Aparently bones heal faster in cats than in other animals. Cats also have half the cancer rates that dogs do. Veterinarians and scientists believe it has to do with the healing effect of purring, which also may fuel the myth about cats having nine lives.
I also found comments about laying near a purring cat to cure migraines, and cats sensing illness and laying down at the affected area. One person even mentions their self-winding watches will stop when a cat lays purring near it for a long period of time when watching TV.
Perhaps those crazy-cat ladies aren't so crazy after all. I suggest we fund a study testing bone density and the rates of osteoporosis in people who sleep with their cats.
I also suggested my co-worker should get a cat to help her knee ligaments to heal faster, rather than her e-stim machine. She looked at me like I was crazy. But I think I've only started to touch on my inner crazy cat lady now that I have an excuse!
