text: Hey Hulali.  Those species you listed don't "infectiously spread" toxoplasma.  If they are infected, the parasite will either asexually multiply, cause disease and kill them or encyst in tissue and not result in disease symptoms.  If, and only if, they are eaten by something else (and not cooked) can they spread toxo and it would only be to the individual that consumed the cyst.  The cysts or protozoa die quickly when they are exposed to the environment when the animal dies and rots.  So for most larger mammals and animal in the Hawaii toxo runs into a dead end if it infects them.  Cats, who collectively shed billions of oocysts (eggs) into the environment can infect any bird or mammal that consumes it and each animal is differently susceptible to the disease.  Toxo may enter the marine ecosystem when there are sewage spills but that will depend on the level of treatment and if infected cat litter was flushed.  Humans don't shed toxo oocysts, so it doesn't matter if there is human poo
