Interesting cat purring theory
Interesting theory about purring in the magazine from PetPlan. Cats obviously purr when they are happy. They also purr when they want something but solicitation purring has a high pitched element to communicate urgency. (This is cunningly of a frequency similar to a baby's cry.) They also often purr when they are very seriously injured/ill - I mean at death's door. Scientists claim that an injured animal will generally not expend precious energy on an activity not directly connected with survival. One possibility is that they gain reassurance from hearing their own purring which is normally a happy activity. I've also thought that maybe it's because they know that they need looking after and that you are helping them. However I found the following theory an interesting one.
Sound frequencies at the frequency that cats purr at are used by physical therapists. They can improve bone strength, strengthen muscles, ligaments and tendons, quicken healing and lesson pain and swelling. So, your average cat spends a lot of time lounging around purring. Also vets have observed that bone and muscle diseases are rare in cats, and that they're remarkably resilient and recover quickly from injury. Coincidence or not?
