In this case, there's already been an altercation (not shown), and due to some writhing and twisting, the Tabby has a claw stuck intractibly hooked in the hide of the black and white (BW)cat's right forearm, meaning that the angle is such that he can't retract the claw and let thr B&W cat go. The B&W wants to pull away and withdraw, but he's stuck, pulling at the Tabby's claw, and this seems to enrage the Tabby further. The fight is on.

Notice This was not staged, it was merely a normal part of nature. I don't want to hear any crap from liberal morons or PETA folks. Personally, I love cats. I feed these two feral cats once a day (Obviously the tough Tabby eats first..). They eat less birds that way too. I also try to see that they are healthy. We can't save everything. For the record, the Tabby lets me pet him, he's nice and friendly but too wild to be handled or be put in a carrier to get fixed. The BW won't come near me and mostly gives me suspicious looks. As to the fight, it's not my doing, I am not these guy's keeper or boss, only a benefactor, and if anyone thinks I should reach in there to stop such an altercation, well.. just read the blow by blow again, and consider what can happen to a person's arm in two seconds when you have two unhappy 12-lb nonfat feral tomcats wrapped around it. That's 32 claws and 8 fangs.
This report is also a good illustration of why everyone should have their pets neutered. These two animals would not be in this rough situation: running the streets, fighting, living from trash cans, and begging for handouts if people would just get their darn pets neutered! The average life expectancy of an outdoor cat like these is 3-4 hard years (a 4 year old cat is equivalent in aging to a 45 year old person, but after 5 years, they age very slowly). Indoor cats typically live happily to 15 years or more (equivalent to 80 cat-years), bringing joy to their family.
