Why do Cats Hiss

Many people have the misconception that cats hiss because of aggression or hatred but they actually hiss due to fear. When they hiss, they will normally bare their teeth, flatten their ears to their head, fur standing on end, and back is arched. This is normal behavior for a cat. Not only will they hiss because of fear but also because they are upset about something or they feel threatened. Hiss is not aggressive behavior but if they are hissing a lot, then there is something wrong, or your cat is trying to tell you something.

Among animals, mimicking another species is a survival tactic. In most species, from horses to humans the sound of the snake’s distinctive noise get a hair-raising feeling. The cat borrows the snake’s vocal sounds hoping they can get the same reaction from whatever is bothering them. They hope that the hissing will be enough to keep them safe.

It is not something they can control because they will hiss when they feel threatened or scared. This is a common cause of your cat hissing.
