Captive snakes seldom have the space to prowl, or the need to do so. In the wild, prowling is usually undertaken in search of food, water, a mate or new territory. In captivity all but the latter of these are all brought to the snake. In theory, since each time its cage is thoroughly cleaned most traces of a snake's life are removed, and it is constantly afforded new, albeit small, territory as well.
