I love both cats and dogs
I have come to understand that when cats purr they are infact re-balancing there bodies, self healing if you will, Resonance vibrational frequency.
An old friend of mine had a brain tumor removed, sent home to recover. Her 3 cats sensed she was ill and laid around her pillows near her head, for 2 weeks, purring the whole time, Doctors were amazed at her seemingly quick recovery.She is convinced it was due to the help of her cats.
Peace always
