After my first stem cell transplant I spent several months at home recovering. A lot of that time I was pretty sedentary and spent time on my couch reading or watching TV while my body healed. My two cats, Martha and her daughter, Stella, took turns lying on my chest purring. Each would spend 30 or 40 minutes on me, and when one would get off my chest, the other would quickly resume the position. I called it my “feline therapy.” Since that time I have read articles that the feline purring is at a frequency that actually has healing properties. I believe Martha and Stella instinctively knew I needed special attention and the healing their special therapy offered me.
