Interesting finding, to be sure, but how does one even begin to test a theory like this? Why in the world would anyone posit that kitty litter could be related to suicide attempts?
As it turns out, about one-third of the population is walking around right now with latent toxoplasma infection. Most people will never know they have it - and most will not attempt suicide as a result of it. But the presence of T. gondii among women who attempted suicide raises interesting questions.
I knew they would eventually find a way to kill us all off.
