Cat-dependent diseases cost Australian agriculture at least $12 million annually. The sheep industry
is the worst impacted. Four pathogens Toxoplasma gondii, Sarcocystis gigantea, S. medusiformis and Toxocara cati were introduced to Australia when cats were introduced here, because they depend on cats for part of their lifecycle. All of these pathogens produce eggs that are passed in cat faeces. The eggs persist in soil, pasture and water, and are subsequently ingested by stock.
These pathogens cause a range of animal health impacts including spontaneous abortions, still births, neonatal deaths and visible cysts in meat, which reduce its saleability.
