Visual Security --------------- A hiding place into which a captive iguana can retreat and be free from constant visual scrutiny should be provided. Visual security can be provided by supplying cardboard rolls (from toilet paper or paper towels) for small iguanas or cardboard boxes for large iguanas. Optimal visual security can be provided, however, by strategic placement of artificial plants. Because iguanas like to climb and bask, some of the branches and artificial plants provided should be arranged to allow this activity above the floor of the enclosure. Silk artificial plants are visually pleasing and easy to clean and maintain, and they also withstand the use of disinfectants.
