Answers and explanations
Why does a cat hiss?
Answer: It is scared, stressed or sore, and wants space so it does not have to fight.
A hiss is a warning. The cat is trying to make a threat go away without a fight.
A cat hisses at you from behind the couch. What is the best thing to do?
Answer: Stay calm, look away, and back off slowly, leaving the cat a way out.
A hiss is a request for space. Giving it keeps you safe and helps the cat settle.
A cat is called spicy because it hisses. What is usually going on?
Answer: It is scared, stressed or sore.
Cats that get called spicy or grumpy are almost always frightened or uncomfortable. Find the cause and the cat usually settles.
Why is it a mistake to punish a cat for hissing?
Answer: It teaches the cat to stop warning and go straight to biting or scratching.
A cat that learns warnings are punished may stop giving them.
A usually friendly cat suddenly hisses when you touch its back. What could this mean?
Answer: It may be in pain, so mention it to the vet.
A sudden change in how a cat reacts to touch can mean it is hurting.
A cat hisses at a visitor it has never met. What does this most likely mean?
Answer: It is nervous of someone unfamiliar and wants space.
New people, smells and noises are common triggers. A quiet room and some time usually help.
Which signs often come with a hiss?
Answer: Flat ears, wide pupils, a puffed tail or an arched back.
Flat ears, wide pupils and a puffed or arched body show a frightened cat. A raised tail and slow blink show a friendly one.
A hissing cat is cornered in a small room. What should you do?
Answer: Open a way out, stay still and move back slowly.
A cat that cannot escape may lash out. Leaving it a way out lowers the chance of a bite or scratch.
Which of these is a myth?
Answer: A cat that hisses is just being bad.
Hissing is normal cat communication, not bad behaviour. It is a message worth listening to.

Is a hissing cat aggressive?
Usually not. Most hissing cats are scared, stressed or sore, and a hiss is their way of asking for space before things get worse. Calling a cat spicy, grumpy or bad misses the message. The cat is saying back off, I do not feel safe.
- A hiss helps cats avoid fights. It is normal cat communication.
- Growls, spits and swats are stronger versions of the same message.
- A cat that feels safe, has somewhere to hide and is not rushed is usually far calmer.
What should I do when a cat hisses at me?
Stay calm, look away, and turn side-on. Then move back slowly and leave the cat a way out. Do not reach for the cat, pick it up, chase it, shout or punish it. Give it time to settle with food and water nearby, and try again later, more slowly.
- Staring can feel like a challenge to a nervous cat.
- Punishing a hiss can teach a cat to skip the warning and go straight to biting.
- A cornered cat has nowhere to go, so make sure it has an exit.
Why does my cat hiss at a new cat or kitten?
Cats are territorial and need time to get used to a newcomer, so hissing is common. It usually means the cats need more space and a slower introduction. Keep them apart at first, with their own food, water and litter, and let them get used to each other’s scent before they meet.
- Slow introductions over days or weeks tend to go better than rushed ones.
- If hissing continues, or the cats start to fight, ask your vet or a cat behaviour professional for help.
Can hissing mean a cat is in pain?
Yes. A usually friendly cat that starts hissing, or hisses when touched in one spot, may be hurting. Pain is a common reason for a change in behaviour. If it is new or out of character, mention it to your vet.
- Other signs can include hiding, not eating, squinting or a hunched body.
- Do not try to examine a cat that is hissing. Let the vet do it.
