Just like human babies, all kittens are born with blue eyes. This is for the same reason as in humans − because the brown pigment melanin has not yet been deposited in the irises of the eye, or darkened by exposure to ultraviolet light. When it comes to other kitten facts about the body, it is a very different story. While kittens have similar eyes, their little noses are the equivalent of a human fingerprint, and no two noses are ever quite the same. Kittens also have a stronger and more dominant paw, just like we have a stronger hand. Interestingly, though, in kittens the difference is often gendered, and female kittens are usually right-pawed while their male siblings tend to be left-pawed.
