The "Half Ledge" Repti-Ledge Feeder is designed for arboreal reptiles that climb and forage for food in nature (e.g. geckos). This unique feeder secures to any interior wall of your reptile's terrarium, allowing them to climb and feast at will. The Repti-Ledge features ultra-durable acrylic construction, and comes with a powerful suction cup to hold it firmly in place. It also includes two 1.5 oz disposable feeder cups to hold fresh food and water. Super easy to install, remove, and clean! Additional replacement cups sold separately.
