Burying Their Droppings Is Instinct
Out of instinct, cats bury their droppings after using the litter box. This is because, in the wild, they don’t want predators to catch their scent or for other cats to kick them out of the group for putting others at risk.
Weirdly enough, if your cat is not covering up their business, then there might be something wrong. It could be something materialistic, such as the cat not liking the type of litter or box. Even the location and accessibility could factor into why they’re not covering up their droppings. Others think it could be related to stress, anxiety, or even issues with the cat’s health.
