Is Sunscreen (human) dangerous for cats?
No. Human sunscreen contains zinc oxide and/or avobenzone — both are toxic to cats if licked. White-nosed or thin-coated cats applied with human sunscreen 'to protect them' is a common veterinary emergency. Use cat-specific products only.

What's the full picture?
Zinc oxide — the active ingredient in many UK mineral sunscreens — causes haemolysis (destroys red blood cells) in cats at small licked doses.
Chemical sunscreens (avobenzone, oxybenzone, octinoxate) aren't acutely fatal but cause drooling, vomiting, and in larger amounts, neurological signs.
Cats do get sunburned — particularly white cats, and cats with sparse ear fur. If sun protection is needed, ask your vet for a cat-safe product. Never apply human sunscreen to a cat.

About this guidance
Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.
This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.
