When it comes to retraining cats, the best kind of litter is often one that is unscented and made of natural materials. This will help keep your cat’s environment clean and comfortable while also protecting them from potentially harmful additives or chemicals. Clumping litters are generally better for retraining cats since they make it easier to spot areas where accidents may have occurred so you can more easily identify which area needs more attention during the retraining process. Additionally, clumping litters tend to be more absorbent than non-clumping varieties, making them better at controlling odors as well as preventing messes from spreading throughout your home. When choosing a litter, always select one with minimal dust since this can cause respiratory issues in both humans and animals if inhaled over time. Overall, an unscented natural clumping litter should provide the most benefits when trying to retrain cats successfully!
