The frequency of these vibrations (20 to 150 Hz) is believed to help bone growth. Other frequencies may have similar effects on tissue.
Cats purr for various reasons: from pleasure when you caress them or scratch them behind the ears; small kittens make a vibrating sound so that their mother cat can understand where they are and feed them;
Many cats carry the purring from a request to their mother into adulthood.
If your cat is comfortable on your lap and receiving attention and affection, purring sounds will appear as a sign of approval.
Body language demonstrates complete satisfaction: the pet's eyes are slightly closed, the tail is moved to the side or curled around the body, remaining motionless.
This frequency has a beneficial effect on human health, activates cell regeneration, and also accelerates the recovery of bones and muscles.
In addition, a cat's purring is an effective stress reliever and normalizes human breathing.
It also turned out that purring also heals the cat itself.
It is also known that purring is a way of communication and a kind of healing agent.
The purring of a cat, or rather the vibrations that occur when purring, have a frequency from 20 to 150 Hz, which, according to some scientists, promotes bone healing and regeneration of soft tissues, including skin.
