Cats with pale fur and light skin are especially vulnerable to sun damage, particularly on the ears, nose and eyelids. Repeated exposure to ultraviolet light gradually damages skin cells and can eventually lead to skin cancer, most commonly squamous cell carcinoma.
Cryotherapy is a treatment that uses extreme cold, usually liquid nitrogen, to destroy abnormal or cancerous tissue. The freezing process damages the targeted cells and stimulates the body’s natural healing response. Because it treats only the affected area, it is considered minimally invasive and is often used for small or early lesions.
Ultraviolet light damages the DNA inside skin cells. Over time, this damage builds up and the skin is no longer able to repair itself properly. The skin may first appear red or scaly, then develop crusts, thickened areas or non-healing sores. If left untreated, these changes can progress into aggressive squamous cell carcinoma.
Early detection is critical. Changes such as persistent redness, recurring scabs, areas that bleed easily, thickened skin or sores that fail to heal within a couple of weeks should always be checked by a veterinarian, especially when they occur on sun-exposed areas.
Reducing sun exposure is the most effective way to protect your cat. Keeping cats indoors during peak UV hours, providing shaded outdoor areas and using veterinarian-approved sunscreen on vulnerable skin can significantly lower the risk. For cats with very pale skin, permanent indoor living may be the safest option.
The best treatment depends on how early the lesion is found and how deeply it has spread. Cryotherapy is often very effective for small or early lesions. More advanced tumours may require surgical removal or radiation therapy, while late-stage disease may need a focus on comfort and quality of life.
Any suspicious skin change, particularly on the ears, nose or eyelids, should be assessed promptly. Early treatment can prevent the need for major surgery and greatly improve outcomes for cats affected by sun-related skin cancer.
