Kitten Progression: At-a-Glance

Determining a kitten’s age can be difficult. Kittens develop at their own speed based on environmental and genetic factors. Observing physical signs, such as how open their eyes are and their weight, as well as behaviors, like when kittens begin venturing from their mother or using a litter box, will help. The photos and descriptions below can help you gauge the age of kittens with an unknown birth date.
