毕竟我喜欢猫而你姓苟
[bì jìng wŏ xĭ huān māo ér nĭ xìng gŏu]
'After All, I Like Cats While You Have Dog's Surname'. This is a playful or sarcastic take where the owner expresses a preference for cats while pointing out that the other person has a surname sounding like dog (苟 can mean 'dog' in certain contexts).
