* They lack the physical capabilities: Cats are not built for flying. They don't have wings, a strong enough skeleton for flight, or the necessary muscles.
* They lack the mental capacity: Flying a plane requires complex decision-making, understanding of aerodynamics, and coordination. Cats, while intelligent, lack the cognitive abilities for such a task.
* They are not trained to fly: Pilots undergo years of rigorous training to learn how to fly and navigate aircraft safely. Cats are not trained in this way.
* Safety reasons: It would be incredibly dangerous to let a cat, with its unpredictable nature, operate a complex and potentially lethal machine like an airplane.
In short, it's just not possible for cats to fly airplanes!
