Sunburn in cats: why white cats with pale ears are at risk
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A dark-coated cat has little to worry about from the sun, but a white cat, or one with unpigmented ears, is in a very different situation: its pale skin, poorly protected by melanin, burns much like the skin of a very fair-skinned person. Veterinary literature has long documented the link between repeated sun exposure and skin lesions in lightly pigmented cats, particularly on the ear margins and the nose bridge, with a risk of progression to precancerous lesions under chronic unprotected exposure.

Spotting the early signs
The most exposed areas are the edges of the ear pinnae, the eyelids and the nose bridge, where fur is thinnest and pigmentation often absent. Early sunburn shows up as redness, sometimes mild swelling and tenderness to the touch. Repeated over several seasons, these lesions can progress to persistent crusting, thickened skin or ulceration, which then calls for prompt veterinary attention.
Limiting exposure during high-risk hours
As with humans, the most dangerous hours fall between 11am and 4pm in summer. A cat with outdoor access, or one who loves napping on a sun-drenched windowsill, should be able to retreat to shade: offer a cool hiding spot indoors and limit garden access during the hottest midday hours, a topic we cover in detail for setting up the home for a heatwave.
Practical protection
Sunscreens specifically formulated for pets, free of zinc or salicylates that are toxic to cats, exist and can be applied to sensitive areas before an extended outing; never use a human sunscreen, several ingredients of which are dangerous if licked off. For very high-risk cats, a UV film applied to the window of a favourite sun-drenched sill also cuts UV exposure without depriving the cat of its favourite lookout spot.
Frequently asked questions
Are only fully white cats at risk?
No: any cat with unpigmented ears or nose, even one otherwise coloured, carries the same risk on those specific areas.
Does sunburn in cats heal on its own?
Mild redness fades within a few days in the shade, but lesions that persist or return every season should be examined by a vet.
Is sunscreen really necessary for an indoor cat?
If the cat spends long periods in the sun behind unfiltered glass, yes: glass blocks some UVB but lets through the UVA responsible for skin ageing.
