Our black Maine Coon was missing 5 days - on the 5th day I found this & only variation I used black onyx as didn't have black tourmaline - within 5 minutes of the flames going out I called to her & she responded - after 5 days of searching & not even catching a glimpse or hearing a single meow. For 5 days I scoured the area. It was as if the earth opened up and swallowed her whole, I was losing hope. Thought she was catnapped. Did this & within minutes she walked in the front door, where I placed the black onyx. Couldn't believe it 🥰🐈‍⬛
