Starter Supply Checklist for a Newly Adopted Cat in North York: First 72 Hours, First Month and What to Buy Twice

A newly adopted cat does not need forty products. It needs about ten, in the right order, with two or three of them duplicated so you're never scrambling at 11 PM. The first 72 hours are about safety, litter, hydration and a food the cat already recognizes; the first month is about building a diet and enrichment routine that sticks. If you're stocking up before pickup day, start with a small-format bag or a variety pack from our cat food and supplies collection rather than a 7 kg bag of something your cat may refuse.

Below is the full list first, then the reasoning, portions and measurements behind each pick. Everything here is sold as food, litter, gear or accessories — we're a supply store, not a shelter, so pair this checklist with an adoption through a licensed rescue or humane society.

1. A second litter box (the n+1 rule)
2. Unscented clumping litter plus an odour-control additive
3. Two sets of shallow stainless or ceramic bowls
4. Wet food for the first 72 hours
5. Dry, air-dried or freeze-dried food for week two onward
6. A scratching post plus one vertical perch
7. One wand toy and three solo-play toys
8. A hard-sided carrier
9. A breakaway collar and ID tag
10. A grooming kit and a transition probiotic

How we picked

Every item on this list had to meet three tests: it solves a problem that shows up in the first 30 days, it's available in a small or trial size so you're not committed to 10 lbs of the wrong thing, and it's made by a brand we stock and can explain. We weighted litter and food heaviest because those two categories drive the majority of returns-and-exchanges conversations we have with new adopters. Enrichment made the cut too — under-stimulated indoor cats develop habits that cost far more to fix later.

1. A second litter box (the n+1 rule)

The standard guidance from feline behaviour specialists and the ASPCA is one litter box per cat plus one spare — so a single adopted cat needs two boxes, placed in separate rooms. Box length should be roughly 1.5 times your cat's body length nose to tail base, which for most adult cats means an interior length of 24 inches or more.

Buy twice: yes, this is the number one duplicate. In a Toronto condo or a basement apartment near Finch West, the second box usually goes on a different floor or at the opposite end of the unit so the cat never has to cross a loud appliance to reach one. Uncovered boxes get accepted faster by cats coming out of a shelter environment; you can add a hood later. Keep litter depth at 5–7 cm (about 2–3 inches) — deeper than that and most cats start digging litter onto the floor.

2. Unscented clumping litter plus an odour-control additive

Start with the same litter texture the cat used at the shelter, then transition over 7–10 days by mixing 25% new litter at a time. Fragrance is the most common rejection trigger we hear about, so unscented is the safe default for the first month.

Here's how two of the plant-based options in our cat litter collection compare:

An additive such as OdourLock or Arm & Hammer deodorizer stretches the time between full box changes, but it doesn't replace scooping twice a day. Corn and walnut litters need dry storage — GTA basements hit high humidity in July and August, so keep the bag sealed and off the concrete floor.

3. Two sets of shallow stainless or ceramic bowls

Cats drink roughly 50 ml of water per kilogram of body weight per day from all sources, so a 4.5 kg cat needs about 225 ml daily — much of which should come from food. Use shallow, wide bowls (13–15 cm across, under 5 cm deep) to avoid whisker contact with the sides, which some cats genuinely dislike.

Buy twice: yes. One set in the wash, one set in service, and a separate water bowl placed at least 1–2 metres away from the food. Stainless and ceramic resist the biofilm that builds up in scratched plastic. Add a third standalone water station if your home has more than one floor.

4. Wet food for the first 72 hours

For the first three days, feed wet food in small, frequent portions — four meals of 40–60 g each rather than two large servings. Wet food runs 70–80% moisture, which protects hydration in a cat that's stressed and may not be drinking normally yet.

A standard 5.5 oz (156 g) can delivers roughly 165–200 kcal depending on the recipe, and a typical 4.5 kg indoor adult cat needs about 180–220 kcal per day in total. Pâté textures from brands like Weruva, Tiki Cat, Inaba and Snappy Tom are easy to warm slightly, which lifts aroma for a cat that's not eating. Our team recommends buying a mixed case of three or four textures from the wet cat food selection instead of a single flavour — in our store we see first-week refusals resolve almost entirely once owners offer a shred or flaked texture alongside pâté.

5. Dry, air-dried or freeze-dried food for week two onward

Once the cat is eating reliably, build the long-term diet. AAFCO reviews its Official Publication nutrient profiles annually, and the 2026 edition holds the adult-maintenance minimum at 26% crude protein on a dry-matter basis, with 30% for growth and reproduction. Taurine minimums sit at 0.10% dry matter for extruded dry food and 0.20% for canned.

Check the guaranteed analysis panel for protein content, fat content and fiber content, and confirm the AAFCO life-stage formulation statement on the back of the bag. Dry formulas from Fromm, Go! Solutions, Acana and Orijen in our dry cat food range typically run 350–450 kcal per cup, so a cat eating 200 kcal a day needs roughly half a cup. Freeze-dried and air-dried options from Stella & Chewy's, Instinct Raw, Primal and Caru are calorie-dense — often 120–160 kcal per ounce — and work well as a topper at 10–20% of daily intake. Transition over 7–10 days: 25% new food for days 1–3, 50% for days 4–6, 75% for days 7–9.

6. A scratching post plus one vertical perch

A scratching post needs to be at least 80 cm tall so a cat can fully extend, and heavy enough not to wobble — wobble is the main reason posts get ignored. Sisal rope and corrugated cardboard are the two surfaces most cats choose on their own.

Place the post beside the spot the cat already sleeps in, not in a back corner. Vertical space matters just as much: a window perch or a two-tier tree gives an anxious newcomer somewhere to observe from, which shortens the hiding phase noticeably. Pet owners tell us the post-plus-perch combination cuts couch scratching faster than any deterrent spray.

7. One wand toy and three solo-play toys

Plan on two interactive play sessions of 10–15 minutes per day, ideally before meals to mirror the hunt-eat-groom-sleep cycle. One wand toy covers the interactive half; three small solo toys cover the hours you're at work.

Buy twice: yes for wand toys — feathers and strings wear out, and a mid-play failure ends the session. Rotate solo toys weekly so four toys feel like twelve. Our cat toy collection includes kicker toys, puzzle feeders and crinkle balls from brands like Kong, JW Pet, ZippyPaws and Smart Pet Love. Store string and wand toys out of reach between sessions — the American Veterinary Medical Association flags linear foreign bodies as a genuine emergency risk in cats.

8. A hard-sided carrier

Buy the carrier before adoption day, not after. A top-loading hard-sided carrier with a removable lid lets you lower a resistant cat in rather than pushing them through a front door, and it doubles as an exam table at the vet clinic. Size it so the cat can stand and turn around — roughly 1.5 times their length.

Leave the carrier out as furniture with a blanket inside from week one. Petmate models with twist-lock hardware handle TTC and car trips without the shell flexing. A cat that associates the carrier with naps rather than vet visits is a dramatically easier patient.

9. A breakaway collar and ID tag

Indoor cats escape — most often through a balcony door or during a move. A breakaway collar with a flat ID tag is the fastest identification layer, and it should fit with two fingers of clearance under the strap. Microchipping stays the permanent backup and is a conversation for your veterinarian.

Check collar fit every two weeks on cats under 12 months, since kittens outgrow a collar in as little as 30 days during the growth phase. Harnesses are optional and only worth it if you plan supervised balcony or patio time.

10. A grooming kit and a transition probiotic

A starter grooming kit is three items: a slicker or rubber curry brush, nail clippers, and grooming wipes. Most adult cats need a nail trim every 2–3 weeks, and long-haired cats need brushing 3–4 times weekly to prevent mats behind the ears and in the armpits.

Stress-related loose stool is common in the first week of a new home. Probiotics and prebiotics, plus omega-3 and omega-6 from fish oil for coat condition, are the two supplement categories we're asked about most. Our nutrition experts suggest starting a probiotic only after the cat is eating consistently, and dosing by package weight guidance — typically 1 g per day for a cat under 5 kg. Browse grooming tools and TropiClean products in our cat grooming section, and supplements in the cat health and wellness range. Any diarrhea lasting more than 48 hours, or any refusal to eat for over 24 hours, warrants a call to your veterinarian rather than a supplement.

Our store at 1111A Finch Ave W, Unit 2, North York, ON M3J 2P7 is open 7 AM to 11 PM daily, with local delivery available via DoorDash and other apps. Bring your adoption paperwork and we'll match the shelter's food so your cat's first meal at home tastes familiar.

New cat supply questions, answered

What should I buy for a new cat before bringing them home?

Buy two litter boxes, one bag of unscented clumping litter, two sets of shallow bowls, a case of wet food matching the shelter's diet, a hard-sided carrier, a scratching post and one wand toy. That seven-item core covers the first 72 hours. Add dry or freeze-dried food, a collar and grooming tools in week two.

How much food does a newly adopted adult cat need per day?

A typical 4.5 kg (10 lb) indoor adult cat needs about 180–220 kcal daily, split into three or four meals during the settling-in period. That's roughly one and a quarter 5.5 oz cans, or half a cup of a 400 kcal-per-cup dry formula. Confirm the exact target with your veterinarian based on body condition score.

Which new cat supplies are worth buying twice?

Five: litter boxes (n+1 rule), bowl sets, wand toys, scoops, and water stations in multi-level homes. Duplicating these costs little and removes the two most common friction points — a dirty box with no backup, and a broken toy mid-play. Everything else on the checklist works fine as a single purchase.

How long does it take an adopted cat to settle in?

Most cats follow a rough 3-3-3 pattern: three days of hiding, three weeks of learning the routine, three months of fully relaxing. Confine the cat to one room with food, water, litter and a hiding spot for the first few days, then expand access gradually. Rushing the expansion is the single most common setback we hear about.

Key takeaway: Ten items cover a new cat's first month, and only five of them are worth duplicating — litter boxes, bowls, wand toys, scoops and water stations. Match the shelter's food for the first 72 hours, then transition to an AAFCO-complete adult formula over 7–10 days while keeping daily intake near 180–220 kcal for an average indoor cat.
