I've been interested in articles on toxo for a few years now. Some studies claim up to 60% of north American human population is infected, and up to 80% in south American countries!
There are also theories that toxo has directed human development such as with the ancient Egyptians, Altering their entire society. Another theory is that South American football/soccer teams do very well in the World Cup based on Toxo parasite causing the players to be more hungry to win and take more risks for the win.
In humans it is said to cause higher levels of aggression and risk-taking in males. High percentage of male victims of motorcycle accidents have been found to be infected. In females it is said to cause an increase in promiscuity.
Very fascinating that a parasite can enter a rat's brain and rewire their fear of cat urine to make the rat sexually attracted to cat urine. Results in the rat seeking out cat scented areas, being eaten and infecting the cat.
Happy to read in this thread that rat feces/urine is relatively safe, since I did not find that fact in a lot of articles.
I grew up with indoor/outdoor cats and I've been scratched and bit before, as well as cleaning that dreaded litter box in a poorly ventilated area, bleh. The possibility of being infected myself is mainly what sparked my interest in the subject, which should be more widely researched.
A cat seeking parasite which alters the human brain, very intriguing.
