Have you ever wondered why cats purr? It’s one of their most distinctive behaviours, but there’s more to it than just contentment. Scientists and pet experts have found that a cat’s purr serves multiple purposes, from communication to healing.
Why Do Cats Purr?
Most people associate purring with happiness, but cats also purr when they are stressed, in pain, or even near the end of their lives. It’s believed that purring helps to soothe them in difficult situations, much like how humans may hum to calm themselves. Some cats will also purr when they are hungry or seeking attention from their owners, using this sound as a form of communication.
The Healing Power of Purring
A cat’s purr vibrates at a frequency of 25-150 Hz, which falls within a range that has been found to promote healing in bones, reduce inflammation, and even lower stress levels in humans. Studies suggest that these vibrations may encourage bone regeneration, making purring an inbuilt form of self-repair. This explains why spending time with a purring cat can feel so relaxing!
Purring as Communication
Some cats develop a special type of purr called a ‘solicitation purr,’ which blends with a meow to grab human attention—usually at mealtime! Studies show that this type of purring is similar in frequency to a baby’s cry, making it hard for owners to ignore. Some cats use their purr to comfort their humans, lying close and purring when they sense distress or sadness in their owners.
Why Do Cats Purr When They Sleep?
Many cats will purr as they settle down for a nap. This could be their way of self-soothing, keeping themselves calm while they rest. It may also be a sign that they feel completely safe in their environment. Some cats will continue purring even in deep sleep, suggesting that the rhythmic vibrations have an ongoing calming effect.
Can Purring Benefit Humans?
Research suggests that the vibrations from a cat’s purr can have therapeutic effects on humans, such as:
- Lowering blood pressure – Studies have shown that cat owners tend to have lower stress levels and a reduced risk of heart disease.
- Reducing stress and anxiety – The rhythmic nature of a purr can create a calming atmosphere, similar to meditation or deep breathing exercises.
- Helping with insomnia – A purring cat can provide a soothing background sound that helps some people fall asleep more easily.
- Promoting wound healing – Some research indicates that frequencies in the purr range can promote the repair of soft tissue and bones.
Next time your cat curls up and purrs, know that they’re not only expressing their emotions but also sharing a natural form of comfort and healing with you. Isn’t that amazing?
