In order to be considered suitable, the hide must be large enough for the snake to coil up inside it. Some snakes will be satisfied if they can burrow successfully in their substrate. Carefresh has proven itself very successful in this respect and, despite it's unattractive appearance, all the terrestrial snakes I keep love it. A basking spot may be provided by placing a flat rock under the basking light - the rock will absorb heat during the day and allow the snake a preferred are to digest or warm itself. Supplemental under tank heating is a good idea if the animal is from the southern United States or a similar hot area.
Fresh water needs to be regularly available.
Water dishes should be kept clean and disinfected. Some animals require misting to drink - they will not drink from standing water. Cage accessories may contribute to the snakes' mental health if they must be kept for a lengthy period. The most useful additions to most cages are a branch for climbing and the basking rock mentioned above. Some snakes, such as the Green Snakes, are primarily arboreal and require a branch to feel secure.
