I don't understand why people say cobras are more intelligent.
I have 3 friends with King Cobras, and they've all said, there is nothing that they do that is different to any other defensive snakes they keep.
I think just because a cobra hoods, people attribute that to a higher intelligence.
I have snakes that watch me far more intensely than my cobras, for example my Bothrops asper's.
I've been keeping cobras for a few years now, and there is nothing I've noted that would make me think they're more intelligent than any other snake.
Not to mention it took my monocled cobra about 30 minutes, to work out she can't eat food sideways...
