The First Week With a New Cat: Day-by-Day Guide for First-Time Owners
- Set up one quiet starter room before your cat comes home with a litter box, food, water, hiding spot, bed, scratching surface, and carrier nearby.
- Expect hiding, reduced appetite, and less play for the first 24 to 72 hours. Many cats need several days to relax enough to show their normal personality.
- Keep food and water away from the litter box, and plan for at least one litter box per cat plus one extra in the home.
- Schedule a wellness visit within the first week if records are incomplete, your cat is newly adopted, or you have questions about vaccines, FeLV/FIV testing, parasite control, microchipping, or spay/neuter timing.
- Call your vet promptly if your cat has not eaten for 24 hours, is straining in the litter box, has vomiting or diarrhea that continues, or shows open-mouth breathing.
Getting Started
Bringing home a new cat is exciting, but the first week can feel surprisingly quiet. Many cats hide, eat less than usual, or avoid interaction at first because a new home is a major change. That does not always mean something is wrong. It often means your cat needs time, routine, and a smaller space to feel safe.
Start with one calm room instead of giving full access to the whole home on day one. Include a litter box, fresh water, food dishes, a bed or blanket, a sturdy scratching surface, and at least one hiding option. Keep food and water well away from the litter box, and clean the box often. Most cats prefer a clean box and unscented, fine-textured litter.
Your first week is less about training and more about observation. Watch appetite, water intake, litter box use, breathing, energy, and body language. A shy cat may still be healthy, but a cat who has not eaten for 24 hours, is straining to urinate, or is breathing with an open mouth needs prompt veterinary attention.
If your cat came from a shelter, rescue, breeder, or previous home, gather all records and share them with your vet. That first visit helps confirm vaccine status, discuss FeLV/FIV testing when appropriate, review parasite prevention, and make a plan that fits your cat, your household, and your budget.
Your New Pet Checklist
Home setup essentials
- ☐ Litter box
Choose a box large enough for an adult cat. Low sides help kittens and senior cats.
- ☐ Litter scoop
Daily scooping helps prevent litter box avoidance.
- ☐ Unscented cat litter
Many cats prefer unscented, fine-textured litter.
- ☐ Food and water bowls
Keep them away from the litter box.
- ☐ Carrier
Needed for transport and emergency evacuation.
- ☐ Bed or washable blanket
A familiar resting spot can reduce stress.
- ☐ Scratching post or pad
Choose a stable post at least about 3 feet high when possible.
- ☐ Hiding spot or covered bed
A cardboard box works too.
Food and daily care
- ☐ Life-stage appropriate cat food
Try to continue the current diet for several days before making changes.
- ☐ Treats
Useful for positive reinforcement and bonding.
- ☐ Brush or comb
Especially helpful for medium- and long-haired cats.
- ☐ Nail trimmers
Trim every 2 to 3 weeks if your cat tolerates it.
- ☐ Enrichment toys
Rotate toys to prevent boredom.
Safety and household prep
- ☐ ID tag or breakaway collar if appropriate
Use only cat-safe breakaway collars.
- ☐ Cord covers or pet-proofing supplies
Protect electrical cords, strings, and small swallowable items.
- ☐ Enzyme cleaner for accidents
Helpful if stress-related accidents happen.
Early veterinary care
- ☐ Initial wellness exam
Schedule within the first week if records are incomplete or concerns arise.
- ☐ Core vaccines if due
Your vet will tailor recommendations to age, history, and risk.
- ☐ FeLV/FIV testing when indicated
Often discussed for cats with unknown history or exposure risk.
- ☐ Fecal parasite test and deworming if needed
Common for kittens and newly adopted cats.
- ☐ Microchip
Some shelters include this already.
- ☐ Spay or neuter if not already done
Range varies widely by region, clinic type, and sex.
Day 1: Keep things small and quiet
Bring your cat directly to a prepared starter room and open the carrier when the room is calm. Let your cat come out on their own. Avoid forcing contact, bathing, or introducing the whole house right away. A hiding cat is often a stressed cat, not a stubborn one.
Show the litter box location, then step back. Offer a small meal and fresh water. If your cat does not eat right away, that can be normal for the first several hours. Keep lights, noise, visitors, and handling to a minimum.
Day 2: Watch appetite, litter box use, and body language
By the second day, many cats begin exploring more at night and resting during the day. Count what your cat eats, note whether they urinate and pass stool, and look for stress signals like flattened ears, crouching, hiding, or hissing. Gentle talking, slow blinking, and sitting quietly nearby can help.
If your cat still has not eaten by the 24-hour mark, contact your vet. Also call promptly for repeated vomiting, diarrhea, open-mouth breathing, or straining in the litter box.
Day 3: Start a routine
Cats do best with predictability. Feed on a schedule, scoop the litter box at least daily, and offer short play sessions with a wand toy if your cat seems interested. Keep interactions brief and positive. Let your cat choose whether to approach.
If you plan to change foods, do not rush it during the first few days unless your vet recommends otherwise. Sudden diet changes can add digestive upset to an already stressful transition.
Day 4: Expand space slowly
If your cat is eating, using the litter box, and moving around the starter room comfortably, you can begin supervised access to one additional area. Keep the starter room available as a safe retreat. In multi-cat homes, continue separation until your vet has reviewed the newcomer and you have a gradual introduction plan.
Add vertical space, scratching options, and hiding spots as your cat explores. This helps reduce stress and gives your cat more control over the environment.
Day 5: Plan the first vet visit
Use this point in the week to organize records and schedule care if it has not already happened. Your vet may review vaccine history, discuss FeLV/FIV testing for cats with unknown backgrounds, check for parasites, confirm microchip status, and talk through spay/neuter timing if needed.
Bring any adoption paperwork, previous vaccine records, medications, and a stool sample if your vet requests one. If your cat is very fearful in the carrier, ask ahead about low-stress handling tips.
Day 6: Build trust, not pressure
Trust grows through choice. Offer treats, play, and calm companionship, but avoid chasing, cornering, or prolonged holding. Many first-time cat parents worry that a shy cat does not like them. In reality, giving space is often what helps the bond form.
If children live in the home, teach them to let the cat rest, avoid grabbing, and watch for signs that the cat wants distance.
Day 7: Reassess what is normal for your cat
At the end of the first week, ask yourself a few practical questions. Is your cat eating reliably? Using the litter box? Grooming? Exploring? Sleeping in relaxed positions? Showing interest in toys or attention? Improvement matters more than instant confidence.
If your cat is still hiding most of the time but is eating, drinking, and using the litter box, that can still fall within a normal adjustment period. If you are seeing poor appetite, weight loss, coughing, sneezing with lethargy, litter box straining, or major behavior changes, it is time to check in with your vet.
Red flags during the first week
See your vet immediately for open-mouth breathing, severe lethargy, collapse, repeated vomiting, inability to urinate, or straining in the litter box with little or no urine produced. These can be emergencies.
Call your vet the same day for not eating for 24 hours, diarrhea lasting more than a day, eye or nose discharge with low energy, or sudden changes in drinking, urination, or behavior.

Questions to Ask Your Vet
Bring these questions to your vet appointment to get the most out of your visit.
- Based on my cat’s age and history, which vaccines are due now and which can wait?
- Does my new cat need FeLV/FIV testing, fecal testing, or deworming based on where they came from?
- Is my cat’s current food appropriate for their life stage, and how should I transition diets if I want to change it?
- What litter box setup do you recommend for my home, especially if I have more than one cat?
- What early signs of stress, upper respiratory infection, or urinary trouble should I watch for this month?
- Is my cat already microchipped, and if so, how do I confirm the registration is updated?
- If my cat gets very stressed in the carrier or car, what low-stress handling options do you recommend?
- If my cat is not yet spayed or neutered, what timing makes sense for their age, health, and home situation?
Frequently Asked Questions
Is it normal for a new cat to hide all day?
Yes. Hiding is common during the first days in a new home. Many cats need a quiet room, predictable routine, and time to approach on their own terms. If your cat is hiding but still eating, drinking, and using the litter box, that can be part of a normal adjustment.
How long can a new cat go without eating?
A few missed meals can happen with stress, but a cat that has not eaten for 24 hours should be seen by your vet promptly. Cats are not built to fast for long, and poor appetite can become serious.
Should I let my new cat roam the whole house right away?
Usually no. Starting with one room helps most cats feel safer and makes it easier for you to monitor appetite, litter box use, and behavior. You can expand access gradually as your cat relaxes.
Where should I put the food and water bowls?
Keep food and water in a quiet area away from the litter box. Many cats prefer separation between eating, drinking, and toileting areas.
How many litter boxes do I need?
A common recommendation is one litter box per cat plus one extra. Even in a one-cat home, having a second box can help during the adjustment period.
When should I schedule the first vet visit?
Within the first week is a smart goal for many newly adopted cats, especially if records are incomplete, your cat has an unknown history, or you have concerns about appetite, sneezing, parasites, vaccines, or behavior.
