The Exo terra dripper plant is a realistic plant that was designed to meet the watering needs of tree dwelling reptiles and amphibians like e.g. Chameleons. arboreal reptiles generally do not recognize motionless sources of water; instead they drink from moving dewdrops and raindrops while foraging in the forest canopy. the Exo terra dripper plant supplies a continual supply of cascading water droplets, attracting even the most reluctant reptile to drink. Regular access to a recognizable source of drinking water helps prevent illnesses related to dehydration and will improve your animal's overall health.
