The first night with a new cat is mostly about doing less. Put your cat in one quiet, prepared room, give them food, water, a litter box and somewhere to hide, and then leave them alone. Most of the work is resisting the urge to cuddle them.
Here’s how to set it up, what’s normal, and what isn’t.
What to Do Before You Bring Them Home
Set up a “base room” before the cat arrives. A spare bedroom or bathroom works well. The idea, which is consistent with advice from groups like the AAFP and ISFM on environmental needs, is to let the cat meet a small, safe space before a whole house.
Your base room needs:
- A litter box (see how many litter boxes you actually need), placed away from food and water
- Food and fresh water, in separate spots
- At least one hiding place: a cardboard box on its side, a covered bed, or a cat carrier with the door open
- A scratching surface
- A soft bed or blanket that smells of the shelter or previous home, if you were given one
Check the room for gaps behind appliances, loose cords and anything small enough to be chewed or swallowed. Our room-by-room kitten-proofing checklist applies to adult cats too.
What the First Night Looks Like
Bring your cat home in their carrier, close the door to the base room, then open the carrier and sit quietly nearby, or leave. Let them choose.
Here’s what’s normal:
- Hiding. Under the bed or behind furniture is a very common first reaction.
- Not eating for the first several hours. Stress suppresses appetite in many cats.
- Not using the litter box right away.
- Vocalizing at night. Some cats cry or pace in unfamiliar places.
- Hissing or swatting if you reach in. It means “I’m scared,” not “I’m aggressive.”
Don’t read these as signs you picked the wrong cat. How long adjustment takes varies enormously. Our guides on how long a new cat takes to settle in and what to do when a new cat won’t come out of hiding cover the days that follow.
Should Your New Cat Sleep in Your Bedroom?
It’s tempting, and some cats do settle faster near their person. But a bedroom is only a good base room if it’s safe and quiet. If you have other pets, a cat-proof bedroom is still better than shared space.
A reasonable compromise: put the cat in the base room, sit there for a while in the evening, and decide on bedroom sleepovers after the first week or so, once they’re comfortable.
What to Do (and Not Do) on Night One
Do:
- Speak softly and move slowly
- Leave food, water and the litter box where the cat can reach them without passing you
- Let the cat approach you
- Keep other pets and visitors away for now
- Use a nightlight so the room isn’t pitch dark
Don’t:
- Pull the cat out of a hiding spot
- Hold them to “get them used to you”
- Introduce other pets yet
- Let the cat roam the whole house on night one
- Change food abruptly. If you can, ask the shelter what they were eating and start with that
How Long to Keep Them in One Room
Many people let the cat expand their territory gradually, opening one more room once the cat is eating, using the litter box and coming out to explore. There’s no fixed timetable. See how long to keep a new cat in one room for the signs that it’s time.
If Your Cat Cries at Night
Night crying on the first few nights is common, and it usually fades as the room becomes familiar. A few things that help: a warm, soft bed, a worn T-shirt that smells like you, a predictable evening play session to burn off energy, and a last meal shortly before bed. Try not to reward crying with a big reaction every time. Calm, brief reassurance is fine, and if it continues beyond a week or two, mention it to your vet, since pain, hunger or illness can sometimes be behind it.
When to See a Vet
A shy cat is normal. A sick cat is not. Call your vet if your new cat:
- Doesn’t eat or drink at all for 24 hours (kittens and seniors sooner)
- Has repeated vomiting or diarrhea
- Is sneezing, with eye or nose discharge, or breathing with their mouth open
- Is straining in the litter box or producing no urine
- Seems lethargic rather than just hiding

The Takeaway
Keep night one boring. A small room, the basics and patience will do more than any amount of affection. Let the cat set the pace; the cuddles come later, usually sooner than you’d think.
