Why Do Cats Hiss At Their Kittens. Why cats hiss it’s a sound everyone has heard at some point. Now that you know how cats learned to hiss and why they do it now, you might also wonder about other ways that cats express anger, fear, and other unpleasantness.
Cats are a different species of mammal. Kittens are altricial, which means they are extremely immature and helpless for the first few weeks of life, unlike a horse who is precocial, which means they are born in an advanced state and can walk soon after birth.altrical species are completely reliant on their mother and unable to protect themselves from danger. 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.
Cats also hiss at their kittens to warn them of an incoming threat.
Like most mammals, mother cats are extremely protective of their babies. A warning hiss is a call to action. Unfamiliar objects in the house that move strangely may trigger your cat to hiss or be fearful. Feral cats will usually hide their kittens to keep them from other cats and predators of all kinds.
