With skimming the thread I'll agree with KMG for recommending a California kingsnake. I walk around with mine as a neck tie or a sling sometimes. He loves when I fold laundry for some reason.

I'll add African house snake to the mix. They only get 24-30 inches long but really like hanging on glasses and weaving through your fingers. I'll call mine "my little Chinese finger trap" cause it can sometimes be difficult unraveling him from my hand.
