Several ways of trying to guess the age of a kitten (but it is only an estimation of age) (Is this a very young, or older kitten?)
If there is still an umbilical cord attached to kittens belly, then kitten is around or less than 3 days old.
Eyes - open or shut? Kittens eyes start opening between around 8-12 days old.
Eye colour? - kittens are born with blue eyes. Eye-colour starts changing around 6-7 weeks old. (Few cats will retain their blue eyes into adulthood - depending on breed and genetics) So if kitten has blue eyes, he/she is probably under 7 weeks old.
Movement ~ Kittens will start trying to crawl around and/or stand upright and walk between 14 and 21 days (2-3 weeks old).
Alertness ~ after 3 weeks, kitten will start investigating noises and objects with interest.
Teeth ~ teeth start coming through at 2-3 weeks old, with a full set of teeth by 8 weeks. If kitten is starting to lose his/her front teeth, then he/she is at least 3 months old (then adult teeth will start coming through)
Toilet ~ Under 3 weeks old, kitten wont be toilet-trained. Watch to see if he/she attempts to use the litterbox, or not. Under 3 weeks, kittens will need stimulation (mother cats tongue, or cotton ball soaked in warm water), under the tail in order to urinate, etc.
