Lying down, standing, and rolling are relatively easy actions for cats, but to complete these actions following human commands, training is required.

　　Start by training the lying down and standing actions. When the cat is standing, give the command "lie down" and simultaneously use your hand to press the cat down, forcing it to lie down. Then issue the command "stand up" to let the cat stand up. After completing the action, reward it with food and petting. After repeating this several times, the cat will develop a conditioned reflex to the commands "lie down" and "stand up." When the cat forms a relatively solid conditioned reflex to the "lie down" command, you can begin training the rolling action.

　　When the cat is lying on the floor, the trainer issues the command "roll," gently assisting the cat to roll sideways. Repeat this many times. With human guidance, the cat can roll on its own. Upon completing each action, immediately give a reward. As the cat becomes more proficient, gradually reduce the frequency of rewards until food rewards are finally eliminated. After the cat learns an action, give some food rewards after a while to prevent the extinction of the conditioned reflex. (Source：PetsZone)
