A purr is a sound made by all species of cats. The mechanism by which cats purr is ambiguous. This is partly because the cat has no unique anatomical feature that is clearly responsible for the sound.
House cats may actually be contributing to our physical well-being. When a cat purrs within a range of 20-140 Hertz, nearby humans may be therapeutically benefiting from these vibrations. Purring has been linked to lowering stress, decreasing symptoms of Dyspnoea, lessening the chances of having a heart attack, and even strengthening bones.
It seems that our own animals have the ability to relieve us of our troubles, or at least make our worries seem less important. The bond between pets and their owners may never be fully understood but it’s nice to know having a furry confidant around can add years to our lives.
