Breeds of the cat species that could possibly kill you in one way or the other. However for this list I'm only including breeds of cats other animal breeds like dogs will not be included for this very reason.
The Top Ten
1LionThe lion is one of the big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa.
Chances are it would tear you limb from limb.
That picture says it all...
3PantherThe cougar, also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas.
Just as deadly to be honest.
4TigerThe tiger is the largest cat species, most recognizable for their pattern of dark vertical stripes on reddish-orange fur with a lighter underside.
Do I really need to explain why for this one?
5CheetahThe cheetah, also known as the hunting leopard, is a big cat that occurs mainly in eastern and southern Africa and a few parts of Iran. The cheetah is the fastest land animal, able to run up to 75 mph and can accelerate from 0 to 60 mph in just 3 seconds
They would kill you faster than you would be able to run away from them.
6Mountain LionThe cougar, also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas.
Quite deadly I'll add.C
7SingapuraThe Singapura is one of the smallest breeds of cats, noted for its large eyes and ears, brown ticked coat and blunt tail.
This Singapore cat is very dangerous and best to avoid.
8SphynxThe Sphynx is a breed of cat developed through selective breeding starting in the 1960s, known for its lack of a coat, though it is not truly hairless.
Not as deadly as other breeds so it isn't as high.
9SiameseThe Siamese cat is one of the first distinctly recognized breeds of Asian cat. Derived from the rtgs: wichianmat landrace, one of several varieties of cat native to Thailand, the Siamese became one of the most popular breeds in Europe and North America in the 20th century.
Only if you harm these cats will they really be lethal...
Somewhat aggressive but only to people that don't take care of it or aren't their owners.
