If a cat is infected with toxoplasmosis, the first symptom may be a recurring, prolonged cold-like illness, such as fever, recurring low-grade fever, respiratory problems, sneezing, and runny nose. If toxoplasmosis is suspected, a veterinary test can be performed, such as a test strip to check for antigens or a PCR test. These are relatively accurate tests that can determine whether a cat is infected with toxoplasmosis. If the owner notices that the cat frequently experiences cold-like symptoms or recurring low-grade fever, then it is necessary to have it tested for toxoplasmosis at the vet to determine if an infection is present.

Toxoplasmosis is mainly excreted through cat feces. Of course, it requires a specific environment to cause infection in humans, so there is generally no need to panic about pet cats; just maintain regular cleaning and disinfection.
