I use the shooting gallery feeding station which does a great job at containing crickets and other feeders. All of my chameleons have learned that’s where the food is. Sometimes though, a couple don’t notice that I’ve put their bugs in it. Usually I’ll just run my fingertip on the outside screen of the feeding station to catch their attention, which works 9/10 times. My male veiled can be on the opposite side of his double wide enclosure (3+’ away) and picks up on the vibration of running my finger on the screen and he comes running over for food.
