Ever Wonder Why Your Cat Purrs

Now I know you have asked yourself more than once why your cat purrs, right.

Well I’m afraid I can’t personally answer this question but I found someone who can.

Residing in California I am very proud of the University of California School of Veterinary Medicine. I have personally know people with pets that couldn’t be cured. After visiting UC Davis their pet was either cured or helped in some way.

Leslie A. Lyons, an assistant professor at the School of Veterinary Medicine at the University of California, Davis, explains.

Over the course of evolution, purring has probably offered some selective advantage to cats. Most felid species produce a “purr-like” vocalization. In domestic cats, purring is most noticeable when an animal is nursing her kittens or when humans provide social contact via petting, stroking or feeding.

Although we assume that a cat’s purr is an expression of pleasure or is a means of communication with its young, perhaps the reasons for purring can be deciphered from the more stressful moments in a cat’s life. Cats often purr while under duress, such as during a visit to the veterinarian or when recovering from injury. Thus, not all purring cats appear to be content or pleased with their current circumstances. This riddle has lead researchers to investigate how cats purr, which is also still under debate.

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.

Now I’m not so sure I can agree with his “purring when under stress” statement. I think you will agree that what a cat does under stress is try to get away from the stress situation any way possible and that doesn’t include purring.

Just a reminder for all cat owners, you don’t want to take your cat anywhere without a cat carrier. While we have a tendency to call them “dog carriers” and “dog crates” they work just as well for cats as dogs. We just don’t need to use them as often. Consider a “cat carrier” for your special furry friend and stop using those cardboard carriers. A vist to this post will show you why.

Bill Beavers is a pet lover and is providing products enhancing quality of life for you and your pets. Be sure to visit my website where you will find the best in high quality pet carriers, dog crates, pet strollers and much more. Every pet should have their very own dog crate. It’s their personal “den.” Pet Carriers and Pet Strollers provide opportunities for family and pet fun. We have Cat Condos and Cat Trees too!
