Pissed off cat.

My neighbors cats. And one of them is not happy. There are some good speculations in the comments about whats going on. Some facts about the cats:
The angry one is a male, named Max. His behaviour was very unexpected, thats why I am giggling in the video.
All the cats in the video lived under the same roof since they were kittens, there was never any fights between them. Later on during this day I remember them all sleeping on the couch together as useual.
Cats gonna cat and humans will as always be confused over their behaviour.
Sadly Max passed away a few years after this video was taken.
