📌 Key Points
- ✅ Kittens start weaning at about 4 to 6 weeks of age, and can be fully weaned once their milk teeth are complete at week 8
- ✅ Food should be changed in stages, with the solid proportion rising from one quarter to all
- ✅ Weigh the kitten at the same time every day; a plateau or drop means something is wrong
- ✅ At 4 to 6 weeks, feed 4 to 6 times a day, gradually reducing the milk formula proportion
- ✅ If the kitten eats nothing for two consecutive days, or has bloody diarrhoea, see a veterinarian as soon as possible
"When can a kitten stop drinking milk?" "Will changing food too fast cause diarrhoea?" Weaning is a hurdle every kitten must pass; handle it well and the gut adapts smoothly, making appetite and weight gain much more stable afterwards. Here we draw on feeding data from the Book OCR cat encyclopedia to put together a staged timetable, tips to tempt eating and a daily feeding chart, to help you guide your kitten safely from the bottle to solid food.
When does kitten weaning begin?
Most kittens begin weaning at 1 to 1.5 months after birth (about 4 to 6 weeks of age), with some weaning only at 6 weeks; by week 8 the milk teeth are complete and they can basically be fully weaned.
- 3 weeks: weight about 500 g, start trying mushy weaning food
- 4 weeks: milk teeth almost complete, can eat weaning food and kitten-specific food
- 4-6 weeks: also enters the prime socialisation period, learns to play with littermates and regulate body temperature
- 2 months: milk teeth complete, weight 700-1000 g, also the time for combination vaccines
Staged food transition timetable (week 4 → week 8)
| Stage | Key feeding points |
|---|---|
| Week 4 | Mainly milk, add about half a teaspoon of minced weaning food, feed by spoon, 4 times a day; solids 1/4, milk 3/4 |
| Week 5 | Put weaning canned food on a shallow dish for the kitten to lick; solids still about 1/4 |
| Week 6 | Solids increase to more than half; weaning formally begins |
| Week 8 | Fully weaned; 2-3 solid meals a day plus a small dish of milk, can switch to kitten dry food |
Daily feeding frequency during weaning (4 weeks to 2 months):
- 4-6 weeks, 300-500 g: 4-6 times a day, mix milk formula with weaning food, gradually reduce the milk formula and increase the weaning food
- About 600 g: 4-6 times a day, switch completely to weaning food over 1-2 weeks and stop the milk formula
- 1.5 months, about 800 g: 4-5 times a day, soften the food but keep its shape so the kitten learns to chew
- 2 months, about 1 kg: 3-4 times a day, change from softened food to dry food within 1-2 weeks
How to tempt a kitten to eat solids: 4 practical tips
-
Smear on the lips: put a little weaning food at the kitten's mouth for it to lick
-
Mash into porridge: mix dry or wet food with warm water at 1:3, starting thin and gradually reducing the water
-
Warm to release aroma: gently warm the food to release its smell and stimulate the sense of taste (do not add garlic or onion)
-
Learn by imitation: once one starts eating, the other kittens follow; feeding littermates together works best
5 key precautions during weaning
-
Weaning itself is stressful: the gut is receiving new proteins, carbohydrates and fats for the first time, so small, frequent meals are safest at first
-
Changing too fast causes constipation: a big change in food type and amount disrupts the gut flora, so always change in stages
-
Fresh water must always be available: to avoid dehydration; if the kitten won't drink, thin the food with warm water into a porridge
-
Weight gain is fastest before 3 months: growth slows after 4-5 months, so the amount fed should be reduced accordingly
-
Body shape is set by 10-11 months: adding more food at random only leads to obesity, so feed at set times and amounts
Reference daily feeding amounts for kittens (g): 0-4 months 0.5kg→30g, 1kg→50g, 1.5kg→70g; 4-6 months 1kg→40g, 1.5kg→55g, 2kg→70g; 7-12 months 1kg→35g, 1.5kg→45g, 2kg→55g. Adjust the actual amount according to the food packaging and your veterinarian's advice.
When should a kitten see a veterinarian during weaning?
Do not delay in the following situations; seek veterinary help as soon as possible: eating nothing for two consecutive days, diarrhoea with blood or mucus, frequent vomiting, weight failing to rise or falling for several days in a row, lethargy, pale gums. Kittens in the weaning period have weaker immunity, and dehydration and low blood sugar can worsen quickly, so it is better to have one early check-up.
Weighing daily is the best way to monitor
Prepare a small scale and weigh at the same time every day, keeping a record. A healthy kitten's weight should rise steadily, for example from 500 g to 700 g to 1 kg; if weight stalls or drops even for one day, it means the feeding amount or health status has a problem, and you can adjust early.
Keeping a kitten in Hong Kong: preparing for weaning
For orphan kittens adopted without a mother cat, the equipment must be complete: kitten milk formula and bottles (do not substitute cow's milk), weaning canned food or kitten weaning food, a shallow dish and a scale. The PetChill website has kitten milk formula, weaning canned food, kitten dry food and bottle sets, so you can buy everything at once.
PetChill's Reminder
The key to weaning is "slow" — move through the stages from week 4 to week 8, waiting for the gut to adapt before each next step. During this time, weigh daily and watch the stools; if there is persistent diarrhoea, constipation or lethargy, consult a veterinarian immediately.
