Can cats see ghosts? This is one of those questions that are actually impossible to answer. The reason is that there is no scientific way to test or prove whether cats can see ghosts. Can cats see ghosts is a question that if you ask a hundred people the same question you are likely to get at least fifty different answers.
When you talk to cat owners about this question, the owners that believe in ghosts will say that their cat can see ghost. Those that do not believe in ghost will tell you that their cat is exhibiting natural behavior. This brings us to another question, why do people even think that their cat can see ghosts.
The answer to this is two-fold; first, the cat has a reputation for being somewhat of a mystical creature. They have had this reputation for centuries. Secondly, the cat gets this reputation because of some of their behaviors; these behaviors include some uncanny skills. First, a cat will just stare into space, suddenly run off, or begin hissing. This is the main behavior that causes people to claim that their cat is seeing ghosts.
Some of the other uncanny skills that a cat possesses that lead humans to wonder, can cats see ghost. Cats are silent when they move, which makes some people believe that cats are supernatural. Cats never run into objects, they always land on their feet, they can set motionless for hours, and their glowing green eyes all give humans a reason to claim that cats are supernatural beings, therefore, they must be able to see ghost. Admittedly, cats are far more sensitive to, and aware of their surroundings than humans, but this does not prove that they can see ghost. On the other hand, there is no proof that they cannot see ghost either, it all comes down to what you believe.
