I seem to have a knack for finding a cat or dogs sweet spot and if they are in need of a pat or ear scratch they know I'm the guy that can satisfy them. Cheers!
I just read an article about scratching a dog's ears to trigger off their feel good vibes, cats love to be stroked under their chin. If you're interested there is a book called The Tellington Touch which is all about calming animals by making little circles on their bodies with your fingers. That's the basics, obviously a lot more to it but I have tried it on our dog who is afraid of storms and it does calm her down.
