Septic Arthritis in Cats: Causes, Symptoms, and Treatment How To Identify and Manage Septic Arthritis In Cats

Septic Arthritis in Cats: Causes, Symptoms, and Treatment

Septic Arthritis is a dangerous and painful joint infection that affects cats. We discuss this disease extensively in this article.

Septic Arthritis is a serious and painful joint infection that affects cats. Inflammation, swelling, and discomfort are brought on by bacteria getting into the joint. All breeds and ages of cats can be affected by this ailment, but older cats and cats with compromised immune systems are more likely to get it. Septic arthritis can cause irreversible joint damage and disability if left untreated.

The causes, signs, diagnosis, and available treatments for septic arthritis in cats will all be covered in this article.



Septic arthritis in cats is caused by bacterial infections that penetrate and enter the joint. This can occur due to a number of reasons, including:

  • Bacterial infections in other parts of the body spread to the joint.

  • Trauma or injury to the joint that allows bacteria to enter.

  • Dental infections that spread to the joint.

  • Weakened immune systems in older cats or those with chronic illnesses.

Additionally, certain risk factors can increase the likelihood of a cat developing septic arthritis, including obesity, joint problems such as osteoarthritis, and previous joint infections.

Can Cats Get Gout?

Yes, cats can develop gout arthritis, which is a type of joint inflammation caused by the buildup of uric acid crystals in the joints. The most common causes of gout in cats are metabolic issues or diets high in purines, which can result in uric acid levels in the blood that are too high. Cats with gout may experience edema, discomfort, and stiffness in the afflicted joints. Typically, purine restriction and medicine to control pain and inflammation are used as treatments for feline gout.

Arthritis In Cats Symptoms

Cat arthritis symptoms can vary, and some include:

  • Limping or lameness in one or more limbs.

  • Swelling and pain in the affected joint.

  • Difficulty with walking, running or jumping.

  • Stiffness or reluctance to lift the affected limb.

  • Warmth or redness in the affected joint.

  • Loss of appetite.

  • Increased urination and thirst

  • Fever.

Take your cat to the doctor as soon as you feel they may have septic arthritis so they may be properly diagnosed and treated. Early intervention is key in preventing long-term joint pain in cats and reducing the severity of symptoms.


Cats with septic arthritis are often diagnosed using a combination of physical examination, lab testing, and imaging procedures. Among the diagnostic methods adopted are:

  • Physical examination: The vet will examine the affected joint for signs of swelling, redness, and pain.

  • Blood tests: Blood tests can assist in detecting the kind of bacteria causing the illness and can also help identify infection symptoms, such as raised white blood cell counts.

  • Joint fluid analysis: The vet may aspirate fluid from the affected joint and have it analyzed for the presence of bacteria, white blood cells, and other signs of infection.

  • Radiology: X-rays or other imaging techniques may be used to visualize the affected joint and identify any changes in the bone structure.

The findings of these tests will allow the veterinarian to identify septic arthritis in your cat and decide the best course of treatment.

Treatment and Management

The treatment and management of septic arthritis in cats typically involves a combination of antibiotics and supportive care. Some of the specific steps involved in treating septic arthritis include:

  • Antibiotics: Antibiotics are prescribed to kill the bacteria causing the infection. The type and duration of antibiotics will depend on the specific type of bacteria involved.

  • Pain management: Pain relievers and anti-inflammatory medications may be prescribed to relieve pain and swelling in the affected joint.

  • Joint drainage: In some cases, the vet may need to drain fluid from the affected joint to relieve pressure and promote healing.

  • Strict confinement: It is important to limit your cat's activity during the healing process to prevent further injury and allow the joint to heal properly.

  • Weight management: Maintaining a healthy weight can help reduce the stress on the affected joint and prevent future joint problems.

In addition to these specific treatments, it is also important to follow your vet's recommendations for any additional care and monitoring, such as follow-up exams and lab tests.

Preventive Tips

There are several steps that pet owners can take to help prevent septic arthritis in cats, including:

  • Maintaining good oral health: Dental check-ups and regular teeth cleanings can help prevent oral infections from spreading to the joints.

  • Preventing joint injuries: Providing a safe and secure environment for your cat can help prevent joint injuries and reduce the risk of infection. 

  • Maintaining a healthy weight: A sudden onset of arthritis in cats can come as a result of obesity in your cat. Keeping your cat at a healthy weight can reduce the stress on their joints and prevent future problems.

  • Regular exercise: Regular exercise can help maintain joint health and mobility. In addition to that, you can get toys for your cat to aid in regular exercise.

  • Providing a balanced diet: A balanced diet that provides adequate nutrition and hydration can help support a healthy immune system.

  • Routine vet check-ups: Regular vet check-ups can help identify and treat joint problems early before they become serious infections.

By following these preventive tips, pet owners can help protect their feline companions from the painful and debilitating effects of septic arthritis. Nevertheless, seek veterinary care promptly if you suspect that your cat may be developing joint problems, as early intervention is key in preventing permanent joint damage and ensuring a full recovery.
