Also called: Age spots, liver spots, orange cat lentigo.

About: Also known as lentigo, areas of hyperpigmentation develop on the lips, gums and eye rims.

Symptoms: Flat, black spots on the eyelids, gums and lips of ginger, tortie and calico cats are common, they are the feline equivalent of freckles.

Treatment: No medical treatment is necessary for this condition.

Black spots on cat gums

Lentigo is the name of a common condition in which flat, brown or black spots appear on hairless areas including the gums, lips, nose and eye margins of orange, tortoiseshell, calico, yellow, flame (red) point cats. It is the result of an increase in the number of epidermal melanocytes – pigment-producing cells – which is results in hyperpigmentation.

Small spots around 1mm first appear on the lips, and later lesions can develop on the eyelids, gums, and nose. Lesions start out and become more widespread as the cat ages.


Black spots on cat nose

  • Flat lesions start on the lips as small spots and gradually increase in size and become more numerous as the cat ages.
  • Single or multiple brown/black spots (lentigines) which are small, flat or slightly raised, with a clear and defined border. The skin or mucosa surrounding the area is normal. The size of the lesions can range from 1-2 mm but can merge together to create larger areas of black pigmentation.
  • Most cats have single or a handful of lesions (lentigo simplex), others may have a significant number of lesions (lentigo profusa).


Black spots on cat eyelids

Freckles are associated with sun exposure in humans; however, the cause of lentigo is unknown in cats.


Black spots on cat gums

Lentigo is a benign condition, and most veterinarians can diagnose it based on presenting symptoms. In some cases, the veterinarian may recommend a biopsy with a fine needle for microscopic evaluation.


Lentigo is a cosmetic condition only and requires no medical treatment.

Black spots on cat’s lips and chin

Feline acne

Another cause of black spots which can occur on and around your cat’s lips unrelated to lentigo. Feline acne is the presence of black comedones (blackheads) predominantly on the chin but can also develop on the lips.

I have already covered this topic in detail here, so won’t go over it again. Acne can range from mild, as in the cat below to severe. Severe acne can become inflamed and progress to open sores on the chin, which will need treatment with antibiotics and medicated shampoos.
