I tried this product on a Female Durango that refuses to eat unless scented.
I tried a few different approaches.
1. I tried thawing the pinky with a couple of drops of marker in the water.
2. I placed the marker directly on the food item after washing and drying the pinky.
3. I tried the bait and switch. I offered her a real lizard scented item then pulled it away and switched it immediately with the chemical marker item. She refused it.
4. I then tried scenting with real lizard that she accepted immediately followed by the chemical marker item and again refused that item.
Not real impressed with lizard marker. On the other hand, I may have one very picky Durango……Dann
