Have you ever wondered if animals like music? The animals at an animal shelter seem to enjoy it. Through a program called Wild Tunes, funded by a Houston-based nonprofit by a 10-year-old animal lover, volunteers have been playing music at the shelter. Animals at the zoo love it as well. The Colorado Symphony Orchestra partnered with the Denver zoo a few years ago to host a successful private event! Find out more about these animal adventures with sound here and here.
