You are very very very wrong.
Are you thinking of king snakes instead of king cobras?
I was gonna say, King Snakes and Indigo's make excellent pets for all the reasons he listed.
These big boys?
Not so much.
Also to quote a snake dude I know "Going from owning a rattler to owning a King Cobra is like thinking you can fly a space shuttle because you know how to operate a prop plane".
