After I Understood Cat Language, I Married the Prince

In 18th-century England, cat-speaking Clara is called a witch by locals and flees to a noble house as a maid. When the Prince falls mysteriously ill and his cat Gray weakens, the doctor blames a curse, ordering it burned.

At Gray’s plea, Clara uses science and vet skill to find deadly poisoned incense. She saves the cat, cures the Prince, unmasks the plot, winning his heart as maid turned savior.
