Adopting a cat in Canada: the first 30 days, done right
Noisy Lion donates litter to shelters and rescues, so I hear the same story from both sides of an adoption. The shelter says: “She was confident here.” The adopter says: “He has been under the bed for five days.” Both are true. The first month is not about whether you got a good cat — you did — it is about whether your home gives that cat a predictable runway to land on.
Here is the 30-day plan I share when shelters ask what to tell new adopters — including the one thing almost everyone gets wrong with the litter box.

The short answer: 3-3-3
Shelters use a rule of thumb worth memorizing: 3 days to decompress, 3 weeks to learn your routine, 3 months to fully feel at home. Your job in month one: keep the world small, keep it predictable — and do not change their litter yet.
The first 30 days, step by step
Before day one: build the base camp
One quiet room — a bedroom or office, not the open-concept living room. Litter box in a low-traffic corner (not beside the noisy furnace or washer), food and water across the room from the box, a hiding spot they are allowed to use (a box on its side works), and a blanket or towel that came with them from the shelter if possible — familiar smell is gold.
Ask the shelter one question: “What litter are you using?”
The most skipped question at pickup. Whatever the answer — often a basic clay or paper pellet — start with the same thing. A new home is enough change; a new bathroom floor on top of it is how accidents start. Buy a small bag of the shelter litter and plan your upgrade for week three, not day one.
Days 1–3: decompress — do not perform friendship
Keep them in the base camp room. Sit on the floor, read out loud, let them come to you — or not. Hiding, small appetite and no play are normal for 72 hours. What matters: they eat something, they drink, and they use the box. Check the box quietly twice a day; using it is your best signal things are on track.
Week 1: build the clock
Cats settle on schedules before they settle on people. Feed at the same times, scoop at the same times, play (wand toy, five minutes) at the same times. Keep the box in the same spot — moving it now resets trust. Book the first vet visit for the end of week one or two unless the shelter flagged something urgent.
Weeks 2–3: open the doors
Confident eating, relaxed body, greeting you at the door of the room — open up more territory one zone at a time. Add the second litter box now if your home is multi-floor or you have more than one cat (the rule is one box per cat, plus one). Same litter in both boxes, still.
Week 3–4: now upgrade the litter — gradually
Once habits are solid, switch to your long-term litter with the 10-day mixing method — 25% new, then 50%, then 75%, watching the box at each step. For a fresh start we recommend unscented or lightly scented, low-dust and undyed: it is the least likely to be rejected, and small stressed lungs deserve clean air. That is the exact profile our litter is built to — 99.9% dust-free, CTI lab-verified, published.
Day 30: lock in the rhythm
By now you know their appetite, their box habits and their play style — the three things a vet will ask about. Put the rebuy on rails (a litter subscription means one less thing to remember), keep the schedule, and let month two and three do their slow magic.

Straight talk
Adoption month is chaotic and the internet will sell you fifty gadgets for it. Most are optional. The things that are not: a quiet room, a boring schedule, one vet visit, and a litter box your cat trusts. Litter is one of the few variables you can fully control for a few dollars — control it, and give every other variable time.
My newly adopted cat is not using the litter box. What do I check first?
In order: box location too exposed or too far, litter changed too soon after adoption, box too tall for a senior or kitten, box dirty, or stress from too much territory too fast. Shrink the world back to one room and restart. If it persists more than a few days — or you see straining — call your vet.
When can I switch litters after adopting?
Around week three, once eating and box habits are stable — and gradually, over 7–10 days of mixing. Never cold-turkey a litter change in the first month.
What litter do shelters use?
Usually whatever is donated or cheapest — often basic clay or paper pellets. That is fine for the transition window. It is also why we donate litter to shelters: cleaner air for cats waiting on their own adoption day. See our Community Impact page.
I adopted a senior cat — anything different?
Lower box walls (or a low entry cut), the box on the floor they live on with no stairs required, and extra patience on the 3-3-3 timeline. Seniors often settle more slowly but more deeply.
What should I buy before day one?
Box, litter (same as shelter first), scoop, food and water dishes, a wand toy, a hiding spot. Our Complete Litter Set — pan, scoop and up to 12 weeks of litter — covers the box side in one purchase for when you make the switch.
Set up the box side in one go
The Complete Litter Set — pan, scoop and up to 12 weeks of low-dust, lab-verified litter from $38.99 — or start with a 2.4 kg pack for the week-three switch. First 2-pack is 100% money-back. And every order helps fund litter donations to Canadian shelters.
