Cats actually take a few parasites, a few fleas plus some diseases and some can change serious but not many. If felines were triggering too much sickness they would not need invaded our lives as well as they have. But there are still people out there who do nothing like felines. When I first went to China about twenty years ago there were very few felines living with people and incredibly few wild felines. I was astonished because I've possessed cats all my entire life and I never thought people didn't like felines. But then in China folks said cats carried disease and that was it. I feel that might have something regarding that cat sick you enter your eye. Not serious simply a moderate problem for a week And if you were pregnant you had to stay away from cats. I believe they were discussing toxoplasmosis, but if you get that whenever you are a kid it should not affect your child. In addition they said felines were soiled but I don't believe so. I believe felines are one of the cleanest house animals you could have. I think that originated from the cats eliminating the rats and mice. Because rats are extremely dirty family pets then because the cats wiped out and ate them they'll also be grubby. A soiled by connection kind of thing. Also there were some big sewer rats running round throughout the day. Once I noticed a rat and a kitty face off each other and the kitten wasn't much bigger than the rat. These were about a ft . apart staring each other out and the cat ran away. I'm not amazed the rat's tooth were bigger that the pet cats.
Then the nine lives of the humble kitty who only wanted to help mankind by killing rodents that carried disease took a significant flip for the more serious during the middle ages. Where witch hunts and burning at the stake were typical. Somebody who didn't like felines somehow connected them to witches and they were burnt at the stake with there owners. That they made that interconnection I'll never know. It began with Pope Gregory IX in the 1232 who regarded the normal house kitten as diabolical. Then to make matters more serious in1484 along came up the greatest pet cat killer of all time, Pope Innocent VIII, who decreed something such as all cats came from hell and really should returned to the fires of hell by hearth. Cats were mercilessly prosecuted and were burnt so they would return to the fires of hell. It is amazing any survived because if you were trapped with a feline you were burnt collectively. I still go to cathedral and sometimes I simply wonder why. And of course the Black Loss of life was in the backdrop surviving and thriving because there have been no pet cats to kill the rats that carried the fleas that caused the condition. Then along came up the cat's savior King Louis XIII of France, who in the 1630s repealed regulations and cats once more began to live. But they were still hated and wiped out for many decades from then on. I have no idea if the African american Death subsided but cats once again shielded mankind resistant to the diseases transported by rodents. And the famines brought on by mice plagues.
