One protozoan, Toxoplasma gondii, reproduces inside the belly of a cat, and is then excreted by the feline. One way it begins the cycle again is to infect a rat passing near the excrement. Toxoplasma gondii reprograms the infected rat to love cat urine, which to healthy rats is a predator warning. An infected rat wallows in cat urine, offering itself up as an easy meal to a nearby cat. This way, the parasite again enters the cat’s stomach, reproduces, and is expelled in the cat’s excrement—and the cycle continues.”” [Sam Quinones](https://sms4smile.com/quotes/author/sam-quinones/) ## About This Quote This interpretation was drafted with AI assistance.
