When I was in college, a student made a film titled: 'How to clean a Fish'. If it had been about gutting a catch, I would have called that a documentary. He placed a live fish on newspaper and sprayed it with industrial cleanser, the conclusion of the piece was to watch the fish flop and gasp till it died-I would call that a crime. Given the title of this work, 'Casuistry: The Killing of A Cat' (I HAVE NOT SEEN THE WORK) I'm assuming the filmmaker is trying to draw some parallels to other ways in which we kill animals for our needs which are acceptable (like hooking a fish instead of spraying it), or our selection as to which animals are pets (and 'deserve ' exemption), which are food, and which are sport. An effort to diminish the brutality of this one act so it doesn't look so monstrous in comparison. I understand the weaving through semantics which make some animals deaths 'acceptable'. What I don't understand is the cat was killed simply to watch it suffer and die, how can THAT be justified through any wordplay or any amount of convoluted 'reasoning'?
