I have only ever hand fed my Cham and so she pretty much equates fingers with food. A.K.A. that screen door opens and she comes running. One time she actually mistook my finger for a cricket and it scared the ever living heck out of me! Getting bitten felt like strong jaws filled with sandpaper. It didn’t hurt but I wasn’t ready for it . Anyway I have some soft black air line running from my dripper onto pothos leaves and I can get her to drink from it directly like a gerbil (yes totally unnatural). Once she saw my fingers near the water drops she seemed to have a little Ah Ha moment and she now goes right to it for water. I wipe it clean daily. When she’s done with me she gives the chameleon salute and I let her be. I love my smart little buddy and her superhero stretch.
