The purring sound is 25-50 Hz, is that the same as vibration therapy? How cats regulate their own bodies.

Listening to that low rumble, I can feel my own shoulders relax. It's a mysterious sound; when stroking a cat, their owner also feels a sense of calm. Recent research has gradually revealed that this sound may actually benefit the cat's own body.

For a long time, a cat's purr was understood solely as a sign of satisfaction or affection. However, if you observe cats closely, you'll notice them purring when injured, during childbirth, and sometimes even when they're unwell. It's a slightly strange phenomenon to simply dismiss as an expression of happiness.

Elizabeth von Muggenthaler, a researcher at the Fauna Communications Research Institute in the United States, measured the frequency of purrs from domestic cats and several wild felines. The results showed that domestic cat purrs generally fall within the 25 to 150 Hz range. Notably, the 20 to 50 Hz frequency band overlaps with the range used in medical vibration therapy for increasing bone density and relaxing stiff muscles. This means that a cat's body is constantly generating vibrations very similar to those humans produce with machines for healing purposes.

Vibration therapy using this frequency band is applied to post-fracture rehabilitation, arthritis relief, osteoporosis prevention, and even muscle care for athletes. Cats, however, do this without needing to turn on a switch, use electricity, or anything more than their own throats. When you think about it, it's a very energy-efficient and clever mechanism.

Evolutionary Wisdom to Support Long Periods of Rest

Why did cats develop such a mechanism? Researchers hypothesize that the purr is deeply connected to a cat's long periods of rest. Cats spend more than half of their day sleeping or resting. If they remain still for extended periods, their bones and muscles can easily weaken. However, the subtle vibrations from purring may act as an energy-saving self-maintenance mechanism to keep their bodies in shape with very little calorie expenditure. This is the current thinking.

The more they rest their bodies, the more their bodies recover. The quiet rationality of cats lies hidden within that low sound.

If this is the case, then providing cats with a safe and comfortable place to rest for extended periods takes on a meaning beyond mere relaxation. The ability to sleep deeply. The ability to purr soundly during that time. If this becomes a period for the cat to nurture its own body, then the quality of its resting place directly translates into the quality of its health.

The furnya Cat Cellar is a hideaway and scratching post for cats, supervised by an architect who is also a veterinarian. When a cat nestles into the wavy holes reminiscent of a wine cellar, surrounding glances are gently blocked, allowing any unnecessary tension in their shoulders and back to release. The reinforced cardboard is a material that retains heat well, so it seems easy for cats to feel enveloped in their own body heat while curled up. Observing that moment when they lean their back against the wave of the hole and completely relax, my own breathing deepens. We've been receiving more and more feedback from customers saying, "Before I knew it, my cat was spending most of the day here."

We hope that the time cats spend self-regulating their bodies will gradually increase throughout the day. We would be delighted if you would welcome the Cat Cellar into your home, providing a tranquil flow of time where your cat can entrust half its day to a piece of furniture.
