Counting in Other Species

Abstract

Nothing causes an argument quicker than a discussion about the intelligence of animals; dog lovers attack cat lovers, horse enthusiasts admire their icon, while pig fans sit back and smile at all the confusion. The question of whether or not animals can count is just as divisive. Some scientists and most pet owners claim that, not only can their favorite pets count, they can add, subtract and, on special occasions, read their masters’ minds. “How did Sparky know I was going for his leash?” says the devoted dog owner. “I could have been getting up to go to the kitchen. But he knew. He jumped up and ran to the front door. The only explanation is that he read my mind.”
