猫有一条命唯有一颗心
[māo yŏu yī tiáo mìng wéi yŏu yī kē xīn]
This translates to 'A cat has one life and only one heart'. It’s a play on the myth that cats have nine lives, instead emphasizing that despite having multiple chances at survival (nine lives), they are loyal with just one heart, symbolizing steadfast love or affection.
