Every cat lover thinks their cat is the smartest cat in the world, and they’re probably right. That’s because cats re good at manipulating their humans into thinking they’re in control but the cat’s really the one in charge.
Still if you insist on wanting a cat that’s smart than most people, you might consider getting one of the smartest cat breeds available such as a Bengal cat or a Scottish Fold cat. That way you can have a great cat and a smart one that can outwit you whenever it wants, which is the way most cat owners live with their felines anyway.
