Pet cats and mankind have been residing in harmony for quite some time but that has not always been the situation. There have been times when felines have been almost wiped out in the name of God. And what occurred the Black Fatality reigned supreme for a lot longer than it will. So we will get back to the beginnings of recorded record to enough time of the pharaohs of Egypt. Here pet cats were revered as Gods and many were mummified to last for eternity. Because the felines guarded the grain warehouses and killed the rats and mice that given on the grain. Therefore minimizing famines, that were the curse of Egypt. It had been illegal to get rid of cats in those days, like cows in India today.
If this frame of mind towards cats goes back generations the other can realize why historians say the Black colored Death started in China. Where there are rats no cats then your rats dominate and that would have been a precursor for the condition to get near people. Now after i get back to China you may still find rats playing around but not so many in the housing estates. There are lots of down by the river. Also they have a very efficient rubbish tidy up system that continues the cities very clean. Where I stay the rubbish is accumulated everyday. That could also keep the rat populace down. And with so many discarded pet cats running around the rats don't have much of the opportunity. I've never seen this but I believe the government accumulates a lot of pet cats. There used to be colonies of stray cats surviving in some places but now I don't see them any longer.
