Bringing home a new cat is exciting — and a little overwhelming. The first week sets the foundation for how your cat adjusts, bonds with you, and settles into their new environment. This checklist walks you through everything you need to do before your cat arrives, what to expect on day one, and how to support them through their crucial first week.
Before Your Cat Arrives: Setup Checklist
The work starts before your cat walks through the door. Setting up their space ahead of time reduces stress for both of you and ensures your cat has everything they need from the moment they arrive.
Essential Supplies
- Litter box: At least one box, preferably uncovered and large enough for your cat to turn around comfortably. See our Litter Box Setup Guide for placement and type recommendations.
- Litter: Start with unscented, clumping clay litter — it’s what most cats are familiar with. You can transition to other types later if needed.
- Food and water bowls: Wide, shallow bowls prevent whisker fatigue. Stainless steel or ceramic are best — they’re easy to clean and won’t harbor bacteria.
- Food: Buy the same brand your cat has been eating. Sudden diet changes can cause stomach upset. Transition gradually to a new food if desired.
- Scratching post: At least one tall, stable post covered in sisal. Cats need to scratch — give them an appropriate outlet.
- Hiding spots: A cardboard box, cat bed, or covered hideaway. New cats need somewhere to retreat and feel safe.
- Toys: A few interactive toys like wand toys and small ball toys. Play helps burn off stress and builds your bond.
- Carrier: A sturdy, hard-sided carrier large enough for your cat to stand and turn around. You’ll need it for vet visits and emergencies.
Prepare a Safe Room
Your new cat shouldn’t have free run of the house on day one. Instead, set up a single quiet room — a bedroom, office, or spare room — as their home base. This small, controlled space reduces overwhelm and gives your cat a secure territory to claim first.
In this room, place:
- Litter box in one corner
- Food and water bowls in the opposite corner (cats don’t like eating near their bathroom)
- Scratching post
- Hiding spot
- A few toys
Close off any small gaps behind furniture where a frightened cat could get stuck. Remove anything breakable or hazardous.
Cat-Proof Your Home
Before your cat explores beyond their safe room, walk through your home and secure:
- Electrical cords (cats may chew them)
- Toxic plants (lilies, pothos, dieffenbachia, and many others are poisonous to cats)
- Open windows without secure screens
- Medications, cleaning supplies, and small objects that could be swallowed
- Unstable furniture that could tip if climbed

Day One: Arrival and First Impressions
The first 24 hours are critical. Your cat is processing an enormous amount of new information — new smells, new sounds, new people. Your job is to minimize stress and let your cat set the pace.
The Homecoming
When you arrive home, take your cat directly to their safe room. Open the carrier door and step back. Do not reach in and pull your cat out — let them exit on their own timeline. Some cats will explore immediately. Others will stay in the carrier for hours. Both are normal.
Sit quietly in the room and let your cat investigate. Speak softly. Offer a treat or two. Don’t force interaction. If your cat hides under the bed or in their box, that’s okay. They’re processing.
What to Expect on Day One
- Hiding: Completely normal. Your cat is overwhelmed and needs time to assess their new environment. Give them space.
- Not eating: Also normal. Stress suppresses appetite. As long as your cat drinks some water and uses the litter box, a day without eating is not an emergency.
- Excessive meowing: Some cats vocalize when stressed or confused. Others go silent. Both are normal stress responses.
- Hyperactivity: Some cats respond to stress by exploring frantically or playing hard. This can be a release valve for nervous energy.
First Night Routine
Keep your cat in their safe room overnight. Close the door so they can’t wander and get spooked by unfamiliar nighttime sounds. Leave a nightlight on if the room is very dark.
Don’t be surprised if your cat is awake and active at night — cats are naturally crepuscular (most active at dawn and dusk). You may hear them playing with toys or using the litter box. That’s a good sign.
Week One: Building Routine and Trust
The first week is about establishing predictability. Cats thrive on routine, and a consistent schedule helps your new cat understand what to expect.
Daily Routine to Establish
- Feeding times: Feed at the same times every day — ideally morning and evening. Scheduled meals (rather than free-feeding) help you monitor appetite and prevent obesity.
- Play sessions: 15–20 minutes of interactive play twice a day. Use a wand toy to mimic prey movement. Play before meals mimics a natural hunt-eat cycle and helps your cat bond with you.
- Quiet time: Spend time in the room with your cat without forcing interaction. Read, work on your laptop, or just sit. Your presence becomes part of their safe environment.
Gradual Socialization
Let your cat initiate contact. Sit on the floor (you’re less intimidating at their level) and let them approach you. Offer slow blinks — in cat language, this signals trust and calm. Avoid direct staring, which can feel threatening.
If your cat allows it, offer a finger to sniff. Let them rub their cheeks on your hand — this is scent-marking, a sign they’re beginning to feel comfortable. Progress to gentle head scratches and chin rubs. Stop if your cat pulls away or shows signs of overstimulation (tail flicking, ears back, dilated pupils).
Expanding Territory
Most cats are ready to explore beyond their safe room after 3–7 days, though timid cats may need longer. When your cat seems confident — eating normally, using the litter box, seeking interaction, playing — you can start opening up access to the rest of the house.
Do this gradually:
- Open the door to the safe room and let your cat explore at their own pace
- Keep the safe room accessible so they can retreat if overwhelmed
- Supervise early explorations
- Add additional litter boxes in other parts of the house (one per cat plus one extra is the standard recommendation)
What to Watch For
During the first week, monitor for signs your cat is adjusting well — or signs something is wrong.
Good signs:
- Eating and drinking normally (within 48 hours)
- Using the litter box consistently
- Grooming themselves
- Playing or showing curiosity
- Seeking interaction with you
Concerning signs (call your vet):
- Not eating for more than 48 hours
- Not using the litter box (especially not urinating — this is an emergency)
- Labored breathing or persistent coughing
- Discharge from eyes or nose
- Diarrhea or vomiting
- Extreme lethargy

Common First-Week Challenges
My cat won’t come out of hiding
Give them more time. Some cats take a full week or longer to feel secure enough to explore. Make sure food, water, and the litter box are accessible from their hiding spot. Sit in the room and talk softly so they get used to your voice. Avoid dragging them out — this will only make them more fearful.
My cat is eating very little
Stress suppresses appetite. As long as your cat is eating something and drinking water, a reduced appetite for the first few days is normal. Try offering high-value treats like plain cooked chicken or a small amount of tuna. Warming wet food slightly can make it more appealing. If your cat goes more than 48 hours without eating, call your vet.
My cat is meowing constantly
Your cat may be confused, anxious, or looking for attention. Respond calmly — speak softly, offer play or petting if they seem receptive. Consistent routine helps reduce anxiety-driven vocalization. If the meowing is accompanied by signs of distress (pacing, panting, dilated pupils), consult your vet.
My cat is avoiding the litter box
First, rule out medical issues — urinary problems can cause litter box avoidance and require immediate vet care. If your cat is healthy, consider:
- Is the box clean? Cats are fastidious and may avoid a dirty box.
- Is the litter type or box location stressing them out?
- Is the box too small or covered (many cats dislike covered boxes)?
- Is the box in a high-traffic or noisy area?
See our Litter Box Setup Guide for troubleshooting tips.
Building a Foundation for Long-Term Wellness
The first week is just the beginning, but the habits you establish now set the tone for your cat’s entire life with you. Prioritize:
- Routine: Consistent feeding, play, and interaction times
- Enrichment: Daily play, scratching opportunities, and mental stimulation. See our Indoor Cat Enrichment Guide for ideas.
- Health monitoring: Track eating, drinking, litter box use, and behavior. Early detection of problems makes treatment easier.
- Veterinary care: Schedule a wellness exam within the first week if possible, or within the first month. Establish a relationship with a vet before an emergency happens.
