I had to look up toxoplasmosis since it doesn't actually sound like anything good. In typical 4Chan style he's confidently used it completely incorrectly

From the CDC website: "Toxoplasmosis is considered to be a leading cause of death attributed to foodborne illness in the United States. More than 40 million men, women, and children in the U.S. carry the Toxoplasma parasite, but very few have symptoms because the immune system usually keeps the parasite from causing illness. However, women newly infected with Toxoplasma during or shortly before pregnancy and anyone with a compromised immune system should be aware that toxoplasmosis can have severe consequences.

Toxoplasmosis is considered one of the neglected parasitic infections of the United States, a group of five parasitic diseases that have been targeted by CDC for public health action."

After further reading it also appears the only way you would get it from a cat would be by directly handling their feces...
