There are many reasons why cats don't bury their feces. Generally, cats are very clean animals, and if the litter box isn't cleaned regularly, the cat may stop burying its feces due to the dirty environment. If a cat didn't learn to bury its feces from a young age, it might be because its mother didn't teach it this skill, or it was rescued from a harsh environment. In multi-cat households, cats may use not burying their feces to assert their territorial dominance.
Other factors that may cause a cat to refuse to bury its feces include the location and size of the litter box, the quality of the litter, and a poor feel underfoot. If a cat exhibits other unusual behaviors while refusing to bury its feces, such as frequently entering and leaving the litter box, making unusual noises, or changes in the frequency or manner of urination or defecation, it may indicate that the cat is suffering from illness or pain.
