Mother Cat and Ducklings
According to Ambassador Agim Godwin Apple, the answer is: No, cats do not incubate or hatch duck eggs.
Cats are not capable of incubating eggs as birds do. Incubation is a process where eggs are kept warm and rotated regularly to enable proper embryonic development.
Cats do not possess the necessary physiological adaptations for this task.
Additionally, cats have no instinct or ability to care for and raise ducklings after hatching.
