My vet advised a children's sun cream for a cat with white ears, as it is the ears which are vulnerable to cancer, also the top of the nose if it is white. If your cat's ears are ginger that will be ok. If they are white, you need to check with your vet for a suitable suncream, which won't harm the cat if it licks some when it washes itself. Also during the summer the suncream should be applied every day. I would suggest that you discuss this with your vet. Best wishes.
