"We did one study on cats - and that was enough!" Those words effectively ended my quest to understand the feline mind. I was a few months into writing "Citizen Canine: Our Evolving Relationship With Cats and Dogs," which explores how pets are blurring the line between animal and person, and I was gearing up for a chapter on pet intelligence. I knew a lot had been written about dogs, and I assumed there must be at least a handful of studies on cats. But after weeks of scouring the scientific world for someone - anyone - who studied how cats think, all I was left with was this statement, laughed over the phone to me by one of the world's top animal cognition experts, a Hungarian scientist named Ádám Miklósi.
We are living in a golden age of canine cognition. Nearly a dozen laboratories around the world study the dog mind, and in the past decade scientists have published hundreds of articles on the topic. Researchers have shown that Fido can learn hundreds of words, may be capable of abstract thought and possesses a rudimentary ability to intuit what others are thinking, a so-called theory of mind once thought to be uniquely human. Miklósi himself has written an entire textbook on the canine mind - and he's a cat person.
I knew I was in trouble even before I got Miklósi on the phone. After contacting nearly every animal cognition expert I could find (people who had studied the minds of dogs, elephants, chimpanzees and other creatures), I was given the name of one man who might, just might, have done a study on cats. His name was Christian Agrillo, and he was a comparative psychologist at the University of Padova in Italy. When I looked at his website, I thought I had the wrong guy. A lot of his work was on fish. But when I talked to him he confirmed that, yes, he had done a study on felines. Then he laughed. "I can assure you that it's easier to work with fish than cats," he said. "It's incredible."
