There are many types of cat litter. Certainly you would need to find a product that clumps, is easy to retrieve from the cat litter box and has low dust. Cats can have ‘litter box aversion’, so the priority would be to find something kitty likes so inappropriate elimination does not occur. For a specific recommendation please call one of our veterinarians. If your cat is not using the litter box, you should contact our office immediately.
