When choosing a cage keep in mind the great strength of these snakes. Newspaper is the easiest substrate to maintain and a hidebox is a good idea for most species, particularly young ones. The newspaper should always be kept clean and dry. A water bowl big enough for the animal to soak in and heavy enough not to be tipped over is the only other cage furniture needed. This water bowl will also supply necessary humidity for most species.
Some species appreciate branches for climbing.
Some species may require some adjustment to this regime. The easiest method to supply heat is to place a heat pad under one end of the cage or use a light bulb of sufficient wattage to supply the desired temperature. Make sure that this bulb is screened in some way so that the snake cannot burn itself. Boas and pythons feed primarily on rodents and birds in the wild with larger snakes taking larger prey items such as goats and small deer. A diet of mice or rats is all that is needed for captive specimens with rabbits for larger species.
