Since cats have shown to have a very good sense of hearing, it makes sense that the right music can help mellow your cat.
The best way to see what your cat prefers is to experiment. Try playing different types of music and see what happens.
A popular song compilation aimed to keep your feline friend content and relaxed is Relaxation Music for Dogs and Cats.
Watch the way your cat communicates with the music you’re playing and adjust it to make him/her more happy.
