# Cat's First Day Home: Helping a New Cat Settle In Your cat's first day home should be quiet and small. Set your new cat up in one closed room with food, water, a litter box, bedding, and a hiding spot, then let the cat set the pace [1]. Most cats need a few days or more to settle in, and hiding on day one is normal [1]. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Confine your new cat to one small, quiet room with the door closed, and keep other pets away from the carrier [1][2]. - Put everything the cat needs in that room: comfy bedding, hiding spots, toys, food, water, a scratcher, and a litter box [1]. - Sit a few feet away and let the cat come to you. Do not pull the cat out of hiding [1]. - Expect hiding, and expect it to last. Some cats settle in within hours, but most need a few days or more [1]. - Move to the next step only when the cat moves around the room confidently, eats well, and uses the litter box [1][2]. ## Your Cat's First Day Home: A Room-by-Room Plan Think of day one as a quiet landing, not a home tour. Cats can be easily overwhelmed by new spaces, so the goal is to shrink your whole house down to one safe room [1]. Everything else can wait. ### Before the cat comes inside Set up the safe room before you bring the carrier through the door. Have the litter box filled, water fresh, food measured, and a hiding spot ready. If you have a resident cat, confine that cat to a different room first so the two cats cannot see each other, and do not let your resident cat approach the new cat in the carrier. That first look can be extremely frightening for a cat who just left everything familiar [2]. ### The safe room Pick a small room with a door that closes, such as a bathroom, bedroom, or laundry room. Small is the point. A whole house gives a nervous cat too many places to worry about. Inside the room, provide: - A litter box in a quiet corner, away from the food and water - Food and water in separate spots - Comfy bedding - At least one hiding spot, such as a covered bed or a box on its side - A scratcher - A few toys That full list comes straight from feline welfare guidance for new cats [1]. If you want the longer version of this process, including how to widen your cat's world over the following weeks, see [How To Introduce New Cat To Home](/knowledge/veterinary-medicine/clinical-methods/how-to-introduce-new-cat-to-home). ### The rest of the house Close the door and leave the rest of the house off limits for now. When your cat moves around the safe room confidently, you can begin slowly introducing the rest of your home [1]. That might be later today, or it might be next week. Both are normal. ### If you have other pets Keep the new cat and your resident cat separated, and do not rush a face-to-face meeting. The first impression matters, and aggression during a first meeting can set the tone for the whole relationship [2]. If your resident cat has lived peacefully with cats before, the odds are good that she will adjust, but no one can predict how any two cats will get along [2]. Patience is the whole strategy [2]. For the step-by-step version, read [Introducing A New Cat To A Cat](/knowledge/veterinary-medicine/clinical-methods/introducing-a-new-cat-to-a-cat) and [Introducing A New Cat To Existing Cat](/knowledge/veterinary-medicine/clinical-methods/introducing-a-new-cat-to-existing-cat). ### How to interact on day one Sit a few feet away from your cat and let the cat approach you for petting or attention [1]. That is the whole rule. Forced handling backfires. In one study of owner-cat interactions, passive interactions were linked to increased oxytocin and decreased cortisol in cats, while forced interactions showed the opposite pattern [3]. In plain terms, let the cat choose. ## Cat First Day Home Schedule and Checklist Use this as a loose template, not a stopwatch. Your cat's comfort level sets the pace. | Time | What to do | |---|---| | Before arrival | Set up the safe room. Confine resident pets to another room [2]. | | Arrival | Carry the carrier into the safe room, close the door, open the carrier, and step back. Let the cat exit on its own. | | First hour | Stay quiet nearby. No grabbing, no passing the cat around to family members. | | First few hours | Offer food, water, and a clean litter box. Sit a few feet away and let the cat come to you [1]. | | Evening | Keep the room dim and calm. Check that the cat has eaten, drunk, and used the box. | | Overnight | Leave the cat in the safe room with the door closed. Expect some hiding and some nighttime activity. | | Day 2 and beyond | Repeat. When the cat moves around the room confidently, start slow introductions to the rest of the home [1]. | ### Day-one checklist - Litter box set up in a quiet spot, with about one to two inches of unscented litter [1] - Food and water available - Hiding spot available - Scratcher available - Door closed - Resident pets separated - A quiet place for you to sit and wait ## Cat First Day Home Hiding: What Is Normal Hiding on day one is expected. A new cat in a new house is in an unfamiliar space with unfamiliar smells, and hiding is how cats cope with that. Set up hiding spots on purpose, because they are part of the basic setup for a new cat [1]. Some cats settle in within a few hours, but most need a few days or more [1]. So a cat who spends day one under the bed is not necessarily in trouble. A cat who is still hiding a week later, or who is hiding and not eating, is a different story. One thing to know about cats in general: they often manage conflict and stress by avoiding each other and by using vertical space. In a study of cats in a shared environment, cats preferred elevated structures and cat-only rooms, especially when the space was busy, and cat-cat interactions were infrequent [4]. Your cat's urge to get up high or tuck away is normal feline behavior, not a sign of a broken cat. Give your cat hiding places that are safe and easy to reach. A box on its side, a covered bed, or a quiet closet corner all work. Do not drag your cat out of a hiding spot to force interaction. Sit nearby and talk softly instead [1]. ## Signs Something Is Wrong Hiding is normal. Hiding plus any of the following is not. - Not eating or drinking for more than 24 hours - Not using the litter box, or straining to urinate - Vomiting or diarrhea that keeps going - Labored breathing, open-mouth breathing, or constant panting - Crying out, pacing, or restlessness that does not settle - Hiding that gets worse over days instead of better - Any cat who was just adopted with a known health problem If you adopted a cat with health problems, that cat needs to be seen by a veterinarian as soon as possible [5]. Do not wait for a settle-in period to pass. Behavior can also be a clue. In a study of indoor and outdoor cats, cats showing isolation and excessive vocalization had higher hair cortisol levels, a marker of longer-term stress [6]. That does not mean every hiding cat is stressed, but a cat who withdraws and vocalizes a lot is telling you something. ## Common Mistakes on Day One **Letting the cat roam the whole house right away.** Cats can be easily overwhelmed by new spaces [1]. Start small and expand later. **Inviting a crowd.** A quiet room means a quiet room. Too many people, too much noise, and too much handling all work against you. **Forcing interaction.** Let the cat approach you [1]. Forced handling is linked to a stress response in cats, while passive, cat-led contact is linked to a calmer one [3]. **Rushing the introduction to other pets.** The first meeting between cats matters, and a bad one can shape their relationship going forward [2]. Slow beats fast every time. **Skipping the vet visit.** A newly adopted cat with health problems needs to be seen as soon as possible [5]. Even a seemingly healthy new cat needs a checkup soon after adoption, and your veterinarian will set the timing. **Skipping basic supplies.** Before your cat comes home, have the basics ready: a litter box, food, and ideally a scratching post [5]. ## Supplies and Setup That Matter for Health The setup is not decoration. It is the foundation for eating, drinking, and litter box use, which are the three things you will track most closely on day one. ### Litter box Most cats do best with a large, uncovered litter box [1]. For kittens or senior cats, choose a box with lower sides for easy access [1]. Most cats prefer about one to two inches of unscented litter [1]. Place the box in a quiet area, scoop twice a day, and do a full clean at least once a month with mild dish soap or a pet-friendly enzymatic cleaner. Avoid bleach and other harsh chemicals [1]. ### Food and water Keep food and water away from the litter box. Offer the food your cat was already eating if you know it, and change foods gradually if you plan to switch. Your veterinarian can help you choose a diet based on your cat's age and health. ### Hiding spots and vertical space Provide hiding spots and, when your cat is ready to explore more of the home, vertical options like cat trees or shelves. Elevated structures matter to cats, especially in busier spaces [4]. ### Scratching post A scratching post is part of the basic setup for a new cat [5]. Put it near where your cat rests. ### Carrier Leave the carrier in the safe room with the door open or removed. It becomes a familiar bed instead of a scary box, which makes future vet visits easier. If your cat seems stressed at the clinic, ask whether your veterinary practice offers feline-only waiting areas or hours. In one survey, owners at clinics without feline-segregated areas reported more difficulty getting cats out of carriers and more difficulty giving medication at home [7]. ### Pheromones and calming products These are commonly used, but the evidence for any specific product is not well established in veterinary research. Ask your veterinarian what they recommend for your cat. ## Limitations and When to Contact a Veterinarian This plan covers a normal, healthy cat settling into a new home. It cannot tell you whether your individual cat is sick, and individual cases need a veterinarian. Call your veterinary clinic for guidance about your cat specifically. **Contact a veterinarian the same day if:** - Your cat has not eaten or drunk in more than 24 hours - Your cat has not used the litter box in more than 24 hours - Your cat is hiding and also vomiting, having diarrhea, or acting painful - Your cat was adopted with a known medical condition [5] **Go to an emergency clinic now if:** - Your cat is straining to urinate with little or no urine coming out, especially a male cat - Your cat is breathing with an open mouth, breathing hard, or panting - Your cat is collapsed, unresponsive, or having a seizure - Your cat has swallowed something potentially toxic If you suspect poisoning, contact the ASPCA Animal Poison Control Center at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661 right away. **Schedule a routine visit soon after adoption if:** - Your cat is eating, drinking, and using the litter box normally - Your cat seems healthy but has never had a checkup with you - You need guidance on vaccines, parasite prevention, diet, or spay/neuter timing Your veterinarian sets all of that for your cat based on age, weight, and health history. ## Frequently Asked Questions ### Should I let my new cat hide on the first day? Yes. Hiding is a normal response to a new space, and hiding spots are part of the recommended setup for a new cat [1]. Give your cat a quiet room, a place to tuck away, and time. Do not pull the cat out. ### How long does it take a cat to adjust to a new home? It varies. Some cats settle in within a few hours, but most need a few days or more [1]. Move at your cat's pace, and expand access to the rest of the home only when your cat is moving around the safe room confidently [1]. ### Should I keep my new cat in one room on the first day? Yes. A small, quiet room with the door closed is the standard first step, with bedding, hiding spots, toys, food, water, a scratcher, and a litter box inside [1]. This keeps your cat from being overwhelmed and keeps other pets separated [2]. ### What if my new cat will not eat on the first day? A skipped meal on day one can happen, but not eating for more than 24 hours is a reason to call your veterinarian the same day. Cats who stop eating can get sick quickly. Track how much your cat eats and drinks so you can report it accurately. ### When can I introduce my new cat to my other cat? Only after your new cat is eating well, using the litter box, and exploring confidently, and only if your resident cat is not showing signs of stress [2]. At that point you can start with scent swapping by switching the cats' locations [2]. Keep every step gradual, because the first impression between two cats matters [2]. ## Related Articles - [How To Introduce New Cat To Home](/knowledge/veterinary-medicine/clinical-methods/how-to-introduce-new-cat-to-home) - [Introducing A New Cat To A Cat](/knowledge/veterinary-medicine/clinical-methods/introducing-a-new-cat-to-a-cat) - [Introducing A New Cat To Existing Cat](/knowledge/veterinary-medicine/clinical-methods/introducing-a-new-cat-to-existing-cat) - [How To Introduce New Cat To Cat](/knowledge/veterinary-medicine/clinical-methods/how-to-introduce-new-cat-to-cat) - [How To Introduce A New Cat](/knowledge/veterinary-medicine/clinical-methods/how-to-introduce-a-new-cat) - [How Do You Introduce A New Cat To Your Cats](/knowledge/veterinary-medicine/clinical-methods/how-do-you-introduce-a-new-cat-to-your-cats) - [Cat Not Adjusting to a New Home: How to Help](/knowledge/veterinary-medicine/behavior/cat-not-adjusting-new-home) - [How to Calm a Cat Down: Stress Triggers and Settling Techniques](/knowledge/veterinary-medicine/anxiety-and-behavior-support/how-to-calm-a-cat-down) - [Cat Not Adjusting to a New Kitten: Steps That Work](/knowledge/veterinary-medicine/behavior/cat-not-adjusting-new-kitten) ## References 1.
