Why Do Cats Arch Their Backs?

Cats find themselves in many different situations throughout their day. They might face a rival kitty on the block or get a pet from their favorite human.

All these interactions call for different responses. Felines are incredibly emotive animals with a lot to say and ranging opinions of the world. Hence, understanding kitty body language can be tricky. So let’s dive into why cats might arch their backs and what this means.

1. Why Do Cats Arch Their Backs When Scared?

They might come face-to-face with a threat that makes them feel uncomfortable. This will result in them arching their back, hair standing on end, and often hissing. Most cat parents have seen their cats in this position at one time or another. 

This stance will make the cat appear bigger and hopefully scare away the threat. This position slightly differs from when a cat is suddenly startled, but more on that later. By arching their back, cats aim to ward off their opponent, hoping they might look for a smaller victim rather than our big, vicious, and very dangerous kitty.

This is a direct reaction to a dangerous situation. This kind of body language translates to “I feel threatened, but I am ready to defend myself if you come closer.”

The best move would be to leave the unfriendly cat alone and not try to approach them. If it’s your cat, it’s best to speak calmly, but not come in the way between rivals.

2. They Are Playing

 If your cat is in a playful mood, it might also get into a similar position. This is similar to their  “ready to attack” pose. However, you can differentiate between this and their response to threats. When threatened, cats growl or hiss and show their teeth.

This behavior can be directed to a play buddy, a favorite toy, or a human. You can expect pouncing and bouncing behavior when the cat is stimulated. This is an indication that the cat is comfortable and friendly.

3. Simply Stretching

A brief arch of the back can be written off as a lazy stretch – just like us humans. However, cats are more flexible than us. So, if your cat arches back with its eyes closed, it’s probably having a good stretch..

A common cat stretch would be a nose-down, tail-up, with outstretched paws. This simply indicates laziness or sleepiness and a way to stretch. You’ll most often spot your cat arching her back just after she’s uncoiled from her favorite sleeping position.

4. Why Do Cats Arch Their Backs When You Pet Them?

You’ve hit the spot! This is a good sign if your cat is exhibiting this behavior during a pet or scratch. This means that you’ve triggered a positive response in the cat and they appreciate your touch.

They are simply asking for more pets and they will often turn in circles. They’ll arch their backs to give you easier access to the sweet spot.

But with all that being said, where are the common sweet spots?

  • Behind the ears
  • Above the tail
  • Under the chin
  • Down the spine

Remember to be careful when petting your cat, especially the belly and tail area. These are the most sensitive spots on a cat and won’t always be met happily. 

There is a thin line between contentment and discomfort – especially with our feline friends. When a cat becomes overstimulated, it will most likely end up in a scratch or a bite.

5. They Might Be Displaying Their Bum

A common reason why your cat is arching his back maybe because he is presenting his bum – that’s right! Do not take this as a negative sign.

Cats display their bottoms to each other as a sign of friendly greeting, and they tend to do this to humans to ask for more pets. It’s an indication that they feel comfortable and happy around you.

6. Your Cat is in Heat

If you have a female, non-spayed cat, her arched back could mean she’s in heat (ready for mating). Cat’s cycles can vary according to their age, so keep your eye out for the signs. If you find your cat or kitten arching back when walking around the house, she might be in heat.

Other signs your cat is in heat include (source):

  • Being overly affectionate
  • Constant meowing
  • Moving her tail
  • Rolling.

Cat Reactions To Being Touched

As mentioned, it’s usually a good sign when a cat arches its back when you touch them. But, your characteristics and personality type can greatly affect how comfortable the cat feels around you. Don’t be offended if you don’t see your cat arching back in delight.

Cats may instantly feel comfortable with you or barely tolerate you in exchange for yummy food and security. This can depend on how you touch the cat and your behavior towards the cat.

Gaining a cat’s trust is rarely simple and often relates to previous experiences. It can be harder to gain the trust of cats who didn’t have good experiences with humans in the past, such as abandoned or shelter cats.

If cats had a bad experience with a human of a certain gender or appearance, they might stay clear of similar-looking people or display an aggressive stance.

1. How to Tell They Don’t Like It

If your cat continuously shows an aversion to being touched, it’s better to leave them in peace.

Signs that your cat isn’t enjoying themselves include:

  • Your cat biting you or scratching
  • Moving their tail aggressively
  • Moving away
  • Hissing or making sounds

No two cats are the same and might only display less obvious signs of aggression or irritability. The best bet is to leave the cat alone as soon as they show any of these behaviors.

Some cats enjoy physical touch more than others, and it’s safer to keep your affections light until you get to know them, and they get used to your presence.

This small act might even result in the cat trusting you a lot faster and improving your relationship in the longer term.

2. How To Tell If They Do Like It

Why do cats arch their back and rub against you? Because they like your attention. Like arching their backs, cats exhibit numerous behaviors that indicate that they appreciate being touched.

However, not all cats are the same. Here are some common positive responses to human attention:

  • Purring
  • Kneading their owners
  • Kneeling with their tail up
  • Ears pointed outward
  • Relaxed facial expressions
  • Relaxed body language
  • Slow wave of the tail
  • Slow blinking

They might give you a slight nudge to encourage you to continue if you dare stop. Or a passive-aggressive claw might meet you on a tender spot. Fingers crossed they pick the first option.
