Lameness in cats: How to tell if it's an orthopedic problem?
Updated: 11 hours ago
Everything you need to know about the assessment and origin of lameness in cats
A limping cat doesn't always have an orthopedic problem. Limping can be caused by a paw injury, an ingrown claw, an abscess following a bite, trauma, joint disease, or, more rarely, a neurological or circulatory disorder.
In cats, joint problems are often subtle. Rather than clearly limping, they may jump less high, hesitate before jumping onto furniture, use their litter box less often, or groom themselves less thoroughly. Osteoarthritis is very common in older cats, but it often goes unnoticed.
It is primarily treated with medication, weight management, and home modifications. Surgery is considered in certain specific situations. Sudden paralysis of the hind legs, cold paws, or cries of pain require emergency veterinary attention.
A dog with a sore paw usually shows it quite clearly. It limps, sometimes whimpers, and looks at its paw dramatically. A cat, on the other hand, prefers discretion.
In nature, showing weakness can be risky. Many cats therefore tend to hide their discomfort, reduce their activity quietly, and adapt to their pain rather than showing it.
The result: when a cat is clearly limping, the problem has sometimes been present for some time. And even when it isn't limping at all, it may still be suffering from a joint problem.
Not all lameness is orthopedic.
Before considering bones and joints, several other common causes must be ruled out. Lameness in cats can be caused by:
an abscess following a bite or scratch, especially in cats that go outside;
a wound, a splinter or a foreign object in a pad;
an ingrown claw, particularly in older cats;
a sprain or a bruise after a fall;
a fracture or dislocation resulting from trauma;
a joint disease, such as osteoarthritis;
a neurological disorder;
more rarely, a bone tumor;
A circulatory problem, such as thromboembolism.
Some of these causes resolve quickly. Others require further examination, or even emergency care.
Abscess: the surprising cause of adventurous cats
In outdoor cats, an abscess is one of the most common causes of sudden lameness. A cat bite often leaves a small, almost invisible wound. However, bacteria can get under the skin and form a pocket of pus within a few days.
The cat may then limp, refuse to put weight on the affected leg, become lethargic, eat less, or develop a fever. A hot, painful swelling sometimes appears on the leg.
An abscess requires veterinary evaluation. It can often be drained, and treatment for pain and infection may be prescribed. It's not orthopedic. But it's common, and worth mentioning before discussing X-rays.
Signs of an orthopedic problem in cats
An orthopedic problem affects the bones, joints, ligaments, or tendons. In cats, it often manifests as behavioral changes rather than obvious lameness. Your cat may, in particular:
jump less often or from a lower height;
hesitate before climbing onto a piece of furniture, or climb onto it in several stages;
descend surfaces carefully rather than jumping;
use the stairs less;
relieving itself next to the litter box, especially if it has high sides;
grooming less well, particularly the lower back and hind legs;
to have claws that are too long, because it wears them down less;
sleep more or play less;
to become irritable when flattered or hugged;
A cat may have a stiffer gait, especially after resting.
Many owners attribute these changes to age. "He's getting older, he's calmer." However, age is not an illness. A cat that no longer jumps on the counter hasn't necessarily become well-behaved: it may be in pain.
Osteoarthritis is a degenerative joint disease. The cartilage gradually wears away, the joint becomes inflamed, and bone changes appear over time.
In cats, it has long been underestimated. However, several studies have shown that signs of osteoarthritis are visible on X-rays in a large proportion of older cats. The joints most often affected are the hips, elbows, knees, hocks, and spine.
Unlike in dogs, feline arthritis is not always linked to an injury or a known developmental problem. It can appear without any obvious cause, especially with age. However, certain factors can contribute to its development or worsen its symptoms, such as excess weight, a previous injury, or certain breed predispositions.
Other orthopedic problems to be aware of
Osteoarthritis is not the only orthopedic cause of lameness in cats. Other conditions may require evaluation or surgery:
fractures, often resulting from a fall, car accident or trauma;
Cruciate ligament rupture, less frequent than in dogs, but possible, especially in overweight cats;
patellar luxation, which affects some races more than others;
hip dysplasia, reported particularly in certain large breeds, such as the Maine Coon;
Spontaneous fracture of the femoral head, which mainly affects young, neutered, and overweight male cats;
certain hereditary cartilage abnormalities, such as in the Scottish fold;
Bone tumors, though rarer, should be considered in cats with persistent and progressive lameness.
Each of these conditions requires precise diagnosis, as treatment varies considerably.
Diagnosis, treatments and solutions for feline joint problems
Examining a limping cat can sometimes be a bit of a challenge. At the clinic, many cats freeze, hide, or refuse to walk.
Some appear perfectly normal on the examination table, before starting to limp again as soon as they return home. That's why your observation is so valuable.
Your veterinarian will be able to, among other things:
collect the history and changes in behavior that you have noticed;
observe your cat's gait when it agrees to move;
palpate the limbs, joints and spine;
assess pain and range of motion;
to perform X-rays, often under sedation;
Blood tests are recommended, particularly before prescribing certain medications.
In some cases, further examinations may be necessary, such as joint fluid analysis or advanced imaging.
Filming your cat: a surprisingly useful tool
Before the appointment, take a few videos of your cat at home. Film him while he's walking, climbing up or down furniture, using the stairs, or going into his litter box. A few seconds is often enough.
These images allow your veterinarian to observe behaviors they might never see in a clinic setting. Your cat probably won't be thrilled to become a star. But for once, their acting skills might actually come in handy.
How is osteoarthritis treated in cats?
Osteoarthritis cannot be cured. However, it can be well managed, which significantly improves the cat's quality of life.
Treatment typically combines several approaches:
weight management, which reduces the load on the joints;
pain medication, prescribed according to the cat's health condition, particularly its kidney function;
newer treatments, such as certain monthly antibody injections targeting pain related to osteoarthritis;
rehabilitation and gentle exercise, adapted for cats;
certain supplements, according to your veterinarian's recommendations;
Adapting the environment often makes a big difference.
The cat doesn't complain. A good treatment plan often allows it to resume activities it had quietly abandoned.
Adapting the home: small changes, big impact
A few simple modifications can help a cat with arthritis stay active and independent:
a litter box with low sides, easy to access;
steps or ramps to access his favorite places;
bowls of food and water accessible without jumping;
a cozy, warm and easily accessible bed;
anti-slip mats on slippery floors;
Gentle games to encourage him to move without straining him.
The cat loves his high places. He simply prefers to climb up the stairs when his joints need it.
When is surgery considered?
The majority of cats with arthritis are treated without surgery.
However, surgery may be recommended in certain situations, for example:
a fracture that needs to be stabilized;
a dislocation of a joint;
a rupture of the cruciate ligament;
a dislocation of the kneecap that causes pain or repeated limping;
a spontaneous fracture of the femoral head;
A very painful hip despite medical treatment.
For hip problems, femoral head and neck excision is a common surgical procedure in cats. This removes the head of the femur to eliminate the painful contact between the bones. A fibrous joint then forms in its place.
Thanks to their small size and light build, cats generally recover very well from this procedure. In some cases of severe osteoarthritis affecting a specific joint, other interventions, such as joint fusion, may be considered.
The choice always depends on the cat's condition, age, overall health, and quality of life.
Cats are particularly sensitive to changes in their environment. Transport, new smells, noises, and the presence of other animals can increase their stress.
In mobile surgery, the specialized team travels to the veterinary clinic that already treats your cat. This avoids a trip to a new facility and ensures your cat remains surrounded by a team familiar with its medical history and reactions.
Several feline orthopedic procedures, such as stabilization of certain fractures or femoral head excision, can be performed on an outpatient basis when the partner facility has the necessary equipment. Some cases, such as a polytrauma or unstable cat, require continuous monitoring at a referral center.
How does Coupez help cats that limp?
At Coupez, each case begins with the analysis of information provided by your veterinarian: examination, x-rays, history and videos, when available.
We assess whether the limp is due to an orthopedic problem, whether surgery can be beneficial, and whether it can be performed in mobile mode.
When surgery isn't the most appropriate option, we discuss it with your veterinarian, who can then develop a suitable medical treatment plan. Your veterinarian knows your cat. Our team brings its surgical expertise. Together, we'll find the solution that will help your cat regain its former height.
In conclusion
A cat that jumps less is not necessarily a cat that is aging gracefully. Lameness in cats is not always dramatic.
It often hides behind neglected litter boxes, an unkempt sofa, or a less-than-perfect coat. An abscess, injury, joint disease, or emergency can all cause lameness. Only an evaluation can determine the cause.
When the problem is orthopedic, several solutions exist: medical treatment, environmental adjustments, and, in some cases, surgery. Your cat won't tell you it's in pain. But it often leaves you clues. You just need to know how to read them.
