You do not need to buy half the pet store before your cat comes home. You need the few supplies that keep your cat safe, fed, contained, and able to use the bathroom while they figure out where they are. This checklist covers what to buy now, what to set up first, and what can wait until you know your cat better.

Key takeaways

  1. 1Your cat needs fewer things than stores suggest, and a carrier, safe room, litter setup, food, water, scratching surface, and basic ID cover the first days.
  2. 2Set up one quiet room before pickup so your new cat can hide, eat, and use the litter box without the whole home feeling overwhelming.
  3. 3Use the food and litter your cat already knows at first, then make changes slowly after your cat is eating and using the box normally.
  4. 4Cat proofing matters as much as shopping because plants, cords, medicines, string, open windows, and recliners can hurt a curious new cat.
  5. 5Most extras can wait until you learn your cat's size, habits, confidence level, and favorite ways to play.

What do you need before bringing a cat home?

The day one list is shorter than most new adopters think. Before pickup, you need a secure carrier, a litter box with litter, the food your cat already knows, food and water bowls, one quiet room, a scratcher, a hiding place, a few simple toys, ID, and basic cleaning supplies.

The goal is not to create a perfect cat palace. The goal is to help your cat get from the shelter or rescue to your home safely, then give them a small place where they can eat, hide, use the box, and sleep without pressure. If you are still looking for the right match, you can find shelters and rescues near you before you shop.

ASPCA general cat care guidance supports the basics most cats need: food, fresh water, a litter box, safe shelter, scratching options, and routine care. You can also use Paaw's new pet checklist if you are setting up for more than one kind of pet.

For the first few days, think in zones. Your cat needs a bathroom zone, a food and water zone, a sleeping or hiding zone, and a scratch or play zone. These can all fit in one bedroom, office, or quiet bathroom if the room is safe and not too busy.

Buy small amounts at first when you can. Cats have strong preferences about litter texture, food flavor, bed shape, and scratching material. A smaller starter setup lets you adjust without wasting money.

How do you set up a safe room for a new cat?

One quiet room helps most adopted cats feel safer than having the whole home open on day one. A new cat does not know your smells, sounds, floor plan, or routines yet. Too much space can turn into panic, hiding inside furniture, or a litter box accident in a far corner.

Pick a room with a door that closes. A spare bedroom, office, or low traffic bathroom can work. Avoid laundry rooms if machines run often, and avoid rooms with lots of hiding spots you cannot reach, like an unfinished basement packed with storage.

Set the room up before you leave for pickup. Put the litter box on one side of the room, away from food and water. Place food and water several feet apart if you have space, since many cats prefer water that is not right next to their meal. Add a soft towel or blanket, a cardboard box or covered bed for hiding, and a scratcher near the area where the cat may rest.

Do not block every hiding place. Hiding is a normal coping tool. The safer version is to give your cat an approved hideout, such as a box on its side with a towel inside, instead of letting them disappear behind a heavy dresser.

Keep the room boring in a good way. Close windows, tuck cords away, remove plants, pick up hair ties and string, and check that vents and closet doors are secure. If you are bringing home a young cat, read about bringing a kitten home, since kittens often need extra proofing and supervision.

The Humane Society recommends giving new cats time and a small starting space as they adjust to a home, and their new cat adjustment advice matches what many shelters tell adopters: let the cat choose when to approach. Sit on the floor, speak softly, and avoid pulling the cat from the carrier or hiding spot.

Some cats walk out in ten minutes. Others hide for a day or two and only explore at night. Both can be normal if the cat is eating, drinking, using the litter box, and not showing signs of illness. For a broader timeline, see how long it takes an adopted cat to adjust.

What litter box setup does a new cat need?

A good litter setup is simple, easy to find, and easy for the cat to enter. Most adult cats do best with a box that is at least one and a half times the length of the cat from nose to base of tail. If your cat is large, skip the tiny starter pan and choose a roomy box from the beginning.

Uncovered boxes are often the safest first choice. Covered boxes can trap odor, feel cramped, and make some cats feel cornered. If the cat already used a covered box at the shelter, you can try one, but do not make the first week harder by changing too many things at once.

Ask the shelter or rescue what litter the cat has been using. Buy that type first if you can. If your cat has been using unscented clumping clay, start there. If they used paper pellets, start there. You can switch later by mixing a small amount of the new litter into the old litter over several days.

A common setup is one litter box per cat, plus one extra when possible. For one cat, two boxes are helpful but not always possible in a small apartment. If you can only manage one at first, make it easy to access, keep it very clean, and avoid placing it next to noisy appliances.

Scoop at least once a day. Many cats avoid dirty boxes, and new cats are already dealing with stress. Full litter changes depend on the litter type, the number of cats, and odor, but do not wait until the room smells bad.

Good box placement matters as much as the box itself. Put the first box in the safe room where your cat can reach it without crossing a busy hallway. Later, if you open more of the home, add or move boxes slowly so your cat is not suddenly hunting for the bathroom.

The ASPCA notes that litter box problems can be linked to box cleanliness, location, litter type, stress, or health issues. If your cat strains, cries, makes frequent trips with little urine, or cannot pee, treat it as urgent and contact a veterinarian or emergency clinic.

If you want a low dust or odor focused litter, a product box may be useful here, but the main rule still stands: start with what your cat knows if you can. Familiar texture and smell make the first week easier.

What food and water should you have ready for an adopted cat?

Ask the shelter what your cat has been eating, including the brand, flavor, wet or dry form, and meal schedule. Buy a small amount before pickup. The first week is not the time to test five new foods, even if you plan to upgrade later.

Keep meals boring at first. Offer the familiar food in the safe room, then step away. Some cats will not eat while you watch, especially on the first night. Others eat right away and then hide again.

If you need to change food, do it slowly after your cat is eating normally. A common approach is to mix a small amount of the new food with the old food, then increase the new food over about a week if stools stay normal. Go slower for cats with sensitive stomachs or a history of vomiting or diarrhea.

Food labels can be confusing, but the FDA explains pet food label basics, including product names, ingredient lists, and nutritional adequacy statements. For day one, the most practical label detail is whether the food is meant to be complete and balanced for your cat's life stage.

Fresh water should be available at all times. Use a clean bowl that is wide enough that your cat's whiskers do not press hard against the sides. Wash bowls daily, especially if you feed wet food nearby.

Many cats like wet food because it adds moisture, while dry food can be convenient. You do not need to decide your cat's forever diet before adoption day. If your cat has kidney disease, urinary issues, allergies, diabetes, dental pain, or a prescription diet, follow the shelter's instructions and book a vet visit to make a plan.

A skipped meal on the first night can happen, especially if the cat is hiding and alert. But a cat who eats nothing for 24 hours, seems weak, vomits repeatedly, has diarrhea, or refuses water needs a call to a vet. Kittens, senior cats, and cats with known medical conditions should not wait as long.

For a deeper feeding plan, read what to feed a newly adopted cat. It can help once your cat is settled enough that diet changes make sense.

What carrier, ID, and vet paperwork should be ready?

Bring a secure carrier to pickup, even if the shelter says the cat is calm. A loose cat in a car is dangerous. They can crawl under the pedals, bolt when a door opens, or wedge themselves under a seat where you cannot reach them.

Choose a carrier that closes firmly and has enough room for the cat to stand, turn around, and lie down. Hard sided carriers are easy to clean and often feel more stable. Soft carriers can work if the zippers lock or clip and the mesh is strong enough for a frightened cat.

Line the carrier with a towel or washable pad. Do not fill it with toys or bulky bedding that takes up space. If the shelter sends home a blanket that smells familiar, place it in the safe room after arrival or in the carrier if there is room.

Before adoption day, ask what paperwork you will receive. You want the adoption contract, vaccine history, deworming and flea treatment history if known, spay or neuter status, microchip number, and any medical notes. If the cat is on medication, ask for written instructions and enough medication to bridge you to a vet visit.

Book a first vet visit soon after adoption, often within the first week or two unless the shelter gives a different timeline. The visit helps confirm weight, vaccines, parasite prevention, dental health, and any follow up needs. Bring every record the shelter gave you.

Indoor cats still need ID. The first few weeks are when door dashing and hiding are most likely because your cat does not know the home yet. A breakaway collar with a visible ID tag can help a neighbor call you quickly if your cat slips out, while a microchip helps if the collar comes off.

Check the microchip registration yourself. Some chips are still registered to the shelter until you update them. Keep your phone number, email, and address current, and save the chip number with your vet records.

If you use visible ID, keep the tag simple: cat's name if you want, your phone number, and a note such as indoor cat if space allows. A product box for ID tags can fit here, but the real need is clear contact information on a safe collar.

How do you cat proof your home before adoption day?

Cat proofing is not about making your home empty. It is about removing the things most likely to hurt a curious, stressed, or bored cat before you are trying to solve a problem at midnight.

Start with plants. Many common houseplants can upset a cat's stomach, and some are much more dangerous. Lilies are a special concern because exposure can be life threatening for cats. The safest choice is to keep lilies out of any home with a cat.

If your cat chews, licks, or is exposed to any part of a lily, contact a veterinarian or pet poison control right away. Do not wait for symptoms. Bring the plant name or a photo if you can.

Use the ASPCA toxic and non-toxic plant list when you are unsure. Paaw also has guides to toxic plants for cats and dogs and common toxic plants and safer alternatives if you want a room by room check.

Put away string, yarn, ribbon, dental floss, rubber bands, hair ties, sewing thread, and small toy parts. Cats often bat these around first, then chew or swallow them. Long string like items can cause serious intestinal problems and should not be left out.

Secure cords where you can. Unplug chargers not in use, bundle loose cords, and move tempting cords behind furniture or cord covers. If your cat is a chewer, treat cords as a safety issue, not just an annoyance.

Lock up medications, cleaners, essential oils, pest products, and human foods that are unsafe for cats. Do not leave pills on a nightstand or bathroom counter. Cats can knock a bottle down, chase a pill, or step in a spill and lick their paws later.

Check windows and doors. Screens should be secure, and upper floor windows should not be left open wide just because there is a screen. Balconies are risky for new cats because stress and birds can lead to sudden jumps.

Look at furniture and appliances from a cat's point of view. Recliners, sofa beds, dryers, washers, and dresser drawers can trap or injure a hiding cat. Before you close, start, fold, or move anything, know where the cat is.

What toys, scratching posts, and climbing spots should you buy?

You do not need a basket full of toys on the first day. You need a few safe ways for your cat to scratch, chase, pounce, and climb when they are ready. Many new cats ignore toys at first because they are busy listening, smelling, and hiding.

Start with one wand toy for play with you and two or three small solo toys, such as soft balls or toy mice. Put wand toys away after use because strings can be chewed. Rotate solo toys every few days instead of dumping everything on the floor at once.

Short play sessions usually work better than long, forced ones. Try five minutes with a wand toy, then stop before your cat gets overwhelmed. If the cat watches but does not chase, that still tells you something. They may need more time.

Scratching is normal cat behavior, not bad manners. Offer at least one scratching surface in the safe room. Many cats like vertical sisal posts, but cardboard scratchers are cheap, light, and often loved. If your cat scratches the rug, try a horizontal scratcher. If they stretch up on furniture, try a tall vertical one.

Make sure a scratching post is stable. A wobbly post can scare a cat away. For adult cats, the post should be tall enough for a full body stretch, not just a short kitten sized pole.

Vertical space can help cats feel secure, but you do not have to buy a giant tree before you know your cat. A cleared windowsill, sturdy low shelf, or chair near a safe perch can be enough at first. For more ideas, read creating vertical space for cats.

Play is also part of indoor cat care. A bored indoor cat may overeat, wake you at night, scratch more, or pick fights with other pets. Paaw's guides to keeping an indoor cat busy and how much playtime cats need can help once you know your cat's energy level.

Avoid toys with loose bells, glued on eyes, feathers that pull out easily, or thin elastic that can be swallowed. Check toys often and throw away damaged ones. The safest toy is the one your cat enjoys and you can supervise well.

What can wait until you know your cat better?

Many cat purchases can wait. Your cat's size, age, health, coat, confidence, and play style will tell you more than a shopping list can. Waiting a week or two often saves money and prevents clutter.

Fancy beds can wait because many cats choose a cardboard box, a folded blanket, or the carrier over the bed you picked. If you want a bed on day one, choose something washable and simple. Do not be offended if your cat ignores it.

A large cat tree can also wait unless you already know your cat loves climbing. Some senior cats need lower steps and wide platforms. Some shy cats prefer covered cubbies. Some bold young cats want height and a view. Buying later helps you choose the right shape.

Fountains are useful for some cats, especially cats who drink more from moving water, but a clean bowl is fine to start. Automatic feeders can help with schedules later, but they are not needed for the first night. Learn your cat's appetite and routine before relying on a machine.

Stroller gear, backpacks, costumes, and adventure harnesses should wait. Your new cat needs to feel safe indoors before you add strange clothing, street noise, or travel. Some cats never enjoy those things, and that is fine.

Specialty grooming tools depend on coat type. A short haired cat may only need a simple brush. A long haired cat may need combing several times a week to prevent mats. If shedding is your main worry, start with Paaw's guide to managing cat hair at home before buying every brush on the shelf.

Treats can wait or stay very limited. Too many new treats can cause stomach upset, and you will not yet know what your cat tolerates. If you use treats for bonding, offer tiny pieces and keep the main diet steady.

The best reason to wait is that your cat will show you what they use. A cat who scratches cardboard every day may not need a pricey post right away. A cat who sleeps on the windowsill may need a safe perch more than a bed. Let real behavior guide the next purchase.

What should you do the day you bring your cat home?

On pickup day, keep the plan quiet and boring. Bring the carrier, go straight home, and keep the carrier closed in the car. Do not stop for errands, pass the cat around, or open the carrier to comfort them while parked.

When you get home, take the carrier straight to the safe room. Close the room door before you open the carrier. Then open the carrier door and let your cat come out on their own. If they stay inside, that is okay. The carrier can be their first hiding spot.

Sit nearby if your cat seems curious, but do not reach in and pull them out. Speak softly, move slowly, and give them room. Some cats explore within minutes. Some wait until the room is dark and quiet.

Show the setup by leaving it obvious, not by forcing the cat to interact with it. Food and water should be easy to smell and find. The litter box should be visible from the carrier or close enough that the cat finds it during a cautious walk around the room.

Expect quiet behavior, hiding, and maybe a skipped meal on the first night. Many cats eat, drink, or use the litter box after everyone goes to bed. You can sprinkle a small amount of clean litter over waste in the morning if you need to confirm the box was used, but do not hover all night.

Keep visitors away for the first day. If you have children, coach them to use quiet voices and let the cat approach. If you have other pets, keep them separated until you have a slow introduction plan. Rushing introductions can make the first week much harder.

Before bed, check that the door latches, windows are closed, food and water are fresh, and the litter box is clean. A night light can help you enter quietly if needed. Do one last visual safety check for cords, string, plants, and tiny objects.

If you want a step by step plan for the first evening, read your new cat's first 24 hours at home. For the bigger picture, keep how long it takes an adopted cat to adjust handy, since many cats need days or weeks before they act like themselves.

Frequently asked questions

How much should I spend before bringing a cat home?

Spend on the essentials first, not every cute item in the aisle. Your must haves are a secure carrier, litter box, litter, familiar food, food and water bowls, a safe room setup, a scratcher, basic toys, ID, and cleaning supplies. Costs vary a lot by store, brand, and what you already own, so it is better to make a short list than chase a target number. Buy small amounts of food and litter at first if you can. Bigger purchases, like a cat tree or fountain, can wait until you know what your cat actually uses.

Do I need two litter boxes for one cat?

Two litter boxes for one cat are helpful when you have the space, but one clean, easy to reach box can work at first. The common rule is one box per cat plus one extra, so two boxes for one cat is a good goal. If you live in a small apartment, start with one roomy box in the safe room and scoop it daily. Add a second box when you open more of the home, especially if the first box is far from where your cat spends time.

Should I buy a cat tree before my cat arrives?

You can wait to buy a cat tree unless you already know your cat loves climbing. A large tree is not a day one need. Many cats spend the first few days hiding low, while others want height quickly. Start with a safe room, a scratcher, and maybe a simple perch like a cleared windowsill or sturdy chair. Once you see whether your cat likes high places, cubbies, wide platforms, or low steps, you can choose a tree that fits their body and confidence level.

What should I bring when I pick up my adopted cat?

Bring a secure carrier, your ID, payment if the shelter requires it, and a way to carry paperwork home safely. The carrier should close firmly and be lined with a towel or washable pad. Do not plan to hold the cat in your arms in the car, even for a short drive. Ask for adoption records, vaccine history, microchip details, spay or neuter status, medication instructions, and the food the cat has been eating. Then go straight home and take the carrier to the safe room.

Should I let a new cat explore the whole house right away?

Most new cats should start in one quiet room instead of exploring the whole house right away. A safe room lowers stress and makes food, water, hiding, and the litter box easy to find. Some confident cats seem ready to explore quickly, but it is still smart to give them a calm starting point for at least the first day. Open more space slowly once your cat is eating, using the litter box, and approaching you or the door with relaxed body language.

What if my new cat will not eat the first night?

A new cat skipping food the first night can be normal if they are alert, hiding, and otherwise stable. Offer the familiar food from the shelter, place it near but not inside the hiding area, and leave the room quiet. Many cats eat after people go to bed. Call a vet if your cat eats nothing for 24 hours, refuses water, vomits repeatedly, has diarrhea, seems weak, or has a known health condition. Kittens, senior cats, and cats with medical problems need faster advice.

Do indoor cats need ID tags?

Yes, indoor cats should have ID, especially during the first few weeks in a new home. New cats may hide, panic, or slip through a door before they know where they live. A microchip is important, but a visible tag can help a neighbor call you right away. Use a breakaway collar made for cats and keep the tag simple, with your phone number and possibly an indoor cat note. Also confirm that the microchip registration has your current contact information.

What should I ask the shelter before adoption day?

Ask practical questions that help you keep the first week familiar. Find out what food and litter the cat uses, their feeding schedule, known medical history, vaccine record, spay or neuter status, microchip number, and any medications. Ask what the cat was like in the shelter: shy, social, active at night, playful, nervous around dogs, or sensitive to handling. Also ask whether they used a covered or uncovered litter box. These details help you set up the room and avoid sudden changes.
