Jen,
I loved the pictures of positioning. I have to admit it I was touched. I may be a crusty old man but I get purr therapy every evening. IT WORKS!!! Our little furbaby Emily waits for me to come to bed each evening. She cuddles up beside me and the purring begins. Now that's stress relief!!!!
Actually, I think just looking at big calm cats like our monster-sized Dillon reduces blood pressure.
