Cats may be cute, but they may not always be friendly. Sometimes you can pet a cat and suddenly have the cat turn on you and lunge at your hand, biting or clawing your skin off until blood drips down your damaged limb. Why do cats do this? Because they can.
The other reason why cats might suddenly turn on people may be because cats don’t know how to communicate otherwise, much like children. As a general rule, pay attention to your interaction with a cat and you’ll likely catch signs that the cat wants you to go away. Remember, just because a cat is fluffy and cute doesn’t mean it wants you to touch it.
