Litter we use

World’s Best Cat Litter is a clumping cat litter that is easy to scoop and forms into small, tight clumps that don’t crumble when you try to remove them from the tray. This litter is lightweight, made from sustainable corn with no chemical additives, ensuring that is safe for humans, cats and the planet. It can also be easily flushed and has been tested to ensure it is safe to pass through both sewage and septic systems, saving you visits to the bin.
This World’s Best Cat Litter is also 99% dust-free, making it ideal for allergy sufferers. It helps to trap odours and keep them contained within the litter, keeping your cat’s litter tray and your home fresh and free from unpleasant smells.
