evidence: Toxoplasmosis is a widespread infection caused by the parasite Toxoplasma gondii, affecting both humans and animals around the globe. While cats are the definitive hosts of this parasite, meaning the parasite completes its life cycle in them, it's important to understand the implications for both feline and human health. Despite its prevalence, many cats with toxoplasmosis show no symptoms, but the infection can pose significant risks, especially to certain vulnerable groups. [...] In cats, toxoplasmosis is often asymptomatic, but when symptoms do occur, they may include fever, loss of appetite, and lethargy. In severe cases, especially in kittens or immunocompromised cats, the infection can lead to more serious issues like pneumonia, neurological symptoms, and even death. Humans infected with T. gondii are usually asymptomatic as well. However, the infection can cause flu-like symptoms such as swollen lymph nodes and muscle aches. For immunocompromised individuals and pregnant women, the infection can be much more serious, leading to complications such as neurological damage or congenital toxoplasmosis in newborns, which can result in vision impairment or other long-term health problems.
