This is straight off of MSN's news feed. Scientists have determined with concrete evidence that dogs are smarter than cats. A dog's problem-solving abilities are equivalent to a human 2-year olds. The average cat... sorry Chip.. it only operates with the cognitive capacity of an 18-month old. At 2 years of age Tierney knew all her ABC's; had memorized her favorite books, could count to 100; and was totally potty trained. I knewed I be smart.
