Why Do Cats Hiss?

It is a common misconception that cats hiss to be aggressive or confrontational when the exact opposite is often true. When it comes to cat behavior, the cat that hisses is often antagonized by another cat.

Cats often hiss when they are feeling threatened by someone or if something has changed in their environment. They may also hiss if they are being picked up or mishandled and in pain. Hissing is your cat’s way of letting you know that they are in discomfort.

A female cat with kittens may hiss, bite, or growl at someone who comes too close to her kittens. If you choose to realize why your cat is having a “hissy fit,” peruse this article.

5 Reasons Why Cats Hiss

A cat hiss is a low-intensity but distinct sound that cats make in certain situations. Cats will do this with their mouth open and sometimes show their teeth. It often sounds like a snake is creating the noise. When cats hiss, they may also change their body posture. The ears become flat, their back arches, and they look startled. There are some ordinary explanations for why your cat may be hissing.

1) They Feel Endangered

Cats often hiss at humans or other animals when they are feeling threatened. It could be that they are not cool with how they are being handled and are trying to let you or another human know this. Cats can be intimidating to another cat if they believe the other cat is infringing on their territory. Kittens tend to do this a lot.

Hissing is a distance-increasing behavior. Some of the reasons cats hiss at other cats are:

  • To caution the other cat to back off
  • To point out that they are stressed
  • Because of changes in the cat’s social group
  • Because they are irritated and do not intend to play

Cats sometimes hiss in certain situations where they feel threatened, like being put in a carrier to get ready to go to the vet. Cats sometimes hiss when they are in situations they do not want to be in, and they are not fearful of letting you know it!

2) They Are Afraid of the Unfamiliar

Some cats hiss because they fear new or unfamiliar situations, especially when something abruptly changes in their home. This could mean anything from the introduction of a new pet or loss of a pet in the home, to a new furniture arrangement in the house. A new pet can make them throw a hissing fit, as strange animals in the home can trigger them.

If there are any recent modifications in your home, you should try slowly acclimating your cat to the new circumstances that are occurring. You should do it gradually instead of all at once. Provide your feline companion with positive reinforcements that make them feel secure.

Give them treats and affection when needed to let them know they are safe. Introduce the change without making your cat feel threatened or vulnerable. This process allows them to begin to feel familiar with it in a way that becomes normal to them. With time, the hissing should decrease.

3) They Are Stressed

Cats and stress do not mix well. If your cat is hissing, it may be due to something stressing them out. Felines do not like to be alarmed, and they do not like loud disturbances. When it comes to your cat being stressed, there are a plethora of scenarios that are possible:

  • People setting off fireworks
  • Thunder and lightning
  • People yelling or fighting
  • Loud noises like a lawnmower

If cats are stressed due to any of the above noises, they may react defensively by hissing. When cats are stressed out from noises or loud sounds, they can become quite frightened. You can help them by reassuring them with a gentle voice and some affection if your cat permits them.

4) They Are in Pain

Cats who are in pain will sometimes display uncharacteristic aggression. They may hiss or growl if you touch them in a sensitive or delicate area. Sometimes when a feline is in pain, they may have a long, deep meow. Hunched posture or unusual hiding is another common indication that a cat may be in pain.

Cats may also hiss at each other when they are in pain. If your cat hisses when you try to pick them up, or if they are hissing at other cats in the home, you should take them to the vet, as they may be suffering from an injury or experiencing general pain.

5) You Are Coming Too Close to Her Kittens

Cats, like humans, are very protective of their babies. Momma cat may not like it when someone gets too close to her babies. She may perceive you or another human or animal as being a threat to her little ones, which can prompt her to hiss or demonstrate hostility toward them. Her hormones may cause her to develop a protective instinct toward her kittens.
