The medical condition responsible for googly eyes is called strabismus. Cats may be born with it or develop it later in life due to trauma or other illness, such as cancer or inflammation of the nerves. If your kitty inherited it, no treatment is needed as it shouldn't affect the vision of your furry friend. However, if your cat developed it, you should have it checked because it might indicate a serious illness besides just looking derpy.
