A cat walking with an arched back can reveal how it is feeling at that time physically and mentally. A cat’s body language and posture, such as arching the spine, has a number of different explanations.
- Stretching the muscles after yawning
- Hunting and preparing to pounce
- Making itself look bigger
- Pain in the abdomen or spine
You need to identify why your cat is walking with an arched back. If your cat is scared, you should calm it down. If it is in pain, you need to find out why. Cats hide their pain until physically incapable of doing so anymore.

Why Do Cats Arch Their Spines?
Subtle differences can explain why a cat has an arched back. We’ll now take a look at the most common explanations and what they mean.
Cat Stretching Its Back Muscles
After a long sleep, a cat needs to stretch. A cat needs its muscles to be supple for future hunting. By arching its back and stretching, the cat unlinks any tight muscles in its back.
Some cats arch their back when being petted. The behavior will invariably be accompanied by purring.
The cat is also sharing its scent with you. Felines have scent glands in the anus and are releasing their scents on you. Your cat is marking you as a source of pleasure and inviting you to exchange scents.
Is My Cat Hunting?
A cat may arch its back when hunting. This position is a precursor to pouncing. The cat is arching to provide additional spring to its movements.
You may notice your cat arching its back during play. This is especially likely among kittens. For kittens, play is a practice run for life as an adult cat. Kitten games teach hunting techniques.
Even an adult cat will play to sate its hunting instincts. If the cat cannot go outside, it’ll hunt toys. This can lead to the arched back, and pounce.
Sometimes, a cat will arch its back when excited and overstimulated. Again, this is common in kittens. Your cat may have more energy than it knows what to do with.
Cat Arching Its Back in Pain
Coupled with an arched back, these actions suggest a cat is in pain:
- Agitation and reluctance to settle
- Uncharacteristic aggression
- Refuses to be handled
- Depression and lethargy
- Excessive grooming or licking
Cats mask any sign of discomfort. Felines worry that demonstrating pain is showing weakness. This opens the cat up to attacks from predators.
A cat arching its back in pain is clearly in distress. According to the Journal of Feline Medicine and Surgery, pain in cats is difficult to manage. Cats are allergic to many painkilling drugs and anesthetics.
Speak to a vet ASAP and monitor your cat’s other behaviors. The problem may be a short-term external injury or a significant medical concern.
Cat Limping and Arching Its Back
A cat that limps is clearly in pain. Before seeing a vet, assess what is causing the problem. Reasons for cats to limp include:
- Foreign objects embedded in the paw
- Muscles strains or pulls
Check your cat’s paws for any signs of embedded glass or wood. If you find no foreign objects, the problem is musculoskeletal.
It is easy for cats to pull muscles. Your cat may have fallen from height. It may have misjudged a jump between 2 surfaces. It may have pounced too quickly while hunting. Moving too quickly can pull or tear muscle tissue.
These muscle pulls could be the legs, back, or abdomen. The limp and arched back is an attempt at reducing the impact on the pained area. This injury is treated with restricted movement and pain medication.
Arthritis will reveal itself gradually. According to the Journal of Neurophysiology, the symptoms worsen over time. Your cat is reluctant to place weight on painful joints. This explains the limp and arched back.
Old Cat Walking with Hunched Back
It is believed that 80% of cats aged ten or over have arthritis. The condition isn’t breed or size-specific. Any cat can develop arthritis later in life. Common symptoms of this condition are:
- Reluctance to use the litter box
- Inability to run or jump
- Refusing any form of handling
- Limping gait
- Swelling around the joints
Feline arthritis cannot be cured, but the pain can be managed. Options could include supplements, pain medication, and massage. Other concerns that affect older cats include:
- Kidney failure
- Heart problems
- Digestive issues
- Displacement of the hip
These concerns may also affect the stomach. This is why a cat arches its back. It is keeping its stomach as far from the ground as possible.
Does My Cat Feel Threatened?
A cat arching its back is a classic pose of fear. The cat is trying to make itself look big and intimidating. This is sometimes called the ‘Halloween Cat’ pose. Signs that your cat is arching its back in fear include:
Your cat may not realize it is doing this. It is an involuntary reaction, known as piloerection. When something frightens a cat, its body releases adrenaline. This, in turn, causes piloerection.
If your cat is adopting this pose, you should back away. Do not give your cat anything else to fear. Look around and try to understand the response. If there is another animal nearby, protect your cat from a safe distance. If you cannot see a threat, then just walk away.
No cat should live in a constant state of anxiety. As Veterinary Clinics of North America explains, this leads to health and behavioral problems.
Temporary Reasons Cats Feel Threatened
Many things can spark a short-term fear response in cats. Although felines appear calm and indifferent, they are nervous. Common triggers include:
- New, unfamiliar scents
- Unfamiliar humans or animals in the cat’s territory
- Unique and novel experiences. Cats like routine
- Triggering of a negative memory
- Loud noises
A reaction to these stimuli should be fleeting. Your cat will soon return to behaving as normal. Give your cat space. Once it falls back in its usual routine, it will forget about the stressful experience.
Permanent Reasons Cats Feel Threatened
A medical condition may be to blame for its nerves. If not, make your cat’s life as comfortable as possible.
If your cat has suddenly developed an anxiety disorder, think about why. A sudden change is often the catalyst:
- Has somebody new moved into the home, such as a lodger or baby?
- Have you got a new pet?
- Do you have new neighbors? They may be noisy or have a pet that bullies your own cat.
- Have you re-arranged or changed the furniture in your home?
- Have you started working longer hours, spending more time away from the home?
If you work out why your cat is anxious, then you should attempt exposure therapy. Slowly introduce your cat to that what it is afraid of. Over time, your cat’s confidence will start to build.
Cat Arching Its Back and Shaking Its Tail
This behavior denotes marking. Your cat is using its anal scent glands to claim territory. Cats often perform this action against walls and doors. It looks like the cat is urinating, but nothing is released.
Your cat is releasing a scent. Other cats will pick up on it and will know that a property has been claimed.
Most spayed or neutered cats will cease this behavior. Fixed cats are less territorial. If your cat is still marking, it may feel insecure in your home. Spend more time with your cat and ensure another pet is not bullying it.
