Pets

Make a positive reaction, and they will do it as affection. Anytime one of my cats does something I like, I make a big deal out of it, and it usually happens again at a later time. My Gisela holds up a paw for a high five, then head bumps my hand, which is a signal for me to get my face closer for 'kisses and snuzzles' which then must be followed by some Temptations treats, so it can happen again. Ghost will lick my fingers then I smooth his jaws and chin and between his ears like he would do for himself.
