Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to train a cat [title] Put the litter box in a quiet location. [step] Cats prefer to relieve themselves in a peaceful location without a lot of action or loud noises in the background. However, cats also do not like having a litter box that is too far out of the way.

Ending1: It may be an exercise room or a busy breakfast room, since cats do not like going out of their box at all. Look into getting your cat a box in the living room, or you can move the litter box into a neutral location, such as a different bedroom. Ending2: [substeps] Make sure your cat can physically access his litter box. Do not put the box on a high shelf or an otherwise difficult to reach area if your cat is old and has trouble jumping or climbing. Ending3: [substeps] You may get about 15 to 30 minutes of total quiet time per day by putting the box out of view of any children or other animals. The quiet time will also help make your cat feel more at home, as it will also gradually decrease noise levels in the litter box. Ending4: Therefore, it's a good idea to place the litter box in an area where there is no noise to distract them while training the cat. [substeps] Look at carpet lying on the floor and walls around the litter box.
