If this attitude towards cats goes back generations the other can realize why historians say the African american Death were only available 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 to people. Now while i go back to China you may still find rats playing around however, not so many in the real estate estates. There are several down by the river. Also they have a very efficient rubbish clean up system that continues the metropolitan areas very clean. Where I stay the rubbish is accumulated everyday. That would also keep carefully the rat inhabitants down. And with so many discarded pet cats playing around the rats don't possess much of the opportunity. I've never seen this but I suspect the government accumulates a lot of felines. There used to be colonies of stray pet cats surviving in some places but now I don't see them any longer.
I believe one of the reasons there were not many cats around is because they used to consume them. And once in a while the restaurant cat catches would grab an kitty they may find and take them back to the restaurant. I remember seeing felines in glass exhibits out leading of the restaurants. But somewhere within then and now they restricted eating pet cats. So cats are now not on the menu and today there are felines everywhere. Many of them started off in someone's house and got thrown away, since several are very friendly. Also they have this thing about abdominal worms. And in those days China was not as modern as now so tummy worms is a problem. Fleas are not really a problem because they may have tile floors and wooden furniture.
