...although it may not look it here, the feeding goes quite orderly:
Tollie throws a piece in the air, some jump to catch it, if one does it runs off with it and the others let it,
if it falls to the ground, they all jump to get it but if one does and runs off with it, the others
sort of accept that and turn for the next piece of meat, so every time the number of 'contestants' shrinks...
