Blitzcat by Robert Westall

AZ: "She made her way down the cliff, and on to the beach. At the edge of the waves, she stopped, shaking her wet paws. She knew that somewhere ahead was her person, but far, far away. She miaowed plaintively; stood staring at the moving blur of uncrossable sea. She led the way to safety, out of the blazing hell of blitzed Coventry. People touched her for luck; feared her as an omen of disaster. Wherever she went, she changed lives...From her beginning to her end she never wavered. She was the Blitzcat"

Realised when reading this have read it before but don't mind because very good, about a cat called Lord Gort psi tracking her (yes her) master during WWII and the people she meets and affects, written in third person but with a real feeling of dwelling in the cat's mind and with powerful descriptions of the bombing destruction of Coventry, life in Britain during WWII and what it was psychologically to be alive at that time, grieving, fearful, damaged, lonely, worn out, living with the very real threat of invasion at the time of Dunkirk/kerque.
