The lesion may be small, and it may affect one area of the body or multiple areas. The discoloration usually disappears within two to three months, but some cats develop permanent spots.

While some people believe that it is caused by an allergy to fleas or other insects, the real cause of cat lentigo is unknown. However lentingo is thought to be related to a protein called keratin in the cells of the skin.

 Keratin is a protein found in hair, nails and feathers. It’s also produced by some microbes and by some plants.

The spots can affect cats of any age and breed, but they tend to occur more often in middle-aged cats and those with thick fur coats. They may also appear more frequently when your cat spends a lot of time outdoors during the summer months or when she wears her winter coat indoors during cold weather periods.

Cat lentigo causes crusty lesions to form over the skin of your cat’s body. These lesions can be large (up to 2 inches in diameter) or small (less than 1/2 inch). The crusty lesions may also have white spots on them.

The symptoms of cat lentigo depend on where on your cat’s body they develop. If they occur near the mouth, there may be black like spots or patches.

How to differentiate feline acne from cat Lentingo

There are many differences between cat acne and cat lentigo. Cat acne is a skin condition that causes spots on the face of your pet commonly under the chine. The white or red bumps are itchy and can be painful for your cat.

Cat lentigo is a skin condition that causes small brown or black patches around the mouth, nose or eyelids of your cat. Sometimes, they can develop on the gums (causing black gums and bad breath).   These may appear as freckles or patches. The black spots are generally larger than those found in cat acne, but they are not painful for your pet.

The cause of lentingo in cats is unknown but there is evidence that suggests that feline acne can be caused by hormonal changes in cats. In addition to this, stress can also play a role in causing skin conditions in cats.

Cat acne is not contagious to humans, but if you have a cat with this type of skin disorder, you should wash your hands after touching it.


If your cat has black around his mouth, she most likely has lentingo.

It is worthwhile to know this condition is not dangerous for the cat, although it may in rare cases cause discomfort. It’s always a good idea to take your cat or kitten for some tests at the vet. Thats because there is a big list of possible skin and illnesses which can be a source of the problem.
