@marcozehe it's such a comforting and calming sound. If I have a bad day all I need to do is pet a cat and I feel much, much better immediately.
@talon Yes, or lay on your back and have her lie down on your chest and stomach and purr. That often helps me when I'm having a bad day.
@talon Ooooh that cat is definitely enjoying herself! She sounds very much like one of mine. That one can also purr this deep.
