This is a common myth that has gone all over around the world. With each region having different myths like in spain they believe a cat has six lives . This myth of cats having nine lives started in egypt as their gods were in feline symbols. Also a cat survived so much extreme weather in fall and winter hence gained that popularity
It's a myth, but cats are very strong pets and could survive a severe blow, locking your self and a cat in a room to kill it may be impossible, they have sharp reflexes and you would end up with a fatal injury
Yes, this is a very common myth. Many people think that this myth is related to the cats ability to always land on their feet. It actually originates from ancient Egypt. There was a cat-headed goddess that was associated with the benevolent factor of a lioness that was said to have nine lives.
These abilities may sometimes seem extraordinary, even supernatural, to us. But the idea of cats having nine lives is no more true than the myth of black cats being lucky or unlucky. Therefore, cats need as much care and attention as any other pet.
