FACT: It turns out that those cute cat purrs exist in a super-special vibration range that has the potential to be medically therapeutic.
Your average house cat's purr has a frequency between 25 and 150 Hertz. That's interesting because that's also the frequency at which muscles and bones are able to best repair themselves. So cats might be self-healing.
But that's not all: Those super-special, super-adorable cat purr vibrations also exist at a frequency that's good for humans too. The Fauna Communications Research Institute found that every single cat in their study had purr vibrations well within the "medically therapeutic" range (20-140 Hertz).
What does this mean?
Uh, well, that your purring cat can help with bone and muscle repair, pain relief, dyspnea (shortness of breath), and so. Much. More.
