A small subset of suicide attempts may be linked to an infection that starts in the litter box. A new study suggests an association between Toxoplasma gondii and suicide attempts among women. 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?
