It's simply too unkind to compare an animal of any species to a follower of the ROP.
Crocodiles? Make wonderful mothers, they are superb survivors, can live in a dried up clay pan for six months and kick-start their metabolism as soon as it rains...and they eat very little and not very often.
Pigs? Have a high IQ. Learn fast, can do tricks, and are clean, very clean, if not penned up.
Vultures are the sanitation squad. Not pretty, but efficient and also very intelligent...
Hyena? Now there's an idea...
Lampreys. Like lampreys, almost every element of 'Islamic' culture is parasitic upon the technologies and concepts stolen from other peoples.
