I remember my aunt once sacrificed a cow (or a buffalo),I don't remember exactly,because her husband my uncle had passed away and all her kids were still young so she was the only one who could do it.The thing is the buffalo ran midway between the slaughtering,with it's half head hanging ,until it was overpowered by some people and then the sacrifice was completed,was crazy when I heard it!
I did sacrifice a couple of goats when I was a kid,felt a bit sad but was ok later on.During eid ul adha me and my father would watch the goat being sacrificed but my mother would go and hide in the inner most corner of the house ,she cannot bear to hear the voice it makes.But it is for the sake of Allah and there is nothing wrong in it,these are just human emotions,that is the essence of sacrifice.
