I agree with franky. The BP won't be as tolerant as a corn or rat snake when it comes to husbandry. Keep in mind the things mentioned such as "lap snake" is true for the most part but then each individual snake can throw you a curve ball too. Our BP is the most roving of our critters. Constantly on the move. Our Colombian turns out to be the "lap dog". You could literally take Biggles out and nap next to him for hours and he'd still be there.

But I'm digressing from the OP. Out of your original list if looking for a lap snake then I'd probably shoot for the BP. Living in AZ we have had tons of Gopher (Bull) snakes and quite a few Kings and they def are not lap snakes.
