I think it was a book from the 70s or thereabouts, possibly older . A boy dies and is reincarnated or somehow put into the body of a cat. He is befriended by another cat who looks after him and teaches him how to behave like an actual cat.
That’s not a lot to go on but any help is appreciated.
Is this Jennie (1950) by Paul Gallico...?
This is the story of a young boy called Peter, who is knocked down by a car. To his considerable astonishment, when he recovers, he is not a young boy, but a cat!
Fortunately, he meets Jennie, a cat who had been abandoned by her family when they moved away, who educates him in the wiles of the feline world. Will he stay a cat with Jennie, or return to being a human boy?
