Enclosure and Space Requirements -------------------------------- As a general rule, snakes require relatively little space because of their limited and nonexertional activity. Generally speaking, the size of the enclosure should allow inclusion of certain required items (discussed below) and still allow the snake adequate space to stretch out and move about. Snakes will use both the horizontal and vertical space within their enclosure if provisions are made for this activity. Aquaria or other similar glass or plexiglass-lined enclosures are usually most suitable because they allow optimum visualization of and safety for the occupant(s), and help to maintain desirable environmental temperatures and generally high relative humidity levels. Wire-lined enclosures may afford adequate visualization of the snake but certainly cannot contribute to the maintenance of desirable environmental temperature and humidity levels. Furthermore, such enclosures promote injuries to the rostrum (nose and surrounding tissues) as snakes repeatedly attempt to escape through the wire mesh. Any enclosure used must have a secure top and be escape-proof. All hinges and locks should be secure. All snakes are potential escape artists and many (especially the California King snakes) can escape from almost any apparently secure enclosure.
