Newborn kittens: when to handle them and how to care
For the first two weeks, newborn kittens are handled only when there is a reason — weighing, moving the nest, or a visible problem. Not because touch harms them, but because the mother is at her most strained and every lift costs nursing time and warmth. From week two to week seven the opposite is true: this is when a kitten learns that people are normal, and short, regular contact shapes its character.
- When you do handle them: clean warm hands, one kitten at a time, in front of the mother, briefly. A newborn cannot hold its own heat and chills within minutes.
- If the mother is present and caring for them, intervention is unnecessary. If she growls or moves the kittens, leave her be — moving them is normal behaviour, not aggression towards you.
- Orphaned and visibly failing kittens are the exception. There, waiting is more dangerous than intervening, and the question is no longer when to touch them but how fast you can reach a vet.
When and how to handle them
These rules apply while the mother is with the kittens and caring normally. For orphaned kittens everything changes — they depend on a person entirely.
- day 1 – 3Only when needed. The first 72 hours carry the highest risk and every lift takes time away from the teat. A once-daily weighing is the exception worth making.
- to 2 weeksShort and for a reason. Warm clean hands, both hands under the kitten, back in the nest within a minute or two. Children watch; they do not carry.
- 2 – 7 weeksThe window in which a kitten learns that humans are ordinary. Brief daily contact with different people at this age shapes its temperament for life.
- every timeIn front of the mother, not in another room. Once a kitten leaves her sight she becomes stressed, and a stressed queen eats less and nurses worse.
- immediatelyIf a kitten is limp, cold to the touch, not suckling or crying constantly — that is not something to leave until morning.
It is a myth that a mother abandons a kitten because it "smells of human". A domestic cat does not reject her kittens over your scent. What does affect her is disturbance — frequent lifting, noise and moving the nest.
What happens week by week
A guide to a kitten’s age and to what is normal. A day or two either way is ordinary; falling a whole week behind is worth a conversation with your vet.
| Age | What happens | What is asked of you |
|---|---|---|
| Week 1 | Blind and deaf; cannot hold body heat | Keep the nest at 29 – 32 °C. Birth weight is around 90 – 100 g and should gain 10 – 15 g a day. Weigh at the same time every day. |
| Week 2 | Eyes open, usually between day 8 and day 12 | Nest temperature drops towards 27 °C. Weight has doubled from birth. Vision is poor — no bright lights in the eyes. |
| Week 3 | Hearing opens; first unsteady steps | The socialisation window begins. This is the moment for short daily contact with people, calm sounds and different surfaces. |
| Week 4 – 5 | Walks confidently, plays, tries solid food | Room temperature can be 22 – 25 °C. Offer wet kitten food without stopping nursing. The litter tray is introduced now. |
| Week 6 – 8 | Weans; baby teeth come through | By about week seven most kittens are fully weaned. The first RCP vaccine is given at 8 – 9 weeks. |
| Week 9 – 12 | Learns from the mother and the littermates | A kitten should not change homes before 12 weeks. What is learned in these weeks is not made up later. |
Why newborn kittens die
Pre-weaning mortality runs between 15 and 30%, and more than half of those deaths fall in the first two weeks. Usually the cause is not one disease but a chain that starts with chilling.
The kitten chills → loses its suckle reflex → stops nursing → blood sugar falls → weakens further → chills further. The loop closes within hours. That is why the first thing a failing kitten needs is not food but warmth: milk given to a cold kitten is not digested and can do harm.
What sits underneath
Chilling and low blood sugar
A newborn does not regulate its own temperature for the first weeks. A cold nest, damp bedding or a mother away too long is enough.
- A nest below 29 °C in the first week
- A kitten cold to the touch across the belly
- A limp body with no response to being lifted
Not getting enough milk
A kitten born light or with a weaker reflex loses its place at the teat. The first milk — colostrum — carries immunity and is absorbed only in the first hours.
- Birth weight under 75 g
- No gain, or a drop, two days running
- A queen with mastitis, little milk, or a hard birth
Infection and congenital problems
Infection through the navel, viral causes, heart and palate defects, and blood type incompatibility in pedigree cats.
- A swollen or damp navel
- Diarrhoea, bloating, laboured breathing
- Milk coming down the nose during nursing
When to call a vet immediately
- The kitten is cold to the touch and limp
- No weight gain two days running, or weight lost
- Not suckling, or lying apart from the others
- Crying constantly instead of sleeping between feeds
- Laboured or open-mouthed breathing, or milk from the nose
How long the mother cares for the kittens
Nursing lasts around six to eight weeks, but care does not end with milk. Between weeks eight and twelve the mother teaches a kitten what a person cannot: how hard to bite in play, how to use the tray, when to stop. That is why 12 weeks is the floor for changing homes — not because a kitten cannot eat on its own, but because it will not have learned the rest. Dogs follow a similar shape: nursing ends around 6 – 8 weeks, and the recommended minimum for separation is 8 weeks, with 10 – 12 better for most breeds.
Common questions about newborn kittens
When can newborn kittens be touched?
From day one, if there is a reason — daily weighing, for instance. But for the first two weeks contact stays at what is necessary: clean warm hands, one kitten, in front of the mother, for a minute or two. From week two to week seven the opposite holds — brief daily contact with people matters for the kitten’s character.
Is it true that a cat abandons a kitten that smells of humans?
No. A domestic cat does not reject her kittens over human scent. What can make her move them or neglect them is stress: frequent disturbance, noise, movement around the nest, or a sense that the place is not safe. A quiet, tucked-away nest solves that.
Why do newborn kittens die?
Usually not from one disease but from a chain that starts with chilling: a cold kitten loses its suckle reflex, stops nursing, blood sugar falls and the weakness deepens. The other common causes are insufficient milk, missed colostrum, infection through the navel and congenital defects. Pre-weaning mortality is 15 – 30%, with more than half of the cases in the first two weeks.
When do kittens open their eyes?
Usually between day 8 and day 12, with vision cloudy and weak at first. The ear canals open around day 17. Full sight and hearing settle at about six weeks. If the eyes have not opened by day 14, or there is discharge and swelling, that warrants an examination.
How much weight should a kitten gain per day?
Around 10 – 15 grams a day in the first weeks. Birth weight for most breeds is 90 – 100 grams and should double within one to two weeks. Weighing daily, at the same time, on the same scale, is the earliest warning you get — earlier than any visible symptom.
What do I do if I find orphaned kittens?
Warm them first — before anything else, food included. A cold kitten cannot digest milk. Use a kitten milk replacer, never cow’s milk. Feeding is every 2 – 3 hours in the first week, through the night as well, and after each feed the belly is stimulated with a damp cloth. Orphaned kittens should be seen by a vet as soon as possible.
When can a kitten leave its mother?
Not before 12 weeks. Nursing ends around 6 – 8 weeks, but the month after that is when a kitten learns social rules from its mother and littermates — how hard to bite, when to stop, how to use the tray. Kittens taken at 8 weeks more often have problems with biting and anxiety.
The scale speaks first
With newborn kittens weight is the earliest signal — it turns down days before anything else shows. The trouble is that numbers on paper get lost and the trend does not stand out. In PetsClub each kitten has its own record and the curve is visible at a glance.
- A separate profile per kitten in the litter, with a weight curve
- A reminder for the daily weighing, for as long as it is useful
- Records export as PDF — useful at the vet and at rehoming
