My friend trained her cats to sit on command, give her their paw, and to come when called. She trained them when she was 12 and with a lot of work, patience, and cat treats, the cats got the hang of it. She was only going to train her kitten but then her sister's cat came over and saw the kitten was getting treats so the cat began to do the tricks too. The cat can even roll over on command. It's crazy.
