This is my hypo red tail Colombian boa constrictor and its cage setup.  I have a heating pad on the right side of the cage so it is not under the water, snakes don't like to drink warm water.  The heating lamp provides a basking spot and puts the heat in that side of the cage to about 90 Fahrenheit.  Several hiding spots and opportunities to climb are provided to the animal through the branches, logs, leaves, and the small tree decoration.  I feed it directly in the cage despite the common knowledge to take the animal out when feeding it so it does not become aggressive. However the animal remains docile even when my hands are in the cage, so feeding it directly in its habitat works for me.  It always has water and there is a humidity and temperature gauge in the cage.  However, you cannot not see the humidity gauge as it is behind the leaves.  The heat pad under the cage remains on at all times and the over-head heating lamp goes off when I sleep.  It is important to stimulate the animals natural environment, so turning off and on the light corresponds with the sun going up and down within a 24 hour period.  For a substrate or bedding, I choose mulch made for reptiles because it absorbs water decently and looks fine.  Caring for such an animal can be very easy compared to a dog or any other pet in the aspect that it only needs to be fed once a week as a juvenile and once every two weeks as an adult.
