New Kitten Guide
Bringing home a kitten is exciting, but the first few months also come with a lot of questions. This guide walks you through supplies, feeding, litter box setup, socialization, preventive care, and the warning signs that mean it is time to call your vet.
What to do before your kitten comes home
A new kitten does best with a calm, predictable setup from day one. Prepare a small starter room with a bed, hiding spot, food and water bowls, toys, a scratching post, and a litter box placed well away from food and water. VCA notes that kittens should have a safe area where they can stay when unsupervised, and cats generally prefer separate zones for eating, resting, and toileting. ASPCA guidance also emphasizes providing an appropriate litter box setup and a sturdy scratching post. Before bringing your kitten home, plan a first veterinary visit, choose a nutritionally complete kitten diet, and gather any records on prior vaccines, parasite control, and previous food. If you already have pets, keep the new kitten separated at first until your veterinarian has examined them.

New kitten checklist
Starter room
Set up one quiet room or enclosed area so your kitten can settle in gradually.
Litter box
Use an easy-to-enter litter box in a low-traffic area, away from food and water.
Kitten food
Choose a complete and balanced diet formulated for kittens and transition foods gradually.
Scratching outlet
Provide a sturdy scratching post to support normal scratching behavior.
Carrier
Leave the carrier out at home so it becomes a familiar, low-stress space.
First vet visit
Book a wellness exam soon after adoption or by 6 to 8 weeks of age if not already done.
Microchip
Discuss microchipping early in case your kitten slips outside or gets lost.
Parasite plan
Ask your vet about deworming, flea control, and parasite screening based on age and lifestyle.
Your kitten’s first veterinary visits
Authoritative veterinary sources agree that kittens need early preventive care. VCA says the first veterinary visit is typically at 6 to 8 weeks of age unless illness is present sooner. Cornell advises that any new cat or kitten should be examined by a veterinarian as soon as possible after coming home, especially if health history is incomplete. At that first visit, your vet may perform a physical exam, discuss vaccination scheduling, check for internal and external parasites, review nutrition, and consider FeLV/FIV testing when history is unknown or household circumstances warrant it. AAHA also highlights screening for congenital concerns, planning the first year of care, and arranging spay or neuter before 5 months old.

Feeding, hydration, and growth in the first year
Kittens need a diet formulated for growth. Cornell recommends feeding a well-balanced, nutritionally complete food appropriate for life stage and continuing the previous diet at first while any transition happens gradually. Sudden food changes can contribute to stomach upset in some kittens, so a slow switch is usually easier on the digestive tract. Fresh water should always be available. If your kitten stops eating, vomits repeatedly, has diarrhea, or seems unusually tired, call your vet rather than trying random home remedies. ASPCA warns that some people foods and even some baby foods can be dangerous, particularly products containing onion or garlic powder.

Vaccines, deworming, and parasite prevention
Kittens are especially vulnerable to infectious disease and parasites. Merck Veterinary Manual explains that maternal immunity fades over time, which is why kittens receive vaccines on a schedule rather than a single shot. Cornell states that the common FVRCP vaccine series generally begins at 6 to 8 weeks of age and is repeated every 3 to 4 weeks until 16 to 20 weeks of age. Rabies vaccination is also recommended and may be legally required, with timing depending on vaccine type and local law. Merck further notes that intestinal parasites are very common in kittens, and veterinarians often treat them routinely with deworming medications and fecal follow-up as needed. External parasites such as fleas, ticks, and mites should also be checked for and prevented based on age, environment, and risk.

Litter box setup and early behavior basics
Many kittens adapt quickly to litter box use when the setup is simple and clean. ASPCA advises regular litter box cleaning and notes that refusal to use the box can sometimes reflect an underlying medical problem, so owners should consult a veterinarian if litter box avoidance develops. ASPCA also notes that trying to force or over-manage litter box use can backfire. Use an easily accessible box, scoop frequently, and avoid placing the box in a noisy area next to food. Along with toileting, provide acceptable scratching outlets from the start. ASPCA recommends a sturdy scratching post at least three feet high. If your kitten suddenly starts urinating outside the box, straining, or vocalizing in the box, call your vet promptly.

Socialization, introductions, and enrichment
Early social experiences shape how confident a kitten becomes. VCA notes that the most sensitive socialization period begins around 2 weeks of age and is especially important through about 7 weeks, though positive socialization should continue throughout kittenhood. When introducing a kitten to a home, go slowly with people, handling, carriers, nail trims, household sounds, and other pets. Cornell recommends separating a new cat from resident cats until veterinary evaluation if health history is uncertain. VCA also suggests making the carrier a positive place by leaving it out with the door open and using food or toys to encourage exploration. For mental and physical wellbeing, offer safe play, climbing options, hiding spaces, and predictable routines.

Signs your kitten may be sick
Not eating
A kitten who stops eating should be assessed promptly because young kittens can decline quickly.
Vomiting or diarrhea
Repeated digestive signs can lead to dehydration and may reflect infection, parasites, or diet issues.
Sneezing with discharge
Nasal congestion or eye discharge may point to an upper respiratory infection and can reduce appetite.
Lethargy
Marked tiredness, weakness, or a sudden drop in playfulness is a reason to call your vet.
Straining in the litter box
Straining, pacing, or crying near the litter box can be an emergency, especially if urine flow is blocked.
Fleas, mites, or worms
Visible parasites, itchy ears, potbelly appearance, or abnormal stool warrant veterinary guidance.
When to see a vet right away
Call your veterinarian promptly if your kitten is not eating, vomits repeatedly, has ongoing diarrhea, seems lethargic, struggles to breathe, or suddenly behaves very differently. AAHA specifically warns that if a young male cat is straining, pacing, and yowling near the litter box, this may reflect a urinary blockage and can become life-threatening quickly. ASPCA advises veterinary attention if signs such as anorexia, vomiting, diarrhea, or lethargy continue, and in kittens it is reasonable to be more cautious because they can dehydrate or worsen faster than adult cats. If you are unsure whether a sign is serious, call your vet.
