Cats actually take a few parasites, a few fleas and some diseases and a few can change serious however, not many. If pet cats were causing too much sickness they would not need invaded our lives as well as they have. But there are still people out there who do not like cats. When I first visited China about 20 years ago there were very few pet cats coping with people and incredibly few wild felines. I was surprised because I've possessed cats all my entire life and I never thought people didn't like pet cats. But in China the individuals said cats transported disease and that was it. I think that may have something to do with that cat sick and tired you enter your vision. Not serious simply a slight problem for weekly In case you were pregnant you'd to keep away from cats. I believe they were discussing toxoplasmosis, but if you get that when you are a kid it will not affect your baby. They also said cats were grubby but I don't think so. I think felines are one of the cleanest household pets you could have. I think that originated from the cats eradicating the rats and mice. Because rats are incredibly dirty pets or animals then because the felines killed and ate them they'll also be dusty. A dusty by connection type of thing. Also there have been some big sewer rats working round during the day. Once I noticed a rat and a cat face off each other and the cat wasn't much bigger than the rat. These were about a foot apart staring each other out and the cat ran away. I'm not shocked the rat's teeth were bigger that the pet cats.
Then the nine lives of the humble cat who only wished to help mankind by eliminating rodents that taken disease took a serious convert for the even worse during the middle ages. Where witch hunts and using up at the stake were the norm. A person who didn't like felines somehow connected them to witches plus they were burnt at the stake with there owners. How they made that interconnection I'll never know. It began with Pope Gregory IX in the 1232 who considered the normal house feline as diabolical. Then to make things worse in1484 along came the greatest kitty killer ever, Pope Innocent VIII, who decreed something such as all cats came from hell and really should went back to the fires of hell by open fire. Cats were mercilessly prosecuted and were burnt so they might return to the fires of hell. It is amazing any survived because if you were caught with a kitty 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 were no pet cats to get rid of the rats that transported the fleas that induced the disease. Then along came up the cat's savior King Louis XIII of France, who in the 1630s repealed regulations and cats once again started to live. However they were still hated and killed for many generations after that. I have no idea if the Black color Loss of life subsided but felines once again secured mankind resistant to the diseases carried by rodents. As well as the famines due to mice plagues.
