Why are lucky cats in Chinese restaurants?

Excuse me, could you please shed some light on the presence of lucky cats in Chinese restaurants? I've noticed them in many establishments and I'm quite intrigued by the symbolism behind it. Is there a specific reason why they're commonly featured, or is it merely a cultural tradition that's been carried on through the years? I'd appreciate it if you could elaborate on the significance of these feline figurines and their role in Chinese cuisine and culture.
