Domestic Shorthair Kitten
New kitten setup guide — everything your domestic shorthair needs from day one
Domestic shorthair kittens are the most common cats in the world — resilient, adaptable, and variable in personality. Bringing one home is simpler than bringing home a puppy, but there's still more to set up than most people anticipate. Getting the basics right in the first week prevents the problems (litter box aversion, furniture scratching, hiding) that cause cats to be surrendered.
What ships in the box
If you're adopting from a shelter, you'll typically receive basic health records, vaccination history, and sometimes a small bag of the food they've been eating. Breeders may include a comfort item with the mother's scent. Everything else is yours to source.
Litter box setup
The rule for litter boxes is one per cat, plus one extra. For a single kitten, that means two boxes. Box placement matters as much as box count: put them in quiet, low-traffic areas where the kitten can use them without feeling trapped or startled. Never put the litter box near food and water. Use unscented, clumping clay or fine-grain litter — most cats strongly prefer fine, unscented litter. Scoop daily and fully change the litter every 1–2 weeks. Kittens have small bladders and use the box frequently; a dirty box is a major cause of litter box aversion, which is very difficult to reverse once established.
Scratching: protect your furniture
Cats scratch to maintain claw health, mark territory, and stretch. This is a biological need, not a behavioral problem — and declawing is now widely recognized as harmful and is illegal in many countries. The solution is providing appropriate scratching surfaces that are more appealing than your furniture. Cats prefer tall, sturdy vertical surfaces and stable horizontal surfaces. A 32–36 inch sisal rope post that doesn't wobble is essential; most cheap cat trees are too short and too unstable to be satisfying. Place scratching posts near furniture your kitten has already targeted, and reward use with treats or play. Double-sided tape on targeted furniture corners discourages scratching there temporarily while you redirect.
Kitten nutrition
Kittens need kitten-specific food — not adult cat food — until 12 months. Kitten formulas have higher protein, fat, and caloric density to support rapid growth. Wet food provides hydration and is closer to a cat's natural diet; aim for at least one wet meal per day. For dry food, look for a named protein (chicken, salmon) as the first ingredient. Avoid foods with excessive plant-based proteins, artificial colors, or corn syrup. Free-feeding dry food is common and convenient, but can lead to obesity; many vets now recommend portioned meals twice daily even for kittens after 3 months.
Vertical space and enrichment
Cats are vertical animals. In the wild, height provides safety, vantage points for hunting, and territory. A kitten without access to vertical space is a stressed kitten. A cat tree in a window with a bird or squirrel view is one of the highest-value environmental enrichments you can provide. Wall-mounted shelves and perches extend vertical territory without consuming floor space. Interactive play with a wand toy for 10–15 minutes twice daily is essential — it satisfies the hunting drive that, if unmet, turns into 3am zoomies or aggressive play biting. Puzzle feeders convert mealtime into enrichment.
Vet essentials
Schedule a vet visit within the first week of bringing your kitten home, regardless of their vaccination status. A vet will confirm health, check for parasites, establish a vaccine schedule, and advise on spay/neuter timing (typically 4–6 months). Kittens need a series of FVRCP vaccines (feline distemper, rhinotracheitis, calicivirus) every 3–4 weeks until 16 weeks of age, plus a rabies vaccine. Monthly flea and heartworm prevention is strongly recommended even for indoor cats — fleas hitch rides on clothing and shoes. Set up a dedicated carrier before the vet visit: leave it open in the living space so the kitten associates it with sleeping, not just vet trips.
Frequently asked questions
How many litter boxes does a kitten need?
Two boxes for a single kitten — one per cat plus one. This prevents one box from becoming too soiled before you can scoop, and gives the kitten an option if they're startled at one location. Add an additional box for each additional cat in the household.
What litter is best for kittens?
Fine-grain, unscented, clumping clay litter is the most widely accepted by cats. Avoid scented litters (cats dislike strong fragrances and have much more sensitive noses than humans), pellet litters for young kittens (they don't dig well in pellets), and crystal litters until the kitten is older. Once you find a litter your cat accepts, don't switch — litter changes are a common trigger for litter box aversion.
When should I switch my kitten to adult cat food?
At 12 months for domestic shorthairs. Transition gradually over 7–10 days by mixing increasing proportions of adult food with the kitten food. If you're feeding a kitten food labeled 'for all life stages,' you can continue using it, but a proper adult formula is generally preferable for cats over one year.
Do indoor kittens need flea prevention?
Yes. Fleas enter homes on human clothing and shoes. An indoor cat can absolutely get fleas without ever going outside. Monthly topical prevention (Revolution Plus or Advantage Multi) is the most effective approach and also covers ear mites and heartworm. Revolution Plus requires a vet prescription; Advantage Multi is a popular OTC alternative for flea-only coverage.
How do I stop my kitten from scratching furniture?
Provide at least two appropriate scratching surfaces before your kitten arrives — a tall, stable sisal rope post and a horizontal cardboard scratcher cover most cats' preferences. Place them next to furniture the kitten has already targeted. Apply double-sided tape or aluminum foil to targeted furniture areas temporarily while redirecting. Reward the kitten with treats immediately when they use the post. Never punish scratching — it won't stop the behavior and damages trust. Soft plastic nail caps (Soft Paws) applied every 4–6 weeks are a humane alternative for persistent cases.
What vaccinations does a kitten need?
Core vaccinations for kittens include the FVRCP series (feline viral rhinotracheitis, calicivirus, and panleukopenia) starting at 6–8 weeks and repeated every 3–4 weeks until 16 weeks old. A rabies vaccine is required in most states, typically given at 12–16 weeks. Non-core vaccines (FeLV for cats with outdoor access, FIV in high-risk areas) are given based on lifestyle. Kittens acquired before completing their series need vet confirmation of vaccination history and completion of the remaining doses.
How do I litter train a kitten?
Most kittens instinctively use a litter box without training — the instinct to dig and cover waste is hardwired. Place your kitten in the litter box after meals, after naps, and after play sessions. Use fine-grain unscented clumping litter, which most cats strongly prefer. If accidents occur outside the box, clean thoroughly with enzymatic cleaner (Nature's Miracle) to eliminate the scent marker that encourages repeat soiling in the same spot. The most common cause of litter box avoidance is a dirty box — scoop daily.
Pro tip
Set up the litter box, food, water, and a small safe room before you bring your kitten home — not a whole apartment, just one room. New environments are overwhelming for kittens. Starting them in a single room lets them establish their core territory before expanding. Most kittens are comfortable enough to explore the full home within 3–7 days when introduced this way. Rushing this process leads to hiding, litter box misses outside the box, and a much longer adjustment period.
