Setting Up Your Home for a New Cat: A First-Week Checklist

Oct 14, 2026 ·

Bringing home a new cat is exciting, and a little nerve-wracking. You want everything to go smoothly, and your new cat wants one thing above all else: to feel safe.

The first week sets the tone for your life together. Cats are creatures of routine and territory, and moving to a new home is a big upheaval for them. The smells, sounds, and spaces are all unfamiliar, so even the friendliest cat may hide, skip meals, or act shy at first. That is completely normal, and a little preparation helps enormously.

The good news is that you do not need a lot of fancy gear. What your cat truly needs is a quiet space, a clean litter box, fresh food and water, somewhere to hide, and a calm human who gives her time. This guide walks you through each of these, step by step, and ends with a simple day-by-day checklist you can follow.

Whether you are adopting a kitten, a grown cat, or a senior, the same principles apply. Go slowly, let your cat set the pace, and remember that patience is the most valuable item on your shopping list.

Before She Arrives: Prepare a Safe Starter Room

The single best thing you can do is set up one small room just for your new cat. A spare bedroom, a quiet office, or even a large bathroom works well. Think of it as her base camp.

Why start small?

A whole house can feel overwhelming to a cat who has just arrived. A single room is easier to learn and easier to feel safe in. Once she is relaxed and exploring confidently, you can open up the rest of the home gradually, usually after several days.

What the room should have

• A door that closes securely, so she cannot slip out and you can keep other pets and young children away at first.
• A quiet location, away from loud appliances, busy hallways, and front-door traffic.
• Everything she needs in one place: litter box, food, water, a hiding spot, a scratcher, and a few toys.
• A comfortable resting area, such as a soft blanket or bed near (but not next to) the litter box.

Quick safety sweep

Get down on your hands and knees and look around the room from a cat’s height. Remove or secure anything she could chew, swallow, or squeeze behind:

• Loose cords and blind strings
• Small objects such as hair ties, rubber bands, and string
• Toxic houseplants (lilies are especially dangerous to cats)
• Gaps behind appliances or furniture where she could get stuck
• Open windows without secure screens

Litter Setup: Getting the Bathroom Basics Right

Litter problems are one of the most common reasons cats end up in shelters, and most of them are preventable. A good setup from day one makes a big difference.

Choose the right box

• Size: the box should be about one and a half times the length of your cat’s body, so she can turn around and dig comfortably. Many standard boxes are too small.
• Open or covered: most cats prefer open boxes, which feel less cramped and let them see what is around them. If you choose a covered one, make sure the entrance is easy to use.
• Kittens and seniors: choose a box with low sides so tiny legs or stiff joints can step in easily.

Pick a gentle litter

Most cats prefer unscented, fine-grained, clumping litter, since it feels soft under their paws. Strong perfumes can put a cat off, even if they smell pleasant to you. If you know what litter your cat used before, start with that, then change gradually later if you want to.

Where to put it

Place the box in a quiet, easy-to-reach spot, away from her food and water. Cats do not like to eat near where they go to the toilet. Avoid putting it next to a noisy washing machine, where a sudden rumble could scare her.

How many boxes?

The common rule is one box per cat, plus one extra. In the first week, one box in her starter room is enough, but plan ahead if you will have more cats or a multi-level home.

Keeping it clean

Scoop at least once a day and wash the box with mild, unscented soap every week or two. A clean box is one of the best ways to keep your cat happy and using it reliably. If she has an accident, do not scold her. Clean it thoroughly with an enzyme cleaner and look for a cause, such as stress, a dirty box, or a health issue.

Food and Water: Keeping Mealtime Calm

Stress can dampen a new cat’s appetite, so mealtime should be as simple and predictable as possible.

Start with what she already eats

Ask the shelter, breeder, or previous owner what brand and type of food she has been eating, and buy a small supply of the same one. Changing food at the same time as changing homes is a lot for her digestion. If you want to switch later, wait until she has settled, then transition over 7 to 10 days by mixing the new food into the old.

Choose a complete and balanced food that matches her life stage: kitten, adult, or senior. For portion guidance, follow the label as a starting point and check in with your vet.

Bowls and placement

• Use wide, shallow bowls made of stainless steel or ceramic, which are easy to clean and gentle on whiskers.
• Put food and water in separate spots, a little apart from each other. Many cats prefer their water away from their food.
• Keep bowls away from the litter box, ideally on the opposite side of the room.
• Place them where she can see the door from her eating spot, since cats feel safer when they are aware of their surroundings.

Feeding in the first week

Offer small meals at regular times, usually two a day for adults and three or four for kittens. Do not worry if she eats very little on the first day. Many cats are too nervous to eat right away. Leave quiet time around meals and avoid hovering.

Fresh water should be available at all times, so change it daily. If she is not eating at all after a day, or seems unwell, it is time to call your vet.

Hiding Spots and Safe Spaces: Why Cats Need to Disappear

If your new cat dives under the bed the moment she arrives, do not take it personally. Hiding is a natural coping strategy. For a cat, being able to retreat is what makes it possible to eventually relax and explore.

Easy ways to create hiding spots

• A cardboard box on its side with a soft towel inside. It is free, cozy, and cats love it.
• A covered cat bed or cave, which gives her a snug place to rest.
• A blanket draped over a chair or table to form a tent.
• Space under the bed or behind furniture, if it is safe and you can still reach her in an emergency.

Let her choose where she feels comfortable. Do not pull her out of hiding or block her in. Instead, sit quietly nearby, read a book, or speak softly. Over time, curiosity wins.

Think vertical

Cats feel safest when they can observe from above. A sturdy cat tree, a shelf, or the top of a stable bookshelf gives her a lookout point. In a starter room, even a sturdy chair by the window can be enough.

A window with a view

A perch near a safe, secure window offers entertainment, from birds to passing cars. Make sure screens are firmly in place so she cannot push through.

Respect her signals

Hiding for several days is common, especially for shy cats. As long as she is eating, drinking, and using the litter box, give her space. If she refuses food or water for more than a day, contact your vet.

Scratching, Toys, and Cat-Proofing Your Home

Scratching posts

Scratching is not bad behavior. It is how cats stretch, mark territory, and keep their claws healthy. The trick is giving her something better than your sofa.

• Choose a sturdy post that will not wobble when she pulls on it.
• Make sure it is tall enough for a full stretch, about 30 inches or more for an adult.
• Offer both vertical and horizontal options, since cats have different preferences. Sisal rope and cardboard are popular choices.
• Place scratchers near sleeping spots and room entrances, where cats like to stretch.

If she scratches the wrong thing, gently redirect her to the post and reward her when she uses it.

Toys and play

Play keeps your cat fit and helps her build confidence. A few well-chosen toys are better than a giant pile.

• Wand toys let you play interactively, which is great for bonding.
• Small balls and soft mice are good for solo play.
• Puzzle feeders add mental stimulation at mealtime.

Avoid string, yarn, and ribbons unless you are supervising, since swallowed strings can cause serious intestinal problems. Put wand toys away after play.

Cat-proofing the rest of the home

Before she explores beyond her room, do another safety check. Secure windows and balcony doors, tuck away electrical cords, and store medications, cleaning products, and human foods out of reach. Some common household items are toxic to cats, including lilies, onions, garlic, chocolate, grapes, and certain essential oils. If you are unsure whether a plant is safe, check a reliable list such as the ASPCA’s before bringing it home.

Keep trash cans covered and close lids on washers and dryers. Cats are curious, and a quick walk-through now can prevent trouble later.

The First 24 Hours: Bringing Her Home

The journey home can be stressful, so keep things calm from the moment you leave.

The ride home

Use a secure, hard-sided carrier lined with a soft towel. Place it on the floor of the back seat or buckle it in, and avoid opening it in the car. If possible, bring a blanket or toy that smells like her previous home.

Arrival

Carry the carrier straight into her starter room and close the door. Set the carrier on the floor, open the door, and then step back. Do not pull her out. Let her walk out when she is ready, even if that takes an hour or longer.

What to do next

• Sit quietly in the room for a little while, if she seems comfortable with it, and speak softly.
• Avoid loud noises, bright lights, and lots of visitors.
• Let her sniff the room, find the litter box, and discover her food and water.
• Do not insist on cuddles. If she wants them, she will come to you.

What is normal

It is very common for a new cat to hide, eat little, meow more, or seem restless on the first night. Some cats are bold and explore at once, while others take days. Both are fine.

Gentle bonding ideas

Once she seems curious, try slow blinks, which cats read as a friendly gesture. Offer a favorite treat from your hand, or play gently with a wand toy. Keep sessions short and positive, and always end while she is still interested.

Introductions: Family, Children, and Other Pets

Good introductions are slow introductions. Rushing is the most common mistake, and a patient start prevents many problems later.

Family members

Let people meet her one or two at a time, and ask everyone to stay calm and quiet. Sit on the floor, let her come to you, and offer a treat. Avoid picking her up in the first days unless she clearly enjoys it.

Children

Teach children to be gentle before the cat arrives:

• Pet softly with an open hand, along the back, and avoid the tail and belly.
• Never chase, grab, or corner her.
• Leave her alone when she is eating, sleeping, or using the litter box.
• Always supervise young children around a new cat.

Introducing another cat

Cats rely heavily on scent, so start with smell before sight.

1. Keep them separate for the first several days, each in their own space with their own litter box.
2. Swap scents by rubbing a soft cloth on one cat and placing it near the other, or swapping their bedding.
3. Feed on either side of a closed door, moving the bowls a little closer each day, so they link each other’s scent with something pleasant.
4. Allow short visual meetings, such as through a baby gate or cracked door, then reward calm behavior.
5. Supervise brief face-to-face visits and end them before tension builds.

Hissing and growling are common at first. Serious fighting is not, and if it happens, separate them calmly and go back a step. The whole process can take a couple of weeks or longer, and that is perfectly okay.

Introducing a dog

Start the same way, with scent swaps and a closed door. Keep the dog on a leash for early visits and reward calm behavior. Always give the cat an escape route, such as a high perch or a room the dog cannot enter. Some dogs have a strong chase instinct, so if yours reacts intensely to cats, ask a trainer or your vet for guidance before going further.

Your Day-by-Day First-Week Checklist

Use this as a flexible guide, not a strict schedule. If your cat needs more time, simply stay on the same step longer.

Before she comes home

• Set up the starter room with a litter box, food, water, a hiding spot, a scratcher, and toys
• Do a cat-level safety sweep
• Buy a hard-sided carrier and a small supply of her current food
• Find a local vet and book a first visit

The first week

Most vets recommend a first check-up within the first week or two, especially for kittens, cats from unknown backgrounds, and cats that will meet other pets. Bring any adoption or vaccination paperwork with you.

When to Call the Vet in the First Week

Stress can cause small changes in a new cat, such as hiding or eating less. But some signs should never be brushed off, because cats often hide illness until it becomes serious.

Contact your vet promptly if you notice:

• No eating for 24 hours or more, or no drinking. For kittens, call sooner.
• Not using the litter box, straining to urinate, or crying while trying to go. This can be an emergency, especially in male cats.
• Repeated vomiting or diarrhea, or blood in either.
• Sneezing, runny eyes, or coughing that does not clear quickly. Respiratory infections are common in cats from shelters.
• Lethargy, weakness, or hiding that feels more like illness than shyness.
• Limping, wounds, or signs of pain.
• Fleas, ear mites, or skin problems.

A good first vet visit

A first visit is a chance to check her overall health, discuss vaccines, parasite prevention, microchipping, and spaying or neutering if it has not been done, and ask any questions about diet and behavior. Many cats also need a plan for regular check-ups after that.

If you are ever unsure, call. Vet teams would much rather hear from you early than late.

Final Thoughts

The first week with a new cat is less about doing everything perfectly and more about making her feel safe. A quiet room, a clean litter box, regular meals, a place to hide, and plenty of patience will take you most of the way there.

Some cats settle in within hours, and others need weeks to show their full personality. Neither is a sign that something is wrong. Let her lead, celebrate the small wins, like the first purr, the first time she eats in front of you, or the first time she curls up nearby, and trust that the bond will grow.
