Osteoarthritis in Cats: Symptoms, Causes, and Treatment

At Las Vegas Cat Hospital, your cat’s comfort and quality of life are always our top priorities. We are excited to share that we are currently enrolling patients in a clinical study evaluating a new medication designed to help manage osteoarthritis (OA) in cats.

Osteoarthritis is more common in cats than many people realize, and because cats naturally hide discomfort, the signs can be subtle.

You may notice changes such as:

• Less interest in play

• Hiding more often

• Reduced grooming, especially around the hindquarters

• Ignoring the scratching post• Not stretching fully

• “Bunny hopping” when using stairs

• Hesitation to jump or reach favorite resting spots

To help identify cats who may benefit, we are offering FREE osteoarthritis screenings for eligible patients.

Cats who qualify for the clinical study may receive up to nine months of study-related care at no cost, which includes exams, lab work, and either the study medication or a placebo. Throughout the study, you will observe your cat at home and bring them in for complimentary monthly visits so our veterinary team can monitor their progress closely.

As a thank-you, participants who complete the study may receive up to an $800 veterinary hospital credit, which can be applied toward any future services, including ongoing osteoarthritis care.

If you think your cat may be showing signs of osteoarthritis, or if you would like to learn more, please contact our hospital to schedule your FREE OA screening and mention the CARE Cat OA Study when speaking with our receptionist.

Osteoarthritis in Cats: What Pet Owners Should Know

Osteoarthritis in cats, also called degenerative joint disease (DJD), is a common but often overlooked condition that causes joint pain, inflammation, and reduced mobility. As cats age, the cartilage that cushions their joints gradually wears down, leading to discomfort and stiffness.

Because cats are naturally good at hiding pain, many owners may not realize their pet is suffering from arthritis until the condition becomes more advanced. Recognizing the early symptoms of osteoarthritis in cats can help you seek veterinary care sooner and improve your cat’s quality of life.

What Is Osteoarthritis in Cats?

Osteoarthritis is a chronic, progressive joint disease that occurs when cartilage within a joint deteriorates over time. Cartilage normally acts as a protective cushion between bones. When it breaks down, bones rub against each other, causing pain, inflammation, and reduced joint function.

This condition most commonly affects older cats, but it can also occur in younger cats due to injury, obesity, or genetic factors.

Studies suggest that over 60–90% of cats older than 10 years show evidence of arthritis, although many cases remain undiagnosed because the signs can be subtle.

Ensure your cat's joy isn't hindered by osteoarthritis. Schedule a free OA screening today to keep them enjoying life's simple pleasures.

Signs and Symptoms of Osteoarthritis in Cats

The symptoms of cat arthritis are often behavioral rather than obvious physical signs. Common symptoms include:

• Difficulty jumping onto furniture or counters

• Reluctance to climb stairs

• Stiffness after resting or sleeping

• Reduced activity or playfulness

• Increased sleeping

• Decreased grooming, especially along the back and hips

• Irritability when touched near joints

• Difficulty getting into the litter box

• Weight gain due to decreased activity

If you notice these changes in your cat, they may be experiencing joint pain caused by osteoarthritis.

Causes of Osteoarthritis in Cats

Several factors can contribute to the development of arthritis in cats:

Aging

As cats grow older, normal wear and tear on joints increases the likelihood of cartilage degeneration.

Obesity

Excess body weight places additional pressure on joints, accelerating the breakdown of cartilage and worsening arthritis symptoms.

Previous Injuries

Joint trauma, fractures, or ligament injuries can lead to long-term joint damage and arthritis.

Genetic and Congenital Conditions

Some cats are born with joint abnormalities such as hip dysplasia or elbow dysplasia, which may lead to osteoarthritis later in life.

How Veterinarians Diagnose Arthritis in Cats

Diagnosing osteoarthritis in cats usually involves a veterinary exam and imaging tests.

A veterinarian may:

• Evaluate your cat’s mobility and gait

• Examine joints for pain, swelling, or stiffness

• Ask about behavioral changes at home

• Recommend X-rays (radiographs) to identify joint changes

Early diagnosis allows veterinarians to begin treatment sooner and prevent worsening joint damage.

Treatment Options for Osteoarthritis in Cats

Although osteoarthritis cannot be cured, several treatment options can help manage pain and improve mobility.

Pain Relief Medications

Veterinarians may prescribe medications designed specifically for cats to reduce inflammation and discomfort.

These may include:

• Non-steroidal anti-inflammatory drugs (NSAIDs)

• Injectable arthritis medications

• Other veterinarian-prescribed pain management options

Joint Supplements

Some cats benefit from supplements that support joint health, including:

• Glucosamine and chondroitin

• Omega-3 fatty acids

• Green-lipped mussel extracts

These supplements may help reduce inflammation and support cartilage health.

Weight Management

Maintaining a healthy weight is one of the most effective ways to reduce stress on joints and slow arthritis progression.

Environmental Changes at Home

Making simple adjustments can greatly improve comfort for cats with arthritis:

• Provide ramps or pet stairs to reach favorite sleeping spots

• Use low-entry litter boxes

• Offer soft, supportive bedding

• Keep food, water, and litter boxes easily accessible

Gentle Exercise

Light activity and play can help maintain muscle strength and prevent joint stiffness.

How to Prevent Arthritis in Cats

While arthritis cannot always be prevented, certain steps can help reduce the risk:

• Maintain a healthy body weight

• Provide regular veterinary checkups

• Feed a balanced, high-quality diet

• Encourage safe physical activity

• Address injuries promptly

Preventative care can help keep your cat’s joints healthy as they age.

When to See a Veterinarian

If your cat shows signs such as reduced jumping, stiffness, or decreased grooming, it is important to schedule a veterinary exam. Early diagnosis and treatment can significantly improve your cat’s comfort and mobility.

Frequently Asked Questions About Osteoarthritis in Cats

How common is arthritis in cats?

Arthritis is very common in older cats. Studies show that the majority of cats over age 10 have some degree of osteoarthritis.

Can young cats get osteoarthritis?

Yes. While arthritis is more common in older cats, younger cats can develop it due to injury, obesity, or congenital joint conditions.

Can osteoarthritis in cats be cured?

Osteoarthritis cannot be cured, but treatment can effectively manage pain and improve mobility.

How can I help my cat with arthritis at home?

Providing ramps, soft bedding, low litter boxes, and maintaining a healthy weight can greatly improve comfort for cats with arthritis.

Final Thoughts

Osteoarthritis in cats is a common condition that can significantly impact mobility and quality of life. Because cats often hide their pain, recognizing subtle behavioral changes is essential for early diagnosis.

With proper veterinary care, pain management, and supportive home adjustments, cats with arthritis can continue to live comfortable and happy lives.
