhere they chose themselves.

PriorityWhat it looks like in practiceWhy it comes first
A room of their ownOne quiet room, door closed for the first days, with a hiding spot the cat can reach without passing youInternational Cat Care starts its home guidance from a cat’s need to feel in control of their surroundings — a whole new home is a lot of territory to process at once
Tray, food and water, spread apartAt least one tray — the OSU checklist sets the baseline at one per cat, cleaned daily — with water away from the foodCats asked to eat beside their toilet, or drink beside their food, often quietly reduce one of the two
Something to scratchA sturdy post or pad placed where the cat already stretches when they wakeScratching is marking and claw maintenance, not misbehaviour; punishing it damages the relationship
One perch and one bolt-holeAny raised view — a window ledge, a shelf, a cat tree — plus a covered box or a carrier with the door removedHeight and cover let a cat choose distance without leaving the room
A predictable routineSame feeding times, quiet play at a fixed point in the day, no visitors in the first weekPredictability is the main variable an owner actually controls in the first fortnight

What genuinely can wait: harness training, puzzle feeders, a second cat, grooming appointments, and any product you have not yet seen your cat use. Nothing on that list is broken by arriving in week three instead of week one.

If the first week goes badly

Hiding, hissing and eating cautiously for a day or two are normal in a new home; the hiding after adoption guide covers the ordinary version. The version that needs a call is different: not eating for more than a day, straining to urinate, repeated vomiting, or breathing faster than about 35 breaths a minute. Cornell Feline Health Center lists rapid breathing above 35 breaths per minute among the signs to have checked rather than watched, and straining to urinate is an emergency at any hour. The symptom checklist sorts those signs by how fast to move.
