Companion Cat Toxoplasmosis Public Health

Understanding toxoplasmosis transmission from cats, appropriate precautions, and their welfare implications.

Key Facts

Cats are the definitive host for Toxoplasma gondii, shedding oocysts in feces for a few weeks only
Most healthy humans infected show no symptoms
Pregnant women and immunocompromised people should take precautions but need not rehome cats
Daily litter tray cleaning prevents oocyst sporulation and dramatically reduces transmission risk
Cats that hunt are at higher risk of infection than indoor-only cats

Welfare Considerations

Fear of toxoplasmosis is a welfare concern for cats when it leads to inappropriate rehoming or restrictions that compromise cat welfare. Evidence-based guidance that accurately describes risk enables owners to take appropriate precautions without unnecessary welfare costs for their cats.

What You Can Do

Clean litter trays daily to prevent oocyst sporulation and reduce transmission risk
Wash hands after handling litter and before eating
Consult your midwife or doctor for accurate toxoplasmosis risk assessment during pregnancy rather than rehoming your cat
