Arthritis, clinically known as degenerative joint disease or osteoarthritis, is a prevalent and painful condition affecting cats, particularly as they age. Much like in humans, this chronic issue involves the joints and is highly common in senior felines. Studies suggest that a significant majority, between 70% and 90%, of cats over the age of 12 years experience arthritis. Understanding Arthritis In Cats Treatment options is crucial for cat owners to ensure their beloved pets maintain a good quality of life.
Arthritis develops gradually over years, characterized by progressive changes within the joints. The cartilage, which normally acts as a protective cushion between bones in a joint, deteriorates. This breakdown allows bones to rub directly against each other, causing abnormal friction. The body may react by forming bony spurs or projections into the joint space. These changes lead to inflammation, swelling, and ultimately, pain in the affected joints.
While arthritis can affect any joint, it most commonly impacts the spine, hips, knees, and elbows in cats. It is a progressive disease, meaning it worsens over time if left unmanaged. The pain associated with these joint changes results in decreased mobility and can manifest as lameness in cats. Although age is a primary factor, arthritis isn’t exclusive to any specific breed or sex of cat.
Recognizing the Subtle Signs: Symptoms of Arthritis in Cats
One of the challenges in identifying arthritis in cats is their natural tendency to mask pain. While some cats may exhibit obvious signs like limping, swollen joints, or muscle atrophy, many others display more subtle changes that owners might overlook. Recognizing these less obvious symptoms is key to seeking timely arthritis in cats treatment.
Instead of clear lameness, cats with arthritis might show:
- Hesitancy to jump: They may be reluctant to jump onto favorite high places or struggle when attempting to jump down.
- Reduced activity levels: A decrease in playfulness, energy, and overall agility. They might appear less interested in activities they previously enjoyed.
- Grooming changes: Pain can make grooming uncomfortable, leading to a less kempt or even matted coat.
- Postural changes: They might adopt unusual sleeping or sitting positions to minimize joint stress and pain.
- Litter box issues: Pain when entering or using the litter box can lead to avoidance, causing them to eliminate outside the box. It’s important to rule out medical urinary issues first, but consider arthritis if behavioral or urinary causes are not found.
It’s crucial to note that these symptoms typically develop gradually, not overnight. Observing these subtle shifts in behavior and physical ability is essential for early detection and effective arthritis in cats treatment.

Unraveling the Causes: What Leads to Arthritis in Cats?
Arthritis in cats can arise from various factors. In many cases, it develops without a clear underlying cause, often linked to the natural aging process. Genetics may also play a role in this age-related form of arthritis. However, arthritis can also be triggered by joint injuries, even seemingly minor ones.
Potential causes of arthritis in cats include:
- Ligament injuries: Tears or sprains, such as an ACL tear, can destabilize joints and accelerate cartilage wear.
- Immune-mediated diseases: Conditions like immune-mediated non-erosive polyarthritis involve the body’s immune system attacking joint tissues.
- Tick-borne diseases: Lyme disease and other tick-borne illnesses can cause joint inflammation and contribute to arthritis.
- Direct trauma: Accidents, falls, or other forms of physical injury can directly damage joints, leading to arthritis.
- Infections: Joint infections can damage cartilage and bone, increasing arthritis risk.
- Congenital defects: Abnormal joint development present from birth can predispose cats to early-onset arthritis.
The progression of arthritis is partly due to the joint’s inherent response to injury. When a joint is damaged, the cartilage releases enzymes that further degrade cartilage and collagen, exacerbating inflammation and perpetuating the cycle of joint damage. Understanding these causes helps veterinarians tailor arthritis in cats treatment plans effectively.
Diagnosis: How Veterinarians Identify Arthritis in Cats
Veterinarians often suspect arthritis based on a thorough physical examination. However, confirming the diagnosis usually requires further diagnostic tests. Interestingly, some cats are stoic and may not show obvious symptoms, leading to incidental diagnoses during routine exams or X-rays for other reasons. Early diagnosis is paramount to initiating timely arthritis in cats treatment.
During a physical examination, a veterinarian may look for the following signs indicative of arthritis:
- Lameness: Obvious limping or favoring of a limb.
- Gait or posture changes: Alterations in walking style or stance, including a hunched posture.
- Difficulty sitting or rising: Struggling to get up from a lying position or sit down comfortably.
- Swollen or thickened joints: Visibly enlarged or palpably thicker joints.
- Crepitus: A clicking, popping, or grating sound or sensation in the joints during movement.
- Pain on joint palpation: Discomfort or pain response when the veterinarian touches or manipulates the joints.
- Reduced range of motion: Limited flexibility and movement in affected joints.
While a physical exam can strongly suggest arthritis, X-rays (radiographs) are the gold standard for confirming the diagnosis. X-rays allow veterinarians to visualize the bones and joints and identify characteristic arthritic changes, such as:
- Joint distention: Swelling and fluid buildup within the joint capsule.
- Bony outgrowths (osteophytes): Abnormal bone spurs forming around the joint.
- Soft tissue thickening: Inflammation and swelling of tissues surrounding the joint.
- Narrowed joint spaces: Reduced space between bones within the joint, indicating cartilage loss.
- Joint mice: Calcified, free-floating bony fragments within the joint.
In some cases, veterinarians might also recommend a trial period with pain medication to assess the cat’s pain level and response to arthritis in cats treatment.

Comprehensive Strategies: Treatment of Arthritis in Cats
Arthritis is a highly prevalent condition in cats, but thankfully, numerous options are available to help manage pain, improve mobility, and enhance their quality of life. A multimodal approach, combining several therapies, is generally the most effective strategy for arthritis in cats treatment.
Weight Management:
Obesity significantly exacerbates arthritis. Excess weight puts additional stress on already compromised joints. For overweight cats, weight reduction is often the first and most impactful step in arthritis in cats treatment. Veterinarians can recommend specific weight loss diets and guide caloric intake adjustments.
Medications for Pain Relief and Inflammation:
- Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Medications like meloxicam (e.g., Metacam) and robenacoxib (Onsior) are effective in reducing pain and inflammation associated with arthritis. However, NSAID use requires careful monitoring due to potential side effects on organ function, and long-term use may have limitations.
- Gabapentin: This medication, used for various purposes, has pain-relieving properties that can benefit arthritic cats.
- Opioids: While effective for pain control, opioids require careful administration and may cause sedation.
- Polysulfated Glycosaminoglycan (PSGAG) (Adequan): This injectable medication supports joint health by inhibiting cartilage-damaging enzymes. Although not officially labeled for cats, veterinarians may use it off-label.
- Amantadine: May provide additional pain relief in some cats when used in conjunction with other medications.
- Frunevetmab (Solensia): A newer injectable medication specifically developed for feline arthritis. It utilizes monoclonal antibodies to target a key pain mediator. While newer, studies suggest it can be a beneficial option for arthritis in cats treatment.
Supplements to Support Joint Health:
- Glucosamine and Chondroitin: Over-the-counter supplements that support cartilage health. Veterinarian-recommended brands like Dasuquin and Cosequin are preferred due to their established safety and efficacy.
- Omega-3 Fatty Acids: These supplements can help reduce inflammation within the joints.
- CBD (Cannabidiol): While gaining attention for pain relief, research on CBD in pets is still limited, and legal and quality concerns exist. Consult with your veterinarian before using CBD products as part of arthritis in cats treatment.
Medical and Supportive Therapies:
- Laser Therapy (Cold Laser): Reduces inflammation and pain using light energy. Treatment protocols often involve initial frequent sessions, gradually tapering down.
- Acupuncture: May offer pain relief for some cats, although acceptance varies among individuals.
- Stem Cell Therapy: Shows promise in other species, but more research is needed in cats to confirm its effectiveness for arthritis.
- Warm and Cold Compresses: Provide temporary pain relief by increasing blood flow (warm) or reducing inflammation (cold).
- Physical Therapy: Helps with weight loss, improves joint mobility, and strengthens supporting muscles.
- Surgery: While not a first-line arthritis in cats treatment, surgical options like joint fusion, joint replacement, or amputation may be considered in specific cases to alleviate pain and improve quality of life. However, surgery doesn’t guarantee arthritis will not recur over time.
Long-Term Care: Recovery and Management of Arthritis in Cats
Arthritis is a chronic, irreversible condition. Therefore, “recovery” in the traditional sense isn’t possible. However, effective arthritis in cats treatment and ongoing management can significantly slow disease progression and provide cats with a comfortable and active life. Many cats with arthritis display subtle signs, highlighting the importance of diligent monitoring by owners.
While diagnosis often occurs in cats over 10 years old, arthritis can start much earlier. Recent studies suggest that signs of arthritis may be present in around 60% of cats as young as 6 years old.
As cats age, owners should be vigilant for subtle changes like decreased jumping ability, reduced playfulness, grooming difficulties, or litter box avoidance. Without appropriate arthritis in cats treatment, arthritis can progress to become debilitating and severely painful. Regular veterinary check-ups and proactive discussions about arthritis management are crucial for all senior cats.
Prevention: Reducing the Risk of Arthritis in Cats
While not always preventable, proactive measures can help reduce the risk or severity of arthritis in cats:
- Maintain a healthy weight: Preventing obesity is paramount. If your cat is overweight, work with your veterinarian to implement a safe and effective weight loss plan.
- Early joint support: Discuss cartilage-protectant medications or supplements with your veterinarian, especially for cats at higher risk (e.g., certain breeds, history of joint injury). Early intervention may help protect cartilage before significant damage occurs.
