How toxoplasmosis is transmitted
Cats can shed Toxoplasma oocysts in feces, usually for a limited period after first infection. Freshly passed oocysts are not immediately infectious; they require time in the environment to sporulate. This is one reason daily litter-box cleaning is useful.
Litter-box precautions
If possible, have another household member clean the litter box during pregnancy. If that is not possible, wear disposable gloves, clean the box daily, and wash hands thoroughly afterward. Avoid touching the face during cleaning.
Food and outdoor exposure matter too
Avoid undercooked meat, wash produce, wash hands and utensils after handling raw meat, and wear gloves while gardening or handling soil. Keeping cats indoors and not feeding raw meat reduces their opportunity to acquire new infection.
Should my cat be tested?
Routine cat testing does not reliably tell a pregnant person whether the cat is currently shedding infectious oocysts. Human prenatal questions, testing, and treatment decisions belong with the obstetric healthcare team.
