4. Which came first, the crazy or the cats?

It has been hypothesized that the parasite Toxoplasma gondii, whose primary host is the housecat, can mess with the mind. Studies show that infected mice lose their fear of cats, making them even more susceptible to cat consumption, which in turn infects the cat. Previous studies have suggested that having a cat for a pet could be linked to mental disorders like schizophrenia as well as depressive disorders (and popular culture has confirmed this bias with the crazy cat lady stereotype) due to exposure to the t. gondii infection. Well crazy people, a new study came out that says you can’t blame the cat. Meee-aaahhhh-oooow, what’s that sound? A collective sigh of relief from the ~500 million domesticated cats.
