Everyone has heard of those crazy cat ladies. They are those eccentric women who live in unkempt houses with their dozens of cats who can be seen eating and pooping all over the place. Well it turns out that she may have been made crazy by the poop.
Toxoplasma gondii is a parasite that lives in cat feces and can be transmitted to humans who come into contact with it. It can cause Toxoplasmosis that can make one ill or in rare cases be fatal. It is thought that about half of the world's population may be latently carrying it. What is interesting is that some studies seem to indicate that even when latent the parasite may have effects on human behaviour.
Could it be that the world is becoming ever more insane not because of any large social or economic developments but because of our affection for our feline friends?
