My cat basically demands that I massage her stomach/intestine area after she does her paws thing on my chest.
She'll knead the bread, get all her muscles stiff and stuff then law down beside me and purrs. She flips on her back to expose the stomach. I end up rubbing 'something', unsure which organ it is but The purring increases 10x while I massage whatever is inside there. Either the stomach or intestines but feels like a stomach.
She's stupidly spoiled. I love giving massages, she she also ends up getting a paw, leg, back, neck and tail base massage. She loves every second of it then weirdly...she has enough and just meows loudly then RUNS and lays down somewhere just out of reach. Weird cat but she's fun
