Final answer:
Toxoplasma gondii, a protozoan, is transmitted by cats to humans through cat feces, causing the disease toxoplasmosis. Humans can become infected by consuming contaminated food or water or by handling fecal-contaminated soil or a cat's litter box.
Step-by-step explanation:
Toxoplasma gondii is the organism that can be transmitted by cats to humans through cat feces. This protozoan causes the disease toxoplasmosis and can be transmitted to humans when they consume food or water contaminated with cat feces, or by handling fecal-contaminated soil or a cat's litter box. Domestic cats are the main reservoirs of infection and shed T. gondii oocysts in their feces, which can spread to humans through contact with fecal matter.
