"How Old is that Kitten?"
Kitten Progression: Nine Weeks Old
By nine weeks, the kittens are clearly showing an attachment to their caregivers, cuddling on laps and seeking out attention.
Fifty Seven Days Old
Their adult eye color is clear now: Darling, Denby, Corduroy, Tweed and Wembley all have yellow eyes.
Sixty Days Old
As they start to look more and more like adult cats, the kittens’ growth rate is finally beginning to slow. Though they will continue to develop muscle tone and stealth, they won’t be doubling their weight in a matter of days or weeks anymore.
Sixty Two Days Old
The kittens are on more of a schedule now, sleeping and eating at regular intervals. They eat mostly solid food, and mom is close to being done with the occasional nursing that may still be going on—if you were bottle feeding, you’re probably done by now.
Nine Weeks Old
The kittens are exhibiting all of the behaviors of adult cats, using their body language to communicate with their caregivers.
