The sound of a cat’s purring brings joy to many of us. This soothing noise is an inherent trait of all felines and often signifies gratitude towards their owner for tasty food and affection. Cats purr like little tractors when they express tenderness and love. Mother cats typically purr while feeding or grooming their kittens.
When answering the question, “Why does a kitten purr?” it’s safe to say they do so to show contentment with their mother’s care or the affection shown by their owner. However, purring isn’t always associated with positive emotions. Cats also purr during stressful situations or while recovering from injuries. Therefore, it’s essential to understand the reasons behind your pet’s purring sounds.
Scientific studies have explored the reasons why cats purr. Purring is a process characterized by the production of rhythmic throat sounds, interrupted by the muscles of the larynx and diaphragm. These sounds occur both during inhalation and exhalation, with frequencies ranging between 25 and 150 Hz.
Why Do Cats Purr?
- When petted: A gentle touch is enough to make a cat start purring.
- Kittens and contentment: Kittens begin to purr as early as the second day of life, signaling their satisfaction and good mood.
- Mother cats: A mother cat purrs in response to her kittens as a way to encourage and soothe them.
- Interaction with humans: If a cat frequently purrs when interacting with its owner, it shows gratitude and contentment. Cats purr when they are petted, given tasty treats, or when their owner returns home.
- Communication with other cats: Cats may purr to signal non-aggression and friendliness to other felines. In the case of an attack, a purring victim may use the sound to signal vulnerability.
- Stress relief: Cats also purr when they are stressed, as the sound has a calming and pain-relieving effect. Experts call this “purr therapy.”
The Effect of Cat Purring on Humans
Scientific studies have proven that purring has positive effects on human health. Independent research shows that sound vibrations from purring contribute to several beneficial processes:
- Healing and recovery: Purring can accelerate the healing of bones, improve bone density, aid tendon recovery, relieve pain, and support muscle restoration. It has also shown potential benefits for chronic obstructive pulmonary diseases (COPD).
- Soothing effect: Purring has a calming effect on humans, making it particularly beneficial for those with nervous disorders.
- Cardiovascular health: Cat purring improves blood circulation in the brain, lowers blood pressure, and helps normalize pulse rates.
- Acupressure effect: When a purring cat kneads with its paws and extends its claws, this action is compared to acupuncture therapy.
Interesting Facts
- Reduced asthma risk: Children raised alongside cats are less likely to develop asthma. Studies suggest that interaction with cats before the age of three boosts immunity against respiratory diseases and asthma. This is attributed to allergens in cat fur, which help build resistance.
- Longevity benefits: Cat owners live an average of 4.5 years longer than those without pets, highlighting the significant emotional and physical benefits of having a feline companion.
