Cats actually hold a few parasites, a few fleas plus some diseases and a few can change serious but not many. If cats were causing too much sickness they might not need invaded our lives as well as they have got. But you may still find people out there who do not like pet cats. When I first visited China about twenty years ago there were very few felines coping with people and very few wild cats. I was surprised because I've had cats all my life and I never thought people didn't like felines. But then in China folks said cats carried disease which was it. I feel that might have something to do with that cat sick and tired you get in your eyeball. Not serious only a little problem for weekly And if you were pregnant you'd to stay away from cats. I think they were discussing toxoplasmosis, but if you get that whenever you are a youngster it should not affect your baby. They also said cats were dirty but I don't think so. I believe cats are one of the cleanest dogs and cats you could have. I feel that originated from the cats killing the rats and mice. Because rats are extremely dirty animals then because the cats killed and ate them they will also be soiled. A soiled by connection type of thing. Also there have been some big sewer rats operating round throughout the day. Once I noticed a rat and a kitty face off the other person and the pet cat wasn't much bigger than the rat. These were about a feet apart staring the other person out and the cat ran away. I'm not stunned the rat's tooth were bigger that the felines.
Cats and mankind have been residing in harmony for many years but that has not always been the situation. There were times when pet cats have been almost wiped out in the name of God. And what happened the Black Loss of life reigned supreme for a lot longer than it will. So we will get back to the beginnings of recorded background to the time of the pharaohs of Egypt. Here cats were revered as Gods and many were mummified to last for eternity. As the felines guarded the grain warehouses and wiped out the rats and mice that given on the grain. Therefore lowering famines, that were the curse of Egypt. It had been illegal to destroy cats in those days, like cows in India today.
