Dogs are smarter than cats. It seems they can’t get a grasp on the concept of cause and effect in quite the same degree that a dog can. Cats could not get their treats in a consistent manner if there was a specific task involved in the getting of the treat. But cat owners know--as do dog owners who will not have cats--that the difference may only be that a cat prefers to be served. Of course, the researcher has practical wisdom. He would not say that dogs are smarter than cats . . . he would only say that cats are "just different."
