Kitten checklists tend to run long, and most of the length is things you will want eventually rather than things you need on day one. A kitten arriving into a home with six items covered is fine. A kitten arriving into a home with a beautiful cat tree and no litter box is not.
The genuinely urgent list is short, and it is worth separating from the pleasant additions so the first week is not spent making emergency trips. Our guide to choosing cat gear covers the wider category.
The Day One List at a Glance
| Item | Why it is urgent | Notes |
|---|---|---|
| Litter box and litter | Needed within minutes | Low sides for small legs |
| Kitten food | Different from adult food | Match what the breeder or shelter used |
| Food and water bowls | Needed immediately | Shallow and stable |
| Carrier | Needed for the journey home | Also the first vet visit |
| Somewhere to sleep | First night matters | A box and a blanket works |
| A scratching surface | Habits form early | Cheaper than replacing a sofa |
The short version: litter, food, bowls, carrier, bedding, and something to scratch. Everything else can arrive in week two.
How We Picked
Items are grouped by when they are actually needed rather than by category, since the failure people describe is not owning the wrong thing but owning the right thing a week late. Kitten-specific sizing carries weight throughout, because adult cat gear frequently does not suit a small animal.
Selections reflect construction and documented features. Descriptions come from product research rather than from personal use.
1. A Low-Sided Litter Box, Best First Purchase
Why It Stands Out
Kittens cannot climb into a standard box reliably, and a box they cannot enter produces accidents that then become habits somewhere else in the house.
Low entry solves that completely, and the box is cheap enough that replacing it with a full-size one later is not a real cost.
Worth Knowing
Low sides mean litter gets kicked out, so a mat underneath is close to essential.
They are outgrown within months rather than years. Our roundup of low-entry litter boxes covers the same design for older cats.
This suits every kitten. Skip it only if you already have a very shallow box.
2. Kitten-Formula Food, Best Nutritional Fit
Why It Stands Out
Kitten food is formulated for growth rather than maintenance, with different protein, fat, and mineral levels than adult food. It is not a marketing distinction.
Buying the same brand the shelter or breeder used avoids a diet change on top of everything else changing at once.
Worth Knowing
Switching foods abruptly commonly causes digestive upset, so any change should be gradual over several days.
Kittens stay on kitten food for around a year, though the timing varies by breed and by vet advice. Our roundup of kitten food covers the options.
This suits every kitten. Skip adult food entirely at this stage.
3. Shallow Stable Bowls, Best Everyday Item
Why It Stands Out
Deep bowls press against a cat’s whiskers, which many cats dislike enough to eat awkwardly or leave food behind. Shallow and wide avoids the issue from the start.
A weighted or wide base stops a kitten pushing the bowl across the floor, which they will otherwise do enthusiastically.
Worth Knowing
Plastic scratches and holds bacteria over time; ceramic and stainless clean better.
Separate food and water bowls placed apart suits cats better than a combined unit. Our roundup of bowls for whisker fatigue covers the shape question.
This suits every home. Skip combined double bowls if you can.
4. A Hard-Sided Carrier, Best for Vet Trips
Why It Stands Out
The carrier is needed for the journey home and then repeatedly for vaccinations, which in the first months means several trips.
Hard-sided carriers with a removable top let a nervous cat be examined without being pulled out, which vets generally prefer.
Worth Knowing
Buying an adult-sized carrier immediately avoids replacing it, since a kitten in a large carrier is fine with a towel for security.
Leaving the carrier out as furniture stops it becoming a vet-only object that triggers hiding. Our roundup of carriers for vet visits covers the designs.
This suits every cat. Skip soft carriers if your cat resists handling.
5. A Scratching Post or Pad, Best Habit Former
Why It Stands Out
Scratching is not optional behavior, and where a kitten learns to do it tends to be where they continue doing it. Providing a surface before the sofa becomes the default is far easier than correcting later.
Sisal is generally more attractive to cats than carpet, and a post needs to be tall enough for a full stretch as they grow.
Worth Knowing
A post that wobbles gets abandoned, and a kitten-sized one is outgrown quickly. A stable full-height post from the start avoids both.
Some cats prefer horizontal pads to vertical posts. Our note on stopping furniture scratching covers redirecting.
This suits every home with furniture. Skip small unstable posts.
6. Wand and Interactive Toys, Best for Development
Why It Stands Out
Wand toys let you play with a kitten without hands becoming the toy, which matters because a kitten that learns to bite hands becomes an adult cat that bites hands.
Interactive play also burns the energy that otherwise goes into climbing curtains at midnight.
Worth Knowing
Wand toys with string should be put away between sessions, since swallowed string is a genuine emergency rather than a minor risk.
Small parts and loose feathers come off and get eaten. Our roundup of cat wand toys covers the category.
This suits every kitten. Skip anything with detachable small parts left unsupervised.
Week Two and Beyond
Once the essentials are covered, the next tier is genuinely useful rather than urgent. A cat tree or window perch gives vertical space, which indoor cats use more than owners expect.
Grooming tools matter earlier for long-haired kittens than short-haired ones, and starting while they are small makes handling easier for life.
Nail clippers belong in this tier too. Getting a kitten used to having paws touched, well before the first trim, makes the whole thing considerably easier later.
Our roundup of cat trees for small apartments covers the vertical space question.
What You Do Not Need Yet
An automatic litter box
Kittens should be monitored, and watching litter box output is one of the ways problems get spotted early. These also frighten some small cats.
A harness and lead
Outdoor access before vaccinations are complete is a separate question, and harness training suits a settled cat rather than a newly arrived one.
A large cat condo
Useful later, and a small kitten uses a fraction of it. Buying once when they are grown avoids buying twice.
Most supplements
A complete kitten food covers nutritional needs for a healthy kitten, and additions should follow a vet conversation rather than precede one. Our roundup of cat vitamins covers when they apply.
Setting Up Before Arrival
Prepare one room rather than the whole house. A single space with litter, food, water, a bed, and a hiding place is less overwhelming than free run of everywhere, and it makes the first days considerably calmer.
Place the litter box away from food and water, since cats generally avoid eliminating near where they eat.
Have a hiding place available. A cardboard box on its side is genuinely as good as anything sold for the purpose, and a kitten with somewhere to retreat settles faster than one without.
Our note on cat beds for indoor cats covers making the space safe.
What to Look For
Kitten-appropriate sizing
Litter boxes and beds need to suit a small animal now. Carriers and scratching posts are better bought at adult size immediately.
Stability
Bowls that slide and posts that wobble both get abandoned. Weight and a wide base matter more than appearance.
Cleanability
Everything a kitten uses gets dirty. Machine-washable bedding and dishwasher-safe bowls save a lot of effort.
Safety of small parts
Anything that can detach can be swallowed. String, feathers, and bells all warrant supervision.
Common Mistakes to Avoid
Buying adult-sized litter boxes
A kitten that cannot climb in will go elsewhere, and elsewhere becomes a habit that outlasts the box.
Changing food immediately
Diet changes on arrival day stack digestive upset on top of the stress of moving. Match what they were eating, then transition slowly.
Leaving string toys out
Swallowed string causes serious internal injury. Wand toys are for supervised sessions and should be stored between them.
Giving the run of the house on day one
A single prepared room helps a kitten settle faster than an entire house does. Our note on introducing a new cat covers expanding their territory.

Kitten Supplies FAQ
What do I absolutely need on day one?
A litter box with low sides, kitten food, shallow bowls, a carrier, somewhere to sleep, and a scratching surface. That covers the first days, and everything else on a typical checklist can wait a week or two.
Do kittens need special food?
Yes. Kitten formulations are built for growth rather than maintenance, with different protein, fat, and mineral levels. Adult food does not meet those requirements during the first year.
What size litter box should I get?
One with low sides a kitten can actually climb into. A box they cannot enter leads to accidents elsewhere, and those spots become habits that persist after they have grown.
Should I buy a kitten-sized carrier?
Buy adult size straight away. A kitten in a larger carrier is fine with a towel for security, and it saves buying twice within the year.
How many litter boxes do I need?
The common guidance is one per cat plus one spare, so a single kitten suits two boxes. It matters more in multi-cat homes and with cats that are particular about cleanliness.
Are scratching posts really necessary?
Scratching is normal behavior rather than a bad habit, so the question is where it happens rather than whether it does. Providing a stable post early is far easier than redirecting an established preference for the sofa.
What toys are safe to leave out?
Solid toys without detachable parts. Anything with string, feathers, or small attachments should be used during supervised play and put away afterward, since swallowed string is a serious emergency.
What can wait until later?
Automatic litter boxes, harnesses, large cat furniture, and most supplements. A cat tree and grooming tools are worth adding within the first weeks, and none of them are needed on arrival day.
