If the Hedgehog food dish is empty then it is always worth checking underneath in case anything fell through the mesh. Not the easiest thing to do when your spikes get caught in the holes.
I have seen Hedgehogs charge at each other on many occasions but this one seems to have succumbed to food rage when it caught another eating what it thought was its private stash of free food. A real Hedgehog temper tantrum as can be seen in the first half of the clip. Both ended up with a share of the food and each went its separate way in the end. The only injury seems to have been to pride.
