Nom nom kittens fighting over a fish

These kittens were playing when I approached them with fish.I had given both these kittens one fish each. Suddenly the friends became foes ! They started eating the raw fish with om nom nom nom sounds. One kitten finished its share quickly and tried to snatch the other one's share too. Then the sounds became louder and hissing also started. They love fish than any other food ! What I gave them was small raw sardine. They were very fresh fishes without any preservatives. I have given them this many times and the cats / kittens never had any problem after eating fresh raw fish.
