Kittens are adorable at any age, but did you know that figuring out how old a kitten is can help determine what sort of care they need? It can be tricky to tell, but our at-a-glance kitten progression guide, featuring Darling the kitten and his siblings, is here to help you out.
Before you do anything, remember: never separate kittens from their mother cat. If you don’t see her, monitor the kittens from a distance for a few hours. If their mother returns, Leave Them Be®.

Newborn Kitten
When kittens are first born they are completely helpless. Their eyes are closed, their ears are folded, and they can’t stand, keep themselves warm or eat on their own. They rely on mom for everything!
Darling as a newborn!
The First Week
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. Kittens like Darling, and his siblings, 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 percent of their time sleeping and the other 10 percent eating..

During their second week, Darling, Denby, Corduroy, Tweed, and Wembley continue to grow by leaps and bounds.
