Thomasina: The Cat Who Thought She Was a God - Paul Gallico - Bog

"Seven-year-old Mary adores her ginger cat, Thomasina, and is crushed when Thomasina falls sick, and Mary's father, a grim, inflexible man who is the town vet, decrees that the only thing to be done is to put Thomasina down. Mary refuses to speak to her father, and then she herself contracts a life-threatening disease. In the meantime, however, Thomasina has been rescued--by the mysterious Lori, the Red Witch of the glen. Thomasina is now Talitha, the descendant of an Egyptian goddess, and she is coming back to seek revenge!"--Back cover.
