Bringing home an 8 week old kitten is a big day, and it usually comes with a few questions. What should they actually be doing at this age? How much do you feed them, and will they let you sleep? This is a quick guide to what is normal at eight weeks and the handful of things worth sorting in the first week or two.
What should an 8 week old kitten be doing?
By eight weeks, a kitten should be weaned onto kitten food, using a litter tray, well coordinated and playful, which is why eight weeks is generally the earliest age a kitten goes to a new home. In many parts of Australia it is also the legal minimum. Many vets and behaviourists recommend leaving kittens with their mother and littermates for longer where there is a choice, often to around three to four months, as those extra weeks give them more time to develop their social and behavioural skills.
At eight weeks, you can expect your kitten to be:
- Curious, confident and busy, running, climbing and pouncing in short bursts before crashing for a nap
- Very playful, using that play to practise their social and hunting skills
- Just past the peak kitten socialisation window, so the focus now shifts to reinforcing good experiences and introducing new things slowly and positively
A little rough play with hands is common, so redirect it early onto toys. Our guide on how to stop a kitten from biting covers this.
How much should you feed an 8 week old kitten?
Kittens at 8 weeks should be eating kitten food only, to supply all the nutrients they need for optimal growth and development. This is not the time for adult cat food or cow's milk.
- Offer around three meals a day, with a mix of wet and dry
- Keep fresh water available at all times
- If your kitten arrives on a particular brand, keep them on it at first and switch gradually using our guide on how to introduce a new food to your pet
For amounts, follow the pack and check how much to feed a kitten and our feeding your kitten guide. If you are still choosing, start with the best kitten food.
Will an 8 week old kitten sleep through the night?
Possibly, but do not count on it at first. Kittens this age still sleep a great deal, though their body clock will not always match yours, and the first few nights in a new home are often unsettled. A little crying while they adjust is normal and usually passes within a week or two.
A calm, predictable first-night routine makes the biggest difference. Our new kitten checklist walks through it, our guide on how to set up your home for a new kitten covers getting the space ready before they arrive, and it is worth kitten-proofing your home before they start exploring at full speed.
What health care does an 8 week old kitten need now?
Three bits of admin are worth checking off at this age:
- Vaccinations: the first F3 is usually given from six to eight weeks, then boosted every three to four weeks until around sixteen weeks. If your kitten has already had their first shot, ask for the paperwork so your vet can plan the rest. See our kitten vaccination guide.
- Worming: usually every two weeks until twelve weeks of age, so check where your kitten is up to.
- Microchip: confirm it is registered in your name, which is a legal requirement in most of Australia. See microchipping your cat in Australia and council registration for cats.
Where does eight weeks fit in the bigger picture?
Eight weeks marks the start of the early juvenile stage (eight to twelve weeks), one step in a fast-moving first few months. Next comes the lively, into-everything phase our 3-month-old kitten guide covers, and you can see the whole picture in our kitten stages of development hub.
8 Week Old Kitten FAQs
A healthy 8 week old kitten is weaned, litter-trained, well coordinated and playful, and ready to settle in. Feed kitten food across about three meals a day, expect a few unsettled nights to begin with, and get the first vaccination, worming and microchip details sorted early.
