a snake could definety climbs stairs, it would take hours but its possible. they probably wouldnt go up stairs unless something it wanted was up there.

another thing, if you dont find it before you move check stuff you take out of the house then check the empty house, an empty house would be easy searchin

GOOD LUCK
