A cat purring has to be the most relaxing sound there is. I can feel my blood pressure lowering

1. Believe it or not, we have a dog that purrs.

When we got him we had three cats and a couple of older dogs. He made friends with the cats and you would often see him and the three dozing in the sun together. Unfortunately over the years all three of our cats left us for the Rainbow Bridge, but Bennie the dog still makes a noise that I swear is the closest thing to a purr that a dog can manage when he is completely contented with the scratching he is getting. Funniest thing to hear a dog purring!

2. Purring is also healing for the cat, and maybe for you, too.

Scientists have demonstrated that cats produce the purr through intermittent signaling of the laryngeal and diaphragmatic muscles. Cats purr during both inhalation and exhalation with a consistent pattern and frequency between 25 and 150 Hertz. Various investigators have shown that sound frequencies in this range can improve bone density and promote healing.

This association between the frequencies of cats' purrs and improved healing of bones and muscles may provide help for some humans. Bone density loss and muscle atrophy is a serious concern for astronauts during extended periods at zero gravity. Their musculo-skeletal systems do not experience the normal stresses of physical activity, including routine standing or sitting, which requires strength for posture control.

Because cats have adapted to conserve energy via long periods of rest and sleep, it is possible that purring is a low energy mechanism that stimulates muscles and bones without a lot of energy. The durability of the cat has facilitated the notion that cats have "nine lives" and a common veterinary legend holds that cats are able to reassemble their bones when placed in the same room with all their parts. Purring may provide a basis for this feline mythology. The domestication and breeding of fancy cats occurred relatively recently compared to other pets and domesticated species, thus cats do not display as many muscle and bone abnormalities as their more strongly selected carnivore relative, the domestic dog. Perhaps cats' purring helps alleviate the dysplasia or osteoporotic conditions that are more common in their canid cousins. Although it is tempting to state that cats purr because they are happy, it is more plausible that cat purring is a means of communication and a potential source of self-healing.

A few years ago I found other YouTube videos of purring that I'd play if I had problems sleeping. I miss the soothing sounds of my kitties so much. Unfortunately Mr. Duppers developed allergies to them.
