Are Dogs Smarter than Cats?

Scientists says cats are not as clever as we think. The thought processes of 15 cats were tested by attaching food to the end of lengths of string and observing whether they could figure out that pulling the line brought the treats closer. The cats had no problem with tackling single pieces of string. But when faced with two options, experts discovered that unlike their canine counterparts, cats were unable to consistently pick a baited string over a dummy.
