How to Estimate Kitten Age
Alley Cat Allies have excellent kitten progression photos, much more detailed than my notes here - check em out!

Kittens are usually around 100g when born and should put on about 100g a week, eg. a two-week-old kitten should weigh around 300g. These estimates can give you a rough guide to the age of your kittens. Do note that these are estimates only and are only intended as a rough guide - kittens from the same litter can differ by 100g or more depending on a number of factors; and a poor diet, or ill health, early on can hamper growth.
|Newly born to one week: Eyes are shut, ears are folded down and kittens are unable to walk. They can purr and make tiny noises. The umbilical cord may still be visible.
|One to two weeks: Eyes start to open (they are blue) and focus. Ears begin to open and movement is improved to crawling, snuggling, and kneading.
|Three weeks: Eyes fully open and ears are open and standing up. The kitten will start to respond to noises and movement. The first wobbly steps are taken and baby teeth start to come in.
