Pet cats and mankind have been surviving in harmony for quite some time but that hasn't always been the truth. There have been times when cats have been nearly wiped out in the name of God. And what occurred the Black Loss of life reigned supreme for considerably longer than it should. So we will get back to the origins of recorded background to enough time of the pharaohs of Egypt. Here pet cats were revered as Gods and many were mummified to last for eternity. As the felines guarded the grain warehouses and killed the rats and mice that given on the grain. Therefore reducing famines, that were the curse of Egypt. It was illegal to wipe out cats in those days, like cows in India today.
I think one of the reasons there were not many cats around is basically because they used to eat them. And every now and then the restaurant feline catches would pick up an kitty they may find and take them back again to the restaurant. I remember seeing pet cats in glass displays out the front of the restaurants. But somewhere between then and today they suspended eating cats. So cats are actually not on the menu and now there are cats everywhere. Many of them began in someone's house and acquired thrown away, because so many are incredibly friendly. Also they have got this thing about belly worms. And in those days China was not as modern as now so abdominal worms is a problem. Fleas aren't really a problem because they have got tile flooring and solid wood furniture.
