Key Takeaways
- Start with a single room so the cat can adjust without feeling overwhelmed by a large space.
- A litter box, food bowl, water source, scratching post, and a secure hiding spot cover your true essentials.
- Most cats take one to three weeks to show their real personality after arriving in a new home.
- Schedule a veterinary visit within the first week, even if the cat appears healthy.
- Wet food supports hydration; always provide fresh water regardless of the diet you choose.

The supplies you actually need
Before your cat arrives, gather the items that cover safety, hygiene, and basic comfort. You do not need every product marketed to cat owners, but skipping a genuine essential creates problems on day one.
Socialization period
The window in a kitten's development, roughly two to seven weeks of age, when positive exposure to people, sounds, and handling shapes long-term behavior and temperament.
Core vaccines
Vaccines recommended for all cats regardless of lifestyle, typically including protection against feline herpesvirus, calicivirus, panleukopenia, and rabies.
Free-feeding
Leaving dry food available at all times rather than providing measured meals at set times. This practice can make it difficult to monitor appetite and control calorie intake.
Enrichment
Activities and objects, such as climbing structures, puzzle feeders, or interactive toys, that give cats mental and physical stimulation inside the home.
Cat-proofing
Removing or securing household items that could harm a cat, including toxic plants, unsecured cords, small objects that can be swallowed, and gaps where a cat could become trapped.
- Litter box: at least one, sized so the cat fits inside with room to turn
- Cat litter: unscented clumping litter works for most cats
- Food and water bowls: shallow ceramic or stainless steel bowls are easy to clean
- Cat food: choose a formula appropriate for the cat's age (kitten, adult, or senior)
- Scratching post: at least one, tall enough for the cat to fully stretch
- Carrier: essential for transport and vet visits
- Hiding spot: a cardboard box with a cut-out opening costs nothing and matters a lot
Toys are useful for mental stimulation but are not urgent on arrival day. If you already have a dog or other cat at home, the introduction process follows a separate approach. See our guide to introducing a second cat for a phased method that keeps territorial stress low.
Setting up your home before arrival
Cat-proofing focuses on two things: removing hazards and creating a defined starting zone.
Hazards to address
Secure or hide electrical cords. Check that window screens are firmly fitted, since cats push against them. Remove or relocate plants that are toxic to cats; the ASPCA maintains a searchable list of toxic and non-toxic plants at aspca.org. Store cleaning products, medications, and rubber bands in closed cabinets.
The starting room
Choose a quiet, low-traffic room as the cat's base for the first few days. Place the litter box at one end, food and water bowls at the other, and the hiding spot somewhere in between. Cats feel more secure when resources are separated rather than clustered together. Once the cat is eating and using the litter box without hesitation, you can open access to the rest of the home gradually, one room at a time.
The first 24 to 72 hours
Arrival day is stressful for most cats. The goal is to give the cat control over how quickly it engages with the new environment.
Open the carrier inside the starting room and step back. Let the cat come out on its own timeline. Avoid the impulse to carry the cat around for introductions to family members; that can increase anxiety rather than reduce it.
Keep noise low. Children and other pets should stay out of the starting room for at least the first 24 hours. Provide food and fresh water and check the litter box without hovering. If the cat hides for most of the first day, that is normal behavior, not a sign that something is wrong.
Talk to the cat in a calm, low voice when you enter the room. Sit on the floor rather than standing, which is less imposing from a cat's perspective. Let the cat approach you first. Most cats begin to show curiosity within 48 hours, though some need longer.
Food, water, and litter basics
Match food to life stage
Kitten food has higher protein and calorie levels than adult formulas because kittens grow rapidly. Switch to an adult formula around one year of age, or follow your vet's recommendation based on the cat's size and health. Senior formulas are generally appropriate from around seven years of age onward.
Feeding
Cats need animal-based protein; they cannot meet their nutritional needs on a plant-based diet. A combination of wet and dry food is common in practice. Wet food provides moisture, which supports kidney and urinary tract health because cats have a low thirst drive by nature. Feed measured portions rather than leaving dry food out all day, since free-feeding is associated with weight gain in indoor cats.
When switching food from whatever the previous owner or shelter used, mix the new food in gradually over seven to ten days to avoid digestive upset.
Water
Place water away from the food bowl. Many cats drink more reliably when the water source is in a different spot from their food. A wide, shallow bowl works well; some cats prefer a running water fountain.
Litter box maintenance
Scoop the box at least once a day. A dirty box is the most common reason cats choose another location. Keep the box in the same spot; cats are creatures of habit and dislike surprise relocations of their facilities.
Health care in the first weeks
Schedule a veterinary exam within the first seven days, even if the cat came with health records. A vet will check for parasites, assess body condition, confirm vaccination status, and discuss spay or neuter timing if that has not already been done.
For kittens, the vaccine schedule typically runs from around eight weeks of age through 16 weeks, with boosters spaced three to four weeks apart. Our plain-language breakdown of cat vaccinations explains which vaccines are considered core and what the typical schedule looks like.
Watch for these signs in the first weeks and contact a vet if you observe them: sneezing or nasal discharge lasting more than two days, loose stool or no stool for more than 48 hours, refusal to eat beyond 24 hours, labored breathing, or visible parasites such as fleas.
Grooming is another area to start early. Getting a cat comfortable with being touched, having its nails trimmed, and tolerating brief handling makes all future care easier. Our guide to grooming a cat at home covers the step-by-step approach for making that a calm routine.
