This movie was from the 70’s I believe it was Italian or of European creation. It had to do with a man that accidentally kills a bird. All the animals then begin to attack him. All animals…hilarious movie. He gets peed on by dogs, crapped on by a huge crane..at the end he is being committed to an insane asylum and all the nurses and doctors are wearing animal masks like pig and goats.
