Retrain a Cat to Use the Litter Box
1.Move the litter box to the right location. Cats may stop using the litter box after a scary experience in the area, such as a loud noise or harassment by another pet. They may also dislike the spot you chose after moving the litter box, or moving to a new home. Keep the litter box in a quiet, low-traffic spot where the cat can see people coming. Choose a room with at least two exits so the cat doesn't feel cornered.
2.Play with toys near the litter box. Play with your cat in the same general area as the litter box. Leave toys (but not food) in the room so the cat spends time there and develops positive associations.
3.Keep the litter box clean. If your cat perches on the edge of the box or eliminates right next to it, the box might be too dirty for it. Remove clumps and top up with fresh litter at least once a day, preferably twice. Rinse the litter box once a week with baking soda or unscented soap.
