Tight clumping & Anti-bacterial Cat's Best Sensitive was specially developed for sensitive cats and its fine grain means it is particularly gentle to soft paws. The fine granularity also results in the formation of compact clumps that can be easily removed, ensuring economic consumption. Cat's Best Sensitive obtains its natural antibacterial effect from a natural agent which is added to the litter with the green pearls. This supports antibacterial hygiene in the cat litter tray.
