Training your cat requires patience. It is helpful if you determine what behavior comes most naturally to them. For Lucy, she occasionally would sit up with her front paws held down so we started to give her the word command SIT UP and reward her. Many cats can be encouraged to sit and “plant their butt”… . Domino in his video first made a mistake and “sat up”, but then remembered what I wanted. Clementine was good at “give me paw” — this came naturally to her, but after rewards and reinforcement, she learned to associate the verbal command and perform the “trick”.
