As a cat lover, I am naturally skeptical of any article that claims such adorable creatures could cause any harm to humans, but the idea that cats carry a parasite that alters human behavior is pretty fascinating.
The parasite is called Toxoplasma gondii, and it makes rats unafraid of cats. Humans can also be infected with the parasite, leading me to first think of crazy cat ladies (like this Ukrainian one) who love their cats more than other humans, but then the article claims a link between Toxoplasma and schizophrenia, bringing whole new meaning to the term CRAZY cat lady.
As the blog where the original article was posted has disappeared, you can read the entire article “The Return of the Puppet Masters” after the jump. (Thanks to Tom D. for the tip!)
