Before Your Cat Walks Through the Door
The week starts before your cat arrives. Setting up a dedicated safe room — a single, quiet space like a spare bedroom or bathroom — is one of the most effective things you can do. Stock it with a litter box, food and water bowls placed well away from the litter, a hiding spot (a box with a blanket works fine), and a few toys.
Use the same food your cat was eating before adoption if possible. Switching food suddenly can upset their stomach on top of the stress of moving. Ask the shelter or breeder what they were feeding and continue with that for at least the first week.
Safe room
A single, contained space used to introduce a new cat to the home gradually. It limits how much unfamiliar territory the cat has to process at once, which reduces stress.
Stress behaviours
Actions cats display when anxious or overwhelmed, including hiding, refusing food, excessive grooming, or freezing in place. These are normal short-term responses to change.
Territory
The space a cat considers its own and feels safe within. Cats explore and claim territory gradually, which is why slow introductions to new rooms work better than immediate full-house access.
Scent marking
The way cats use smell to understand and claim their environment. Rubbing their face on objects, furniture, or you deposits scent that communicates familiarity and ownership.
Elimination
A clinical term for a cat urinating or defecating. Vets use this word when discussing litter box habits. Monitoring elimination in the first week is an important health indicator.
If you have other pets, keep them fully separated during this period. Introductions should happen gradually and never on the first day. The goal right now is simple: your cat needs to learn that this space is safe before anything else happens.
Days 1–2: Expect Hiding, Not Bonding
Most new cats spend the first day — sometimes the first two days — hiding. Under the bed, behind furniture, inside a carrier they were brought home in. This is not rejection. It is a completely normal stress response to an unfamiliar environment with unfamiliar smells.
The Quiet Presence Technique
Sit on the floor in your cat's safe room and read a book or work quietly without directing attention at them. This low-key approach lets your cat observe and assess you safely. Many cats will gradually move closer over several sessions — on their own terms, which is exactly what you want.
Resist the urge to coax them out or carry them around the house. Sit quietly in the room, speak softly, and let your cat observe you from wherever they feel safe. Place a worn t-shirt near their hiding spot; your scent helps them begin to associate you with calm rather than threat.
Check that food, water, and the litter box are accessible from where they're hiding — they shouldn't have to cross open, exposed space to reach them. Monitor whether your cat is eating or using the litter box, but avoid hovering. Short, calm visits are better than long, watchful ones.
Understanding why cats behave this way can make the waiting easier. Our article on decoding everyday feline behaviours explains the instincts behind hiding, slow blinking, and other common signals.
Days 3–5: Cautious Exploration Begins
By day three, most cats start venturing out — usually when the house is quieter, often at dawn or dusk. You may notice them sniffing around the edges of the room, watching you more openly, or approaching their food bowl while you're present rather than waiting for you to leave.
This is the window to begin very gentle interaction. Extend a slow hand near (not toward) them and let your cat sniff on their terms. If they rub against your hand or push their head into it, that's a strong positive sign. If they back away, pause and try again later.
Keep the litter box clean — once or twice daily during this period. A dirty box is one of the most common reasons cats begin eliminating elsewhere. Our guide on litter box setup and maintenance covers placement and cleaning in detail if you want more guidance.
Don't Skip the Litter Box Check
It's easy to forget to monitor litter box use when your cat is hiding and you're giving them space. Urinary blockages are a medical emergency in cats, particularly males, and can develop quickly. If you haven't seen any litter box use within 24 hours, call your vet rather than waiting to see what happens.
If your cat is hissing, swatting, or refusing all interaction by day five, that's worth noting — but not panicking about. Some cats, particularly those with limited human contact before adoption, take longer. Stay consistent and patient.
Days 6–7: Building the Routine
By the end of the first week, a routine is your most powerful tool. Feed at the same times each day. Clean the litter box on a consistent schedule. Spend calm, predictable time in the room without demanding anything from your cat.
You can begin expanding your cat's territory now if they're showing confident, relaxed behaviour — eating well, using the litter box reliably, and approaching you without obvious stress. Open the safe room door and let them explore the next space on their own schedule. Don't force it.
Avoid the common first-time mistake of treating early independence as a problem to fix. Cats that seem aloof in week one often become deeply affectionate once they feel fully secure. The contrast with dogs — who tend to bond quickly and visibly — can be jarring. If you're curious about how the first week looks with a dog instead, see our article on what to expect in week one with a new dog.
When to Call the Vet
Schedule a first vet visit within the first week if you haven't already. Even if your cat appears healthy, a baseline examination helps establish their records and catch anything missed at the shelter or by the previous owner. Our article on preparing for your first vet visit walks you through exactly what to bring and what questions to raise.
Contact your vet sooner — don't wait for the scheduled appointment — if you notice any of the following:
- No food or water intake for 48 hours
- No litter box use in 24 hours, or straining to urinate
- Sneezing, discharge from eyes or nose, or laboured breathing
- Visible wounds, limping, or signs of pain
- Extreme lethargy that doesn't improve after the first day
