Who is smarter – the cat or the dog?

Brace yourselves cat people, a new study claims DOGS are smarter! 

Researchers, who charted the evolutionary history of several mammals' brains, say they’ve revealed a link between social interaction and brainpower. Because dogs had more social tendencies, their brains and skulls got bigger over time. The brains and skulls of cats hasn’t changed much, due to their less social and aloof dispositions. 

The study also says that dogs are skilled at social bonding which further stimulates their brains. That rule doesn’t apply to most cats, who prefer napping, hunting and grooming to pleasing others.
