One of the most meaningful shifts happening right now in animal care is the recognition that sound is not just something animals hear—it is something their nervous system uses to regulate their body and behavior.

For decades, veterinarians have observed changes in animals that could not always be explained by physical examination alone. Animals who appeared physically healthy, yet were vigilant. Animals who struggled to settle in clinical environments. Animals whose behavior shifted depending on their environment.

What we now understand is that sound is one of the primary biological signals influencing the nervous system.

And veterinarians are beginning to see this clearly.
