I haven’t heard it. But I just saw a testimonial on the site, http://musicforcats.com: “I work at an emergency veterinary hospital. Today we had a patient in incredible pain. He was on as much pain medication as we could give him, but he just couldn’t get comfortable. I put on Rusty’s Ballad for him on repeat, and he’s currently sleeping. Thank you so much for what you’ve created!” Backed by science, this project will be in my interest and subject for deeper studies in my research! Anyone heard and used it?
