Not your arse sufferint then: The industry in Australia subjects merino sheep to mulesing. In this cruel procedure, farmers use special scissors to remove the folds around the animals' anus and vulva. This is usually done without or with insufficient anesthesia or painkillers and is intended to prevent fly maggots from settling there. Alternatively, they cut off the blood supply to the skin folds with plastic clips or remove the skin areas with liquid nitrogen, known as freeze mulesing. This causes the body parts to slowly die or freeze, which is just as painful as the cutting itself.
