My syrian Star is the same with that one, she totally ignores it. My other syrians have ran off with them and shredded them to get to the treats
So no, you are not doing anything wrong. I do other ones instead for Star, like cut biggish holes in 3 -5 places in a tube, stuff some food in the middle and add some bedding in both ends. Or, make smaller holes in the sides of a tube, poke food in the holes so they stick out, place in cage upright, submerge the bottom into the bedding so stand uprights, and fill the rest of the tube with bedding. I'm actually in the middle of editing a video on this
