Kitten Progression: Week-by-Week
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.

When kittens are first born, they are helpless—they cannot see, hear, keep themselves warm, or eliminate waste on their own. They fit in the palm of your hand, and weigh 3-5 ounces. Callie, Penguin, and Ruby are completely dependent on their mother (or you!) for protection, warmth, and nutrition. Even so, these kittens can purr and make distress calls. They spend 90% of their time sleeping and the other 10% eating.
