The thought of looking after an adorably tiny newborn kitten can be appealing, but it’s actually incredibly hard work! Whether you find yourself helping your cat support her kittens or fostering a kitten that’s been abandoned, these little babies require round-the-clock care to grow up big and strong.

If you’re wondering exactly what’s involved in caring for a newborn kitten, you’re in the right place. Our guide and care sheet will walk you through everything that you need to know. From what to feed them and how to care for them and keep them warm to which illnesses you need to look out for, we’ve got you covered.

What to Consider Before Owning a Newborn Kitten

Before you even think about owning a newborn kitten, you need to be 100% sure that you can meet their needs. There are two main ways that you might find yourself owning a newborn kitten:

  • Your cat has a litter of kittens.
  • You’ve adopted, fostered, or rescued kittens.

If your cat has a litter of kittens, you can expect her to carry out most of the care. But if she rejects some of the kittens, you’ll need to care for them yourself, much as you would for a fostered or rescued kitten.

Newborn kittens don’t offer much in the way of interaction, as for the first 4 weeks, they’re completely dependent on their mother cat (or caregiver!) for everything that they need. They are still high-maintenance, though! For the first 2 weeks, expect to feed them every 3 hours, even overnight. They’ll also need help going to the toilet. Very young kittens can’t regulate their own body temperature, so if there isn’t a mother cat to keep them warm, you may need to keep them in an incubator or under a heat lamp.

If you’re going to be caring for newborn kittens, you need to make sure someone can be home to look after them at all times for the first 12 weeks of their life. They should not be left alone for longer than 20 or so minutes at a time.

Where Can I Get a Newborn Kitten?

If you’re considering buying a kitten from a breeder, these little bundles of fluff won’t be ready to leave their mother cat until they’re at least 8 weeks old. Many breeders prefer to allow kittens to stay with their mothers until they’re at least 12 weeks old. This gives them a better opportunity to learn how to use a litter box and play independently. By 12 weeks, a kitten’s immune system will also be better developed, meaning they stand a much better chance of growing into a healthy and happy adult cat.

You may find yourself looking after newborn kittens if your own cat has had a litter of kittens. She might not produce enough milk for all the kittens, and some cats reject their kittens, in which case you’ll need to care for them instead.

If you’re fostering newborn kittens that have been found without a mother, they may come to you when they’re only a few days old. These little babies usually require the care of an experienced foster human who is well versed in caring for newborn kittens. Speak to a cat rescue organization before attempting to take care of kittens from a feral mother found outside. She may have just left her kittens alone while she went to find food.

What Kind of Home Does My Newborn Kitten Need?

For their tiny size, newborn kittens need a great deal of equipment! If a mother cat is caring for her kittens, she keeps them warm and well-fed and helps them go to the bathroom.

For humans looking after newborn kittens, you’ll need to provide all of that yourself! Here’s a list of everything that you’ll need.

Feeding supplies:
  • Kitten milk replacer
  • Bottles and teats
  • Bottle brush
  • Whisk
  • Funnel
  • Kitchen scales
  • Bottle sterilizer
  • Kitten food
  • Shallow food and water bowls
Living area:
  • Cat carrier
  • Playpen or secure enclosure
  • Cat beds, blankets, and towels
  • Heat lamp, heated cat bed, or incubator
  • Thermometer
  • Muslins, paper towels, or face cloths
  • Baby wipes
  • Non-clumping cat litter
  • Hand soap or sanitizer
  • Flea comb
  • Dawn dish soap
  • Disinfectant spray
  • Cleaning cloths
  • Cat scratcher
  • Cat toys

If a kitten is without their mother, you need to make sure you can keep a newborn kitten warm, as they can’t regulate their own temperature in the beginning. You can either use heat lamps, heated cat beds, or an incubator if you have access to one. Keep a thermometer near the kitten’s bed so you can monitor the temperature.

As the kittens grow up and start moving around, they may be interested in playing with toys, climbing small obstacles, and investigating scratching posts. Make sure you have a secure room where they can explore without the danger of falling down stairs, injuring themselves falling from high surfaces, or getting trapped behind furniture. By the time that kittens are roughly 4 weeks old, they’ll be starting to explore their environment, play with toys and each other, and get into all kinds of trouble!

It’s also a good idea to keep a supply of disinfectant and cleaning products on hand. Get into the habit of wiping the surfaces and vacuuming in your kitten’s room daily. A kitten’s immune system is still developing at this young stage, so you want to do everything that you can to minimize the chances of them picking up an infection.

What Should I Feed My Kitten?

Newborn kittens without a mother to provide milk should be fed a kitten milk replacer. The exact amount per feed will depend on the brand, so be sure to follow the manufacturer’s instructions. As a rough guide, newborn kittens will need roughly 2-6 milliliters per feed, increasing to 18-22 milliliters by the time that they are 5 weeks old.

Do not be tempted to feed your kitten cow’s milk. This can disrupt their digestive system and make them sick. In an emergency, you can use goat’s milk as a short-term substitution until you get a hold of kitten milk replacer. This should be available at vets, online, and in physical pet stores.

It’s a good idea to weigh your kitten every day to check that they’re putting on a healthy amount of weight. Newborn kittens usually weigh around 3.5 ounces and should gain an additional 10 grams each day. By keeping a close eye on your kitten’s weight, you can make sure they’re growing as much as they should be.

As kittens start to be weaned at around 6 weeks, make sure you provide a constant source of fresh and clean water. At this point, you can offer them a bowl of a soft kitten food, and pâté-type textures are usually well received! Mix a small amount of kitten food with pre-prepared formula, and put this in a shallow bowl. Expect the kittens to get a little messy as they explore these new taste sensations!

It’s also a good idea to offer a shallow bowl of formula as kittens get used to transitioning to a solid food.


How Do I Take Care of My Kitten?

Newborn kittens need round-the-clock care, so be prepared for sleepless nights. As they grow up, the frequency of feeds will reduce, but there’s still much you need to do to take care of these little bundles.


We’ve outlined how often you should be feeding your kittens here:
  • Age 0-1 week: Feed every 2-3 hours
  • Age 2 weeks: Feed every 3-4 hours
  • Age 3 weeks: Feed every 4-5 hours
  • Age 4 weeks: Feed every 5 hours
  • Age 5 weeks: Feed every 5-6 hours

At 6 weeks old, you can start weaning kittens onto a soft kitten food.

Keep everything clean when you feed your kitten, to minimize the chances of them picking up bacteria or an infection. It’s a good idea to keep an apron or coverall for feeding purposes only and launder this regularly.

Feed your kitten by allowing them to lie on their stomach. Some kittens will prefer to be held in your lap, while others may like to be on a towel on a flat surface like a table. Stroking your kitten’s forehead can encourage them to start suckling. Allow the kitten to set the pace, and you may need to support their neck with your free hand, especially for a newborn kitten. Once the kitten has had their fill of milk, encourage them to burp by patting their back. Next is helping your kitten go to the bathroom, which you’ll need to do after every feed.

Helping kittens go to the bathroom

Newborn kittens need help going to the bathroom. If their mother cat isn’t there to help them, you’ll have to do the job instead! After your kitten has had their feed, use a cotton ball dipped in warm water and rub this over their bottom in a circular motion. You may also need to rub your kitten’s belly. This should stimulate them to urinate and defecate. After they’re done, clean their bottom again with another cotton ball.

Kittens will need this help for the first 4 weeks, after which time, you can introduce them to the litter box.

Litter Box Training

Luckily, kittens are pretty smart at learning how to use the litter box. At around 3-4 weeks of age, you can place the kitten in a litter box and stimulate them to go to the bathroom like you’ve been doing previously. By 5 weeks old, kittens shouldn’t need help using the litter box to do their business.


Kittens will spend most of their time in their bed for the first 4 weeks. They’ll soon start to explore their new environment on wobbly legs, as they work on improving their coordination. They won’t need too much exercise before they tire out and head back to bed for something to eat and a nap!

Keep the area in which you allow your kittens to exercise fairly small, so there’s less chance of them getting into trouble. You can start to offer them a few toys at this point. Kittens should be allowed to choose when they want to exercise, so make sure they can always leave their bed from 4 weeks onward.


Kittens will usually learn socialization skills from their mother. If your kitten is being brought up without their mother cat, they will need extra help to develop their socialization skills. If you have a single foster kitten, you may want to see if you can find other kittens to integrate them with, if your vet recommends that as a possibility.

You can also help develop a kitten’s socialization skills by allowing them to interact with a range of people and other animals and exposing them to different sights and sounds. Making these experiences positive by rewarding your kitten with their favorite treat will help them grow into a confident adult cat.

Kittens will be due their first vaccinations at roughly 6 weeks and again at 12 weeks. Recommended vaccinations will vary depending on your location but can include:

  • FVRCP: A core vaccine that covers feline viral rhinotracheitis, calicivirus, and panleukopenia
  • Rabies (core): Protects against rabies, a fatal virus that can be transmitted to humans
  • FeLV (optional): Protects against feline leukemia virus
  • FIV (optional): Protects against feline immunodeficiency virus

How Do I Know If My Kitten Is Sick?

Keep a close eye on your kittens, and if anything seems out of the ordinary, it’s always worth asking your vet for advice. Newborn kittens are defenseless and fragile. As their tiny bodies grow and mature, they’re also working on building a strong immune system to fight off infections. Until they’re around 12 weeks of age, a kitten won’t have a fully functioning immune system. They can pick up a few different illnesses during this time. The main things to watch out for with newborn kittens are the following.

  • Upper Respiratory Tract Infection: This is a common illness for kittens, especially those that may have been abandoned or born outside. Abandoned kittens often haven’t had access to the vital first milk, or colostrum, from their mothers. This can make it more likely that they pick up infections. Symptoms of an upper respiratory tract infection include decreased appetite, heavy breathing, sneezing, runny eyes, and a discharge from the nose. They may also be lethargic. Kittens with a respiratory infection may not need antibiotics, but they will definitely need veterinary advice.
  • Fleas: They are common on small kittens, and as they’re too young for conventional treatments, you’ll have to remove the fleas manually. You may be able to bathe each kitten using a mixture of warm water and Dawn dish soap. Don’t use other dish soap brands, as they may not work as effectively. After bathing, make sure the kittens are kept warm until they’re fully dry. You can also use a flea comb to remove fleas, but some will inevitably jump off!
  • Dehydration: A newborn kitten’s small body can be prone to developing dehydration if they’re not drinking enough milk. A kitten’s urine should usually be a pale straw color — any darker than this and they may be dehydrated. Another way to test for dehydration is to pull up the skin between their shoulder blades. If it quickly drops back into place, they’re fine. If their skin remains pulled up, the kitten may be lacking in fluids. Speak to your local vet, as they may either recommend subcutaneous fluids or a supplement that you can add to your kitten’s formula.

Newborn kittens that have been abandoned should be taken to the vet for an assessment. After this, either speak to your vet if you think that the kittens have picked up an illness, or schedule another wellness check at around 9 weeks, when their first set of vaccinations are due. Kittens should have a booster vaccination at 12 weeks old, and it’s at this point that breeders will often allow them to go to their new homes.
