At two weeks, kittens’ eyes are fully open, but they have not got their adult pigment yet so will still appear blue or gray, and their vision is still not clear. They are also still sensitive to light, so no matter how cute your little fluffy-puffs are, please don’t use flash photography or shine bright lights towards them!
Their sense of hearing is still weak, but their sense of smell is starting to develop.
Two-week-old kittens are more aware of their surroundings and are starting to interact with each other and with you. The more adventurous members of your litter might be trying to climb out of the box to go exploring. Mother cat won’t let them, as they’re still too little, so you can help her out by making sure the doorway is high enough that they can’t climb out.
Two-week-old kittens should be six to eight ounces and have fat tummies and clean faces. If you think your kittens are not growing well, or don’t seem healthy, take the whole family to the vet. You might need to supplement Mum’s milk with some kitten formula via a kitten baby bottle.
