hello,
I would like to appeal with to a subject which is spread even today very much,namely the superstition of the misfortune by a black cat.
The subject was or is still in the western literature and also in modern films to symbolize the Bad, besides, the black cat is mostly used there because a lot of fairy tales were told their negative influence on People around , but also black dogs and crows are offered as a representation of the devil.
This superstition was one reason for subjugation of the Afro-Americans and its been not long ago when they got equal rights in Country they live.
To be honest who of ourselves has(had)not a bad feeling when a black cat crosses the street? some of the beliver of this Superstition turn around and leave quite fast the street and go somewhere else long because they have more fear of misfortune as to trust in the power of the creator.
In the Quran it is one of his signs that his creation is colourfull,in sura 30 "Ar-Rum":"And of His signs is the creation of the heavens and the earth, and the difference of your languages and colours. Lo! herein indeed are portents for men of knowledge. (22)
I think this can be transfered to animals too.
peace to all
