Not all cat litter is created equal, and some varieties can actually irritate your cat’s paws, worsen allergies, or make odor problems harder to manage. For example, dusty clumping litters or ones with strong artificial fragrances may seem convenient but can lead to respiratory issues or discomfort for sensitive felines. Understanding which options fall into the category of the worst cat litter types helps you choose healthier, more comfortable alternatives that keep both you and your cat happy at home.
