Heh heh. My cat was in my business bugging me (getting between me and keyboard) as she does, and so I played that for her and guess what she did. :=) Sat there a while and then went to her bed and went to sleep. A secret weapon?
Some months ago I found there is a huge subset of youtube dedicated to videos of purring cats. There are even 10 hour long ones. It is relaxing to listen to!
