Pigs eat their exreta, should we imitate them too ? There also exists a spider in South America whose female is much larger than the male. When mating is complete, the female eats her mate.
Indeed Allaah has honoured the children of Aadam (i.e. mankind) as He says (what means): {And indeed We have honoured the children of Adam, and We have carried them on land and sea, and have provided them with lawful good things, and have preferred them above many of those whom We have created with a marked preference.}[Quran 17:70]
So why should a human being abandon the honour that Allaah blessed him with and leave the natural disposition with which Allaah created mankind and give evidence of the acts of animals to justify an abominable act which the innate moral character condemns and which is forbidden in religion?
Could it be possible as well to say why does a man not have sex with his mother, sister and daughter since animals do that, is this not madness?
Allaah Knows best.
