There are many ways your cat might be filling you with rage. Scratching your furniture, sitting on your computer keyboard – or giving you parasites that may cause explosive anger.
Infection with Toxoplasma gondii, a protozoan parasite carried by cats, has been linked to a human psychiatric condition called intermittent explosive disorder. People who have IED typically experience disproportionate outbursts of aggression, like road rage. T. gondii is already known to change the behaviour of the organisms it infects. By making rodents bolder and more adventurous, the parasite makes them more likely to be caught and eaten by a cat, allowing the parasite to complete its life cycle.
