A death preceded by a moment of extreme tension, when the victim is convinced they are about to get savagely attacked, but then they realise it is actually just somebody's pet cat and they completely relax. At which point they are of course savagely attacked.
The "cat" can of course be anything laughably harmless, for example something flapping in the wind, a child's toy or a cute bunny rabbit.
The lesson to be learned is to always be in a state of manic paranoia and never let your guard down. Any innocent animals that scare you witless should be blown away to show any killers that may be lurking in the shadows that you are dangerously unbalanced and not worth messing with.
