Some cats prefer using different types of litter. Whilst some like clumping “scoopable” litters, others may prefer a softer, finer grain – especially indoor cats that have softer paw pads, and older cats with arthritis. If you have to change the litter you use, do it slowly so that it doesn’t come as a surprise to your cat and put them off. Also avoid scented litters or tray liners, as they can upset your cat’s sensitive nose and put them off using the litter tray. Follow the instructions on the litter packing for recommended depth of litter; making sure that your cat has enough to dig with. Placing newspaper underneath the tray can help to catch any loose debris.
