Alright, Someone has got to know this...?

From my understanding of it, the cat was supposed to be a symbolic metaphor for the state a martial artist aspire to which Bruce called "No Mindedness" or in plain English, "The Zone". If you notice, at the start of the fight Bruce was stiff and tense and basically got clobbered by Chuck because he kept reacting to Chuck's pace instead of establishing his own rhythm. When he realized what was happening, he decided to relax and dance around like a cat, making his reaction time shorter and his attacks more fluid. The cat also served as a contrast to the fury of the fighting, stretching lazily and playing in the corner while the two men fought strenuously. Of course, the whole fight scene could've been done without the cat in it. But Bruce was also into philosophy, so he probably included those scenes to show how a fighter should move like a cat. Besides, he probably needed to make the film time longer so the added cat scenes helped : P

It didn't have any significance. The cat was only there to add drama of flashing back and fourth between the fight scene. How boring would it be to just watch them fight with the smae music and the camera in just one spot? The cat sortof adds another world into the fight scene, oblivious to the fight. Innocence.

Just to add, I love that scene. I also love the one from Enter the Dragon where Bruce Lee breaks Jackie Chan's neck! It's so overdramatised, but I'll never stop seeing Bruce Lee as the best Martial Arts actor. I loved that Lee won. You hardly find a person that knows about him. It's all "Chuck Norris!!!" or "Jackie Chan!!!" or "Steven Seagal!!!" or "Van Dam!!!!" And Lee's sortof a role model for me. He wasn't a fighter, he was a Martial Artist, and I'll always respect that no matter how people make fun of it. He was a philosopher, a role model, not just a kick-butt fighter. Call me whatever you like, it's the truth.

Quite honestly, it is nothing more than another shot to cut away to. In that era, film makers believed that in order to show the magnitude of an event, they had to show every second of it and make it agonizingly long (i.e. the chariot race in Ben Hur and this - albeit awesome - fight between Masters). However, they also understood that you had to break up the imagery somehow or people would loose interest. Since there was nothing else to show in the area, they cut to the cat.

Wow, that is deep. I know the scene you are talking about. It is in the Colosseum. that place has many street cats that live there, i always just thought it was to build suspense in the fight scene, but perhaps it has a deeper meaning that is lost on me....perhaps it shows how the cat is patient, nimble and killing is as easy as play...just like Bruce

Its signifies how Bruce Lee saw the appeal of the cat in regards to food and won the fight so he would live and enjoy the tasty dish, sesame "chicken".

It's been years since I saw that movie, but I always kind of wondered about that, too.

As soon as the cart meows they start fighing!!!So I imagine the cat's meow is what sets them free to start fighting!!!!
