How Can You Properly Maintain a Multi Cat Automatic Litter Box?
To properly maintain a multi-cat automatic litter box, consider the following key practices:

Routine maintenance checks involve ensuring the automatic features are working correctly, such as the rake or sifting mechanism, and checking for any jams or malfunctions. Regularly following the manufacturer’s guidelines for maintenance can help extend the life of the litter box.
