There were many dangers for cats in the wild, but after people started keeping them as pets, they were brought into the secure and cozy environments cats like. But cats still need a dependable method of burying their waste, so they use litter to cover their tracks. Moreover, for them, it is instinctual to do so to hide their scent from other predators. If your cat does not use the kitty litter or does not cover their business, something may be wrong with the cat or the litter itself. Going to a good pet shop helps you get more professional advice and make your cat happier.
