That’s actually my favorite parasite! Toxo really wants to live inside a cat’s digestive tract, so much so that, when a rodent gets it in their blood, the baby toxos produce cysts in the brain (and liver and muscles) that hypnotize the rat into being attracted to cat poop. This leads to the rat hanging around where cats poop, and therefore getting eaten by the cat, and ending up happily back inside the cat’s GI tract.
