Transitioning Your Cat to an Automatic Litter Box
A gradual, stress-free introduction is key to success.
Step-by-Step Transition Process
Week 1: Introduction & Familiarization
Place the new automatic box next to the old, familiar box.
Keep the unit turned off and unplugged.
Allow your cat to explore it freely. Add a handful of used litter from the old box to transfer a familiar scent.
Week 2: Supervised Operation
Plug in the unit and turn on the automatic function.
Closely monitor your cat's reaction to the sight and sound of a cleaning cycle.
Ensure your cat is not startled or fearful.
Keep the old litter box available and in use.
Week 3: The Full Transition
If your cat is using the automatic box consistently and calmly, you can remove the old litter box.
Continue to monitor usage and behavior.
Praise and reward your cat for using the new box.
Be prepared to backtrack a step if any issues arise.
Troubleshooting Refusal:
Immediately return to the previous successful step in the process.
Experiment with different types of litter (if compatible).
Manually keep the automatic box impeccably clean during the transition.
As a last resort, consider a different model with an alternative cleaning mechanism.
