🐱 How to Set Up Your Home for a New Cat

Cats settle into a new home fastest when the space is ready before they arrive, so a little preparation goes a long way. The cat is a territorial animal that needs to feel safe and in control, and the single most helpful thing you can do is set up a calm, welcoming space in advance.

Set up a quiet base camp

Rather than giving a new cat the run of the whole house on day one, start with one quiet "base camp" room — a spare room or even a bathroom works well. Stock it with food, water, a litter box, a scratching post, and a cozy hiding spot. Let your cat decompress here for a few days, getting comfortable with the sounds and smells of their new home before they explore the rest of the house at their own pace. This slow introduction helps nervous cats relax and prevents them from feeling overwhelmed.

Litter box basics

Litter boxes are one of the most important things to get right. The classic rule is one box per cat, plus one extra — so a single cat needs two boxes. Place them in quiet, easy-to-reach spots away from where people cook or eat, and scoop them daily, washing hands afterwards. If anyone in the house is pregnant, someone else should do the scooping. Keep food and water away from the litter, since cats dislike eating right next to their bathroom. Most cats prefer a large, uncovered box with plain, unscented clumping litter — simple and familiar tends to beat fancy every time.

Scratching and climbing are needs, not extras

Scratching and climbing are natural, healthy behaviors, not bad habits to train away. Give your cat a sturdy scratching post that is taller than they are when stretched to full length and stable enough that it will not tip over. Add vertical space too, like a cat tree or a window perch. Height helps indoor cats feel safe and secure — and it saves your furniture. Round it out with toys and daily play to keep your cat active and happy — our guide to the best cat toys splits them into the ones you play with together and the ones that work while you are out.

Cat-proof your home

Before your cat explores, make the house safe. Secure window screens so a curious cat cannot push through, tuck away or secure electrical cords, and put away small items that could be swallowed. Be especially careful with houseplants: lilies are extremely dangerous to cats, so keep them out of the house altogether. Every part of a lily can badly damage a cat's kidneys, even the pollen and the water in the vase. Check that other plants are cat-safe too. A quick sweep for hazards now prevents scary accidents later.

Food, water, and vet care

Feed a complete, balanced cat food and always keep fresh water available — some cats drink more happily from a pet water fountain. Book an initial vet visit for a checkup and vaccinations, and ask about a microchip and ID so your cat can be identified if they ever slip outside. Finally, keep up daily play and enrichment, which prevents boredom and the problem behaviors that come with it. If allergies are a concern for your household, our guide to hypoallergenic pets is worth a look.

🧽 Cleaning & maintenance

Scoop the litter box daily — most litter-box problems start with a dirty box — and fully change the litter and wash the box with mild, unscented soap every week or two. Wash food and water bowls daily, vacuum up litter and hair, and clean the scratching areas and bedding regularly. Keep an enzymatic cleaner on hand for the occasional accident or hairball; it removes the odor so your cat is not tempted back to the spot. Avoid strong-smelling cleaners near the box, since a perfumed box can put a cat off using it.

⚠️ Common cat setup mistakes

Already have one and something feels off? Start here. These catch almost everybody — none of them mean you have done badly, and every one of them is fixable.

Where should I put my cat's litter boxes?

The mistake: Lining both litter boxes up together.

Two boxes side by side count as one bathroom to a cat: one cat can guard both, and one fright puts them off both at once. Behavior vets ask for boxes in different rooms with several feet between them, and one on every floor of the house.

Try this: Move one box to another room or another floor, somewhere quiet with two ways out, and away from a washer or furnace that can bang on without warning. Moving a box costs nothing, and it solves most going-in-the-wrong-place problems.

Are lilies safe if I keep them up high?

The mistake: Keeping lilies out of reach, not out.

Every part of a lily is dangerous — leaves, flowers, pollen, and even the water in the vase. Pollen drifts onto shelves and onto a cat's coat and gets swallowed during grooming, and kidney failure can follow within a couple of days.

Try this: No true lilies or daylilies in the house at all, including in bouquets that arrive as gifts — check before they come through the door, and ask for a lily-free bunch. If your cat has chewed a lily or licked the vase water, that's an emergency vet visit within hours, not tomorrow.

Is string dangerous for cats?

The mistake: Leaving string, hair ties and ribbon out.

A cat can't spit string back out — their tongue is built to pull things backwards, so it goes down. Once one end catches, the gut gathers up along the thread and it saws through from the inside, which means emergency surgery.

Try this: Hair ties, rubber bands, dental floss, sewing thread and gift ribbon go in a closed drawer, and wand toys with dangly strings live in a closet between play sessions. If you can see string hanging out of your cat at either end, never pull it — go straight to a vet.

Are essential oil diffusers safe for cats?

The mistake: Running an essential oil diffuser at home.

Cats are short of the liver enzyme that breaks these oils down, so they build up instead. A diffuser settles a fine mist on the coat and the cat swallows it while grooming — tea tree, citrus, pine, peppermint, wintergreen and ylang ylang are among the riskiest.

Try this: Switch the diffuser off: free, and it works straight away. Open a window instead, and keep simmering liquid potpourri out of the house entirely. If your cat is drooling, unsteady, or breathing strangely, call a vet now.

Why does my cat ignore the scratching post?

The mistake: Putting the scratching post in a spare room.

Cats scratch to leave their mark where they actually live, so a post in a room nobody uses gets ignored while the couch by the door keeps getting shredded.

Try this: Move the post right next to whatever they're already scratching, and add one where they sleep — cats stretch and scratch the moment they wake up. Rough sisal beats carpet, and once they're using it you can shift it a few inches at a time toward a spot you like better.
