Dogs can do a lot of work through training, but what do they mean to be smarter on their behalf, or are they more willing to please their owners? A study by the University of Oxford found that since the dogs were domesticated 10,000 years ago, their brain-to-body ratio has steadily increased.
Although the time when the cat was domesticated was similar to that of the dog, the similar situation did not occur. This may be because dogs are social animals that require additional brain capacity to handle complex social interactions. The cat’s cerebral cortex (the area associated with learning and intelligence) contains almost twice as many neurons as dogs.
Some experiments have shown that cats and dogs have the same ability to solve puzzles, but this is difficult to detect because cats are not as active as dogs.
