猫有九命仅有一心而已
[māo yŏu jiŭ mìng jĭn yŏu yī xīn ér yĭ]
'A cat has nine lives but only one heart'. Cats are believed to have multiple lives for their resilience. This saying stresses the depth of one's emotional commitment, suggesting no matter how adaptable or changeable they might seem, their true devotion lies only in one place.
