From a young age, cats have a strong instinct to void in sand or soil. Typically, cats dig to prepare a shallow hole. More digging usually follows to cover its waste.
Cats exhibit a wide range of normal behaviors relating to elimination.
Some normal cats do not cover waste, while other enthusiastically dig before and after voiding. To encourage kittens to use the litter, gently place the kitten in the pan soon after each meal. If the kitten has had an accident outside the box, simply place the mess inside the box to help the kitten make the desired association. Punishment is never necessary, as kittens usually learn quickly. Avoid disturbing your cat while it is using the box and never punish it for any reason when it is near the box.
