They could poop inside the box but digging it out by mistake when trying to cover it.

If you have more than one cat, one might be stressed by the other(s), especially if new.

Cat might be too old or too small to climb into the box, or not feeling well.

Some cats are assholes and doing it on purpose to show you they are not happy (is the box clean?).
