"Crazy cat lady" isn't just a stereotype.  It's a very, very real thing.  But some scientists at the University of Vienna in Austria wanted to figure out why:  Why does it always seem to be women who go insane and have 80 cats, and not men?

So they analyzed the interactions between cats and owners through a series of tests, and came up with a conclusion:  Women and cats tend to be more in sync because women subconsciously pick up and give off subtle bonding signals.  Men don't.

Manuela Wedl co-authored the study.  She says that women tend to really interact and connect with their cats, quote, "[so] the cats approach female owners more frequently, and initiate contact more frequently.  "Female owners have more intense relationships with their cats than do male owners."
