From The Tribune:
Toxoplasma gondii is a parasite that can infect warm blooded animals, including rodents and even us humans. It can cause disease, known as toxoplasmosis, but most infected humans do not have any symptoms.
Mild cases have flu-like symptoms, and more severe symptoms include organ damage and can be especially dangerous for pregnant people. If you’re pregnant, avoid scooping cat litter if possible, and visit the CDC page on toxoplasmosis if you want more information.
