First Week Do's and Don'ts

| Let kitten hide — it's normal and reduces stress | |
| Use Feliway diffuser to create calming environment | |
| Handle kitten gently during calm moments — paws, ears, mouth | |
| Schedule vet visit within the first week | |
| Force kitten out of hiding spots or chase them | |
| Introduce to all family members and pets on day one | |
| Skip kitten-proofing — kittens explore everything with their mouth |
The 'safe room' is the single most important setup for a new kitten. A small, quiet space (bathroom or spare bedroom) with all essentials lets the kitten decompress. Most behavior problems in adult cats trace back to overwhelming first-week experiences.
Kittens can develop serious health issues quickly. Lethargy, not eating for 12+ hours, diarrhea, vomiting, or eye/nose discharge warrant an immediate vet visit. Young kittens have limited reserves and can decline rapidly.
A new kitten does best starting in one small, quiet room with a litter box, food, water, and a hiding spot, then gradually expanding to the rest of the house over the first week or two rather than getting free run of the whole home on day one. Schedule the first vet visit for within that first week home if it hasn't already happened, since kittens are commonly dewormed starting as early as 3 weeks old and vaccinated starting around 6 weeks, with follow-up boosters continuing every few weeks after that.
The first week home
A kitten's whole world just changed size; a slow introduction is what makes it feel safe

Have this ready before the kitten arrives
A kitten who spent its entire short life in one small space can find an average living room genuinely overwhelming, not exciting. What looks to us like a fun new home can register to a kitten as a huge, echoing, unfamiliar space with no safe corner yet.
Getting the first week right matters because it shapes how confident and secure this cat feels in your home for years, not just days. A kitten that's rushed into unfamiliar territory too fast can become a cat who hides under the bed for months; one given a gradual, controlled introduction usually settles in far faster.
One Small Room Beats the Whole House on Day One
Set up a single quiet room, a spare bedroom or bathroom works fine, with a litter box, food and water bowls kept away from each other, and at least one spot the kitten can hide completely, a covered bed or an open box turned on its side. Confining a new kitten to one room isn't a punishment, it's what lets a small animal in a strange place feel like it has full control over a manageable amount of territory, which is the fastest route to actual confidence.
Expect some hiding and a smaller appetite than usual in the first day or two. That's a normal adjustment response, not necessarily a sign anything is wrong, as long as the kitten is still using the litter box and drinking water.
Expansion Happens in Days, Not Hours
Once the kitten is using the litter box confidently and seeking out attention rather than only hiding, usually within a day or two, short supervised visits to one additional room at a time work well. Let the kitten set the pace: a kitten that bolts back to the safe room is telling you it needs another day before the next expansion.
By the end of the first week or two, most kittens are comfortable exploring pet-safe areas of the home and have settled into a predictable daily rhythm around feeding and play.
The First Vet Visit Belongs in This Same Week
If the kitten hasn't already had a veterinary exam, the first week home is exactly when to schedule one. Kittens are commonly dewormed as early as 3 weeks of age, with repeat treatment continuing every couple of weeks until about 8 to 9 weeks old and then monthly through 6 months, and the first vaccination round typically isn't given before 6 weeks of age, continuing every 3 to 4 weeks until at least 16 weeks. Your vet will confirm exactly where in that schedule your specific kitten already stands.
A kitten's confidence in week one is built in inches, not leaps, and every quiet, boring day spent in that first small room is doing more work than it looks like from the outside.
The 2021 AAHA/AAFP Feline Life Stage Guidelines recommend scheduling a kitten's first veterinary visit during the first week home, note that kittens can be dewormed as early as 3 weeks of age with repeat treatment continuing every two weeks until 8 to 9 weeks old and then monthly until at least 6 months, and that the first vaccination round is generally given no earlier than 6 weeks of age, continuing every 3 to 4 weeks until at least 16 weeks.
