My kitten has one white ear and the vet said white ears are prone to cancerous tumors when exposed to the sun. He recommended using a sunscreen. He also said indoor cats are especially proned because they lay in the window siles in the cool of the house in summer. Outside cats usually keep in the shade.

I’m wondering if there is a sunscreen for cats that work better than people sunscreen. Does anyone know?

Also, has anyone had a white cat that has developed cancer tumors and if so, what can be done?
