Weaning runs from week 4 to week 8, and the whole job is done in 4 stages of about 7 days each. A kitten that is still on milk at 8 weeks is not late in a dangerous way, but it is behind: solid food intake, weight gain, and stool quality all depend on starting the transition by day 28. The rule that keeps it simple is 1 new texture per week, 4 to 6 small meals a day, and a weight check every 3 days.
Why the window is 4 to 8 weeks
At 3 weeks a kitten has teeth breaking through and a stomach built for milk; by 4 weeks it can lap, and by 6 weeks it can chew soft food. The suckling reflex fades between 6 and 8 weeks, which is also when the queen starts refusing to nurse and walks away. Milk alone stops meeting energy needs around week 4 to 5: a kitten needs roughly 200 to 250 kcal per kg per day, and milk supplies about 1 kcal per mL, so a 500 g kitten would need 100 to 125 mL a day, more than most queens produce. Waiting past 8 weeks makes the kitten harder to rehome and slower to accept new textures. An orphaned litter raised on a bottle follows the same 4 week start, with 6 to 8 feeds a day at 2 to 3 hour intervals for the first 2 weeks.
The 4 stages, week by week
Each stage lasts about 7 days. Move to the next stage only when the kitten finishes its meals and gains weight for 3 days in a row. The ratio is milk replacer to solid food by volume.
| Stage | Age | Food and ratio | Meals per day | Amount per meal |
|---|---|---|---|---|
| 1 | Week 4 | Replacer plus canned food, 3:1 | 5 to 6 | 10 to 15 mL |
| 2 | Week 5 | Replacer plus canned food, 1:1 | 4 to 5 | 20 to 25 mL |
| 3 | Week 6 | Mashed canned food, no replacer | 4 | 25 to 30 g |
| 4 | Week 7 to 8 | Dry kibble plus water, or pate | 3 to 4 | 30 to 40 g |
Stage 1: the first lap at 4 weeks
Warm 30 mL of kitten milk replacer to 38 degrees Celsius, whisk in 10 g of canned kitten food until there are no lumps, and offer it on a shallow saucer 5 to 6 times a day. The kitten will walk into the plate, sneeze, and wear more than it eats for the first 2 days; that is normal. Keep the queen's food separate and let the kitten nurse 2 to 3 times a day so the transition is gradual. Never use cow's milk, which has about 3 times the lactose of cat milk and causes diarrhea within 12 hours.
Stage 2 and 3: thicker every week
At week 5 raise the solid share to 1:1 and drop to 4 to 5 meals; the mix should hold a spoon upright for a second. At week 6 remove the replacer and mash canned food with a fork, adding warm water if it crumbles. Offer fresh water in a shallow bowl from week 4 onward, and refresh it 2 times a day. Around week 6 the kitten's stool changes with every new texture, so judge by the trend over 3 days, not by one loose stool.
Stage 4: dry food and the last 7 days
At week 7 put down dry kitten kibble, 3 to 4 mm in size, and a separate bowl of water; some kittens need the kibble softened with 2 tablespoons of warm water for the first 3 to 4 days. From week 8 the kitten should be on 3 to 4 meals of complete kitten food and no milk at all, with food left down for no more than 30 minutes per meal. Free feeding after 8 weeks is the main reason kittens become overweight adults, so measure the day's ration once in the morning. A 500 g kitten at week 4 needs about 100 kcal a day; the same kitten at 800 g in week 8 needs about 180 kcal, which is why the amount climbs at every stage.
Three indicators that weaning is on track
The first is weight: from week 4 to week 8 a kitten should gain 10 to 15 g a day, or 70 to 100 g a week, and be roughly 3 times its birth weight at 8 weeks. Weigh on a kitchen scale at the same time every 3 days and write the number down; a flat line for 2 checks is a reason to call the vet. The second is stool: formed, brown, and easy to pick up, with no blood and no water ring on the paper. The third is intake: each meal should be finished in 10 to 15 minutes, and the kitten should take roughly 200 to 250 kcal per kg per day by week 8, which works out to roughly 130 to 170 g of canned food per kg of body weight.
What goes wrong, and when to call
Diarrhea that lasts more than 24 hours, weight loss at any check, vomiting more than 2 times in a day, a kitten that refuses food for 12 hours, or a kitten that is cold to the touch and quiet needs a vet the same day; small kittens dehydrate in under 24 hours. Do not add supplements, vitamins, or human baby food to stretch the ration, and do not switch brands more than once in a stage. A kitten that eats litter, chews the bowl, or cries at the empty plate is usually getting meals that are too small or too far apart.
The week-by-week diagram lives in our weaning schedule, and the grind-and-consistency details are in the food texture guide.A 7-day checklist you can print
- Day 1 to 3: weigh, warm the food to 38 degrees C, offer 5 small meals, and let the kitten nurse 2 to 3 times.
- Day 4 to 6: thicken the mix, cut to 4 meals, and add a shallow water bowl.
- Day 7: weigh again, and move up a stage only if weight rose and stools stayed formed.
- Week 6 and week 8: ask the vet to check teeth, weight, and stool, and to set the next vaccine date.

Frequently asked
Can I start weaning at 3 weeks instead of 4?
Only if the kitten is orphaned or the queen has no milk. At 3 weeks the teeth are just breaking through and the stomach is built for milk, so gruel often causes diarrhea. A healthy kitten with a queen does best starting at day 28, with 1 new texture per week until week 8.
How much weight should a kitten gain each week while weaning?
About 70 to 100 g a week, or 10 to 15 g a day, from week 4 to week 8, ending at roughly 3 times the birth weight. Weigh at the same time every 3 days; a flat line across 2 checks means the ration, the texture, or the kitten's health needs a vet's look.
When should milk be completely gone?
By week 8. Stage 4 at week 7 keeps 3 to 4 meals of dry kibble or pate, and the replacer is dropped at week 6. A kitten still nursing at 8 weeks can continue, but it should already be eating full meals of kitten food on its own.
