What Chinese zodiac is cat?

Excuse me, but I'm curious about something. I've heard people mention the Chinese zodiac and the various animals associated with it, but I was wondering if you could clarify something for me. Specifically, I've been wondering if the cat is actually a part of the Chinese zodiac. Could you please explain whether the cat belongs to any of the 12 zodiac animals, and if not, why might that be the case? I'm genuinely interested in learning more about this aspect of Chinese culture and would appreciate your insights.
