The Complete Guide for New Cat Owners
On this page
A new cat needs less gear and more patience than most first-time-owner checklists suggest. Here is what actually matters, in the order it tends to come up: before they arrive, the first days, and the first couple of weeks.
This guide is written from published veterinary sources, named and linked as they come up and listed again at the bottom.
What to buy before your cat arrives
The essentials: a litter box and litter, food and water bowls, a carrier, a scratching post, a bed, and a few toys. Everything else, including a particular food brand or a second scratching post, can wait until you know your cat's preferences rather than guessing them in advance.
Cat-proofing the house
Lilies are the single most important thing to know here: every part of the plant, including the pollen and even the water in a vase, is highly toxic to cats and, according to the FDA, can cause fatal kidney failure in less than three days from a small exposure. If there are any lilies in the house, they need to come out before a cat moves in. The Cornell Feline Health Center lists other common toxic plants, including poinsettias, tulips and philodendron, and our guide to toxic plants for cats sorts the deadly ones from the merely irritating.
Beyond that, walk the house at cat height. Secure or hide dangling cords, especially blind cords, which are a strangulation risk. Remove small objects a cat could swallow, and keep cleaning products and anything from the list of foods toxic to cats somewhere they cannot reach. Keep washing machines and dryers closed between loads, since a cat climbing into one unnoticed is a genuine and recurring cause of injury. Check window screens are secure too; cats misjudge falls from height more often than owners expect.
The first 24 to 48 hours
Start with one quiet room rather than the whole house. Set up their litter box, food, water and a hiding spot inside it, and let them come out and explore on their own schedule rather than being carried around or introduced to everyone at once. Most cats relax faster with less handling in the first days, not more. Hiding, a reduced appetite and low activity are normal in this window; if any of that continues much past a week or two, or your cat stops eating entirely, it is worth a call to the vet.
Litter box basics
The usual guidance, which the Cornell Feline Health Center repeats, is one litter box per cat, plus one extra, placed in quiet, easily accessible spots away from food and water. For a single new cat, that means two boxes is a safer starting point than one, particularly while they are still learning the house. Avoid moving a box once it is established somewhere; a cat that has to relearn where to go is more likely to have accidents elsewhere.
Setting up a feeding routine
A consistent feeding schedule, with a food matched to their life stage, is one of the more settling things you can offer a new cat. Our feeding guide covers how much to feed by weight, and our cat age calculator helps place a new cat's age against the life stage that determines what kind of food they need.
The first vet visit
Book one within the first week if you can, even if your cat seems completely healthy. A first visit establishes a baseline, confirms vaccinations and parasite prevention are current or gets them started, and is the right time to raise microchipping and spay or neuter timing if either has not already been done. The clinic will also ask for your cat's name, so if you are still deciding, our cat name generator shortlists names that come with a real meaning behind them. Adopting in the autumn? Our list of Halloween cat names has more than 200 ideas, each with its meaning.
Understanding early behavior
Scratching is a normal, necessary behavior, not something to punish; redirecting a cat to a scratching post works far better than telling them off. As Cornell puts it, cats see no link between a punishment and the "crime", so punishment only teaches them to fear you. Kneading, sometimes called making biscuits, is a comfort behavior many cats carry from kittenhood, and our guide to why cats knead covers what it means when they do it to you.
Learning to recognize when something is actually wrong, rather than normal settling-in behavior, matters just as much early on. Our guide to the early signs a cat is sick is worth reading before you need it.
Introducing other pets
Slowly, and only once the new cat is comfortable in their own space. A gradual introduction through a closed door, then brief, supervised visits over a week or more, goes better than a first meeting with no barrier at all. Rushing this step is one of the more common causes of lasting tension between cats in the same home.
Frequently asked questions
What do I need to buy before bringing a cat home?
The essentials: a litter box and litter, food and water bowls, a carrier, a scratching post, a bed, and a few toys. Everything else, including a particular food brand or a second scratching post, can wait until you know your cat's preferences rather than guessing them in advance.
How do I help a new cat settle in?
Start with one quiet room rather than the whole house. Set up their litter box, food, water and a hiding spot in it, and let them come out and explore on their own schedule rather than being carried around or introduced to everyone at once. Most cats relax faster with less handling in the first days, not more.
When should I take a new cat to the vet?
Within the first week if possible, even if they seem completely healthy. A first visit establishes a baseline, confirms vaccination and parasite prevention are up to date or gets them started, and is the right time to discuss microchipping and spay or neuter timing if that has not already been done.
What plants are toxic to cats?
Lilies are the one to know above all others: every part of the plant, including pollen and the water in a vase, is highly toxic to cats and can cause fatal kidney failure from a small exposure. If you keep any lilies in the house, they need to come out before a cat moves in, not after.
How many litter boxes do I need?
The usual guidance is one box per cat, plus one extra, placed in quiet, easily accessible spots away from food and water. For a single new cat, that means two boxes is a safer starting point than one, particularly while they are still learning the house.
How long does it take for a cat to adjust to a new home?
Anywhere from a few days to a few weeks, and it varies a lot by individual cat and by how they came to you. Hiding, reduced appetite and low activity in the first days are normal; if any of those continue much past a week or two, or your cat stops eating entirely, it is worth a call to the vet rather than assuming it will pass.
When can I introduce my new cat to other pets?
Slowly, and only once the new cat is comfortable in their own space. A gradual introduction through a closed door, then supervised, brief visits, over a week or more, goes better than a first meeting with no barrier. Rushing this step is one of the more common causes of lasting tension between cats.
