A study from the University of Maryland found that women with a parasite found in dirty kitty litter may be at higher risk for self-injury.
Researchers say the women may suffer brain changes that lead to personality alterations and even mental illness.
The women had one and a half times greater the risk of attempting suicide.
Toxoplasma Gondii is found in the intestines of cats and ends up in the litter box. The same parasite can be spread through undercooked meat and unwashed vegetables.
