When selecting the purrfect cat litter, remember every cat is different. Our top choices in litter selections are here on our site. Whether you pick clumping or non-clumping is up to you. Most cats will go where ever they can... remember in the wild there is no cat litter at all. Thousands of cats end up in shelters or abandoned yearly due to out of litter box experiences. If your cat is going out of the box, think of litter first!
