if anyone of you all know when a cat lays on its back and sleeps with paws in the air means they are totally content with things .. of course why it makes me feel good is when i put my hand down on a soft silky furry belly and then they wrap their paws around me and the motor runs (purring) while i rub the tummy and under the neck and all .. this lets me know they are very happy and it makes me feel very happy.
