Q. Two of my cats bridge of their noses are turning black and that is not their natural color

A. It may just be a normal change in pigment color but could be secondary to a medical condition. Have them examined by a vet to determine the cause. Allergies, skin infections, endocrine diseases, and skin cancers can cause hyperpigmentation of the skin. Your vet can do some diagnostic tests, like skin scrapings, cytology, biopsy, and/or bloodwork, to determine the cause and best treatment.
