It’s a sound everyone has heard at some point. Even if your cat is the sweetest little cat on the planet, if she has ever felt threatened or needed to send a warning to someone (feline, canine or human), she has probably hissed at some point.
Hissing may seem like a comical sound for a cat to make but trust me, your cat isn’t viewing it with any type of sense of humor. If your cat is hissing then she feels there’s an immediate threat.
How Do Cats Hiss?
The hiss is created when the cat forces a burst of air out through her arched tongue. If your face is close enough to the cat when she hisses, you can actually feel the air being shot out through her mouth (but please don’t ever be close enough to experience that). She will pull her lips back as well and the ear position will be flattened against the head. Additional body posture typically accompanying the hiss includes arched back with piloerection of haircoat.
