Excuse me but who would you rather trust if you were the police officer. 

1. A calm sober guy that likes his cat.
Or.
2. An agressive drunk dude that wants to throw hands.

Edit: Also depending on where he lives the guy kicking his cat might cover him up legally as pets are often considered property.

The sober guy just beat on a man multiple times for 30 minutes, so I highly doubt he's calm; plus at that point the drunk guy is probably nothing but a bloody mess. Doesn't matter who started the fight visually the whole thing is bad.
