Spots can also be along the mouth or inside the mouth and on gums.

A while ago I noticed some dark spots on outside of my cats mouth and upon examining closer saw that dark spots are also inside his mouth. I do not know every single condition in animals but I am still learning… a never ending process !
I learned that these black spots are a condition which is seen in many cats, especially orange tabbies or calico cats. Black spots on your cats lips, nose, or eye margins is a condition called Lentigo Simplex. DO NOT BE ALARMED ! This is not a form of cancer ! It is completely harmless freckles just as freckles in humans.
The exact cause of Lentigo in cats is unknown. Regardless of the underlying trigger, Lentigo spots result from pigment-producing cells called melanocytes, making more melanin than the surrounding skin.
