Might sound like something out of science fiction, using the sound of cats purring to heal?

Studies have been done that suggest the sounds of cat purring may aid in healing...

Scientists at the University of California, Davis hypothesised that a cat's purr can be used as a healing mechanism to offset long periods of rest and sleep that would otherwise contribute to a loss of bone density. The vibrations and contractions of a purr work during both inhalation and exhalation show a consistent pattern and frequency around 25 Hz; these frequencies have been shown to improve bone density and promote healing in animal models and humans.

Dr. Lyons, one of the scientists in this study, suggests that this finding may be applicable to astronauts during extended periods in zero gravity. Bone density loss and muscle atrophy is a serious concern for astronauts during extended periods at zero gravity. Since during these periods musculo-skeletal systems do not experience the normal stresses of physical activity, including routine standing or sitting, which requires strength for posture control, exposing these astronauts to sound frequencies similar to those of a cat's purr could counteract the deteriorating effects of low gravity

Another theory states that purring triggers a cat's brain to release a hormone which helps it in relaxing and acts as a pain killer.
