So it seems like my Cat Lady hypothesis linking toxoplasmosis and crazy cattitude that I blogged about in August of 2006 seems to have taken root elsewhere in the scientific community. The New York Times is reporting that the crazy idea may not be so crazy.
“That idea doesn’t seem completely crazy,” Sapolsky says. “But there’s no data supporting it.” [Toxo expert Robert Sapolsky of Stanford]
Not yet. But Jaroslav Flegr, an evolutionary biologist at Charles University in the Czech Republic, is looking into it.
It’s a rather simple leap in logic for anyone who knows the effects of toxoplasmosis, so I’m not surprised that someone else glommed onto the idea. However, I like to think that I may have helped it percolate to the surface, so now it can get some actual scientific study.

With all the evidence of toxoplasmosis links with behavior changes, obsessive compulsive disorder, schizophrenia, depression, and bipolar syndrome, all I can think of is the classic stereotype of the crazy cat lady with 30+ cats.
Is the classic old cat lady just some nutter who hoards cats? Maybe she got toxoplasmosis from her pride of cats, which pushed her more over the edge?
Or maybe, just maybe, she started out just fine with just one or two cats and then got toxoplasmosis, which caused her to become a bit antisocial, and neurotic. The more socially removed she got,the more time she spent with her cats—possibly renewing her infection and increasing the levels of toxoplasma gondii in her brain. Then shortly after, her cats became more of an obsession causing her to collect more and more cats.
Ya know, it really would be in the parasite’s best interest to alter people’s behavior to collect cats and thereby create such a fabulous breeding ground for itself.

p.s. Carl Zimmer’s blog, The Loom, has good article on possible some national personality differences due to differing levels of toxoplasmosis infections between citizens of different nations.
