"Toxoplasma gondii exerts a strange sort of mind control on rodents: Once infected with the brain parasite, they seem to lose their fear of cats and become more likely to get eaten."
Exposure to toxoplasmosis (which is carried by cats) causes mice to "fall in love with" cats (as some have expressed it). I sometimes think the same might be said of humans. 🙂
"Up to one-third of humans are thought to harbor a T. gondii infection, known as toxoplasmosis, and some research has linked it to schizophrenia and other mental illness."
See that proves it - We who love cats clearly have a mental illness. 🙂🙂🙂
