Non-inflammatory muscle disease in cats is a disease that affects cats' activities and can be very frustrating. In this article, we look at how to identify the signs and how to treat this muscular condition.

Cats are active and energetic animals that rely heavily on their muscular system for daily activities such as jumping, climbing, and running. Cats, like people, can suffer from a variety of muscular illnesses that can have a substantial influence on their quality of life. Non-inflammatory muscle disease is one such disorder that can cause weakness, muscle mass loss, and other symptoms in cats. 

In this article, we will look at the complexities of non-inflammatory muscle illness in cats and the best approaches to treat it.

What Causes Muscle Atrophy in Cats?

Cats with non-inflammatory muscle illness may have a variety of underlying reasons, including genetic, metabolic, and external factors. Some of the known causes of muscle degeneration in cats are as follows:

  • Genetic Disorders: Certain genetic disorders can cause non-inflammatory muscle disease in cats. Examples include congenital myopathy, hypokalemic periodic paralysis, and glycogen storage disease.

  • Metabolic Disorders: Metabolic disorders, such as hyperthyroidism, diabetes, and renal disease, can lead to muscle weakness and atrophy in cats.

  • Toxins: Toxin exposure, such as lead, can induce muscular illness in cats.

  • Nutritional Deficiencies: Inadequate nutrition or a diet deficient in certain nutrients, such as vitamin E or selenium, can lead to muscle disease in cats.

  • Trauma: Trauma or injury to the muscles, such as from a fall or accident, can also cause non-inflammatory muscle disease in cats.

Muscle Wasting in Cats Symptoms

Non-inflammatory muscle illness in cats can present with a variety of symptoms, which vary depending on the true cause and severity of the condition. A few of the most frequently observed signs of non-inflammatory muscle sickness in cats are as follows:

  • Weakness: Cats with muscle disease may exhibit generalized weakness or have difficulty standing, walking, or jumping.

  • Muscle Atrophy: Muscle atrophy or wasting is a common symptom of muscle disease in cats. The muscles may appear smaller or less defined than usual.

  • Lethargy: Cats with muscle disease may seem more tired or lethargic than usual and may spend more time sleeping or resting.

  • Tremors or Shaking: Muscle disease can cause tremors or shaking in cats, especially in the limbs.

  • Swallowing Difficulties: Cats with muscular illnesses may have trouble swallowing or regurgitating their food.

  • Respiratory trouble: In extreme situations, muscular disease can damage the breathing muscles, causing respiratory trouble.

  • Change in Posture: Cats may adopt a hunched or crouched posture or have an arched back due to muscle weakness.


Non-inflammatory muscle disease in cats can be difficult to diagnose because the symptoms are nonspecific and might resemble other underlying health concerns. A veterinarian, on the other hand, can run a number of diagnostic tests to identify if a cat has a non-inflammatory muscle illness. A veterinarian may perform the following diagnostic tests:

  • Physical Examination: A complete physical examination will be performed by the veterinarian to examine the cat's muscle tone, strength, and coordination.

  • Blood testing: Blood tests can assist in detecting metabolic and hormonal abnormalities, such as low thyroid hormone levels, which can lead to muscle illness.

  • Muscle Biopsy: A muscle biopsy is the examination of a small piece of muscle tissue under a microscope. This test can aid in the identification of any abnormal changes in muscle tissue, such as inflammation or degeneration.

  • Imaging Tests: Imaging studies, such as X-rays, CT scans, or MRI scans, can aid in the examination of muscle tissue and the identification of any abnormalities or injuries.

  • Electromyography (EMG): EMG is a diagnostic procedure that includes introducing tiny needles into muscle tissue to detect electrical activity. This test can help discover muscle weakness or abnormalities.

  • Genetic Testing: If a genetic disorder is suspected, genetic testing can help identify any specific gene mutations that may be responsible for the muscle disease.

Cat Muscle Wasting Treatment 

Non-inflammatory muscle illness in cats is treated and managed differently depending on the underlying cause and severity of the disease. Here is some usual muscle weakness in cats management and treatment options for cats:

  • Medications: Medications can help manage the symptoms of non-inflammatory muscle disease in cats. For example, corticosteroids may be prescribed to reduce inflammation, and pain medications may be given to manage discomfort.

  • Nutritional Supplements: Nutritional supplements, such as vitamin E, selenium, and omega-3 fatty acids, can help support muscle health and function in cats.

  • Physical Therapy: Physical therapy, such as range-of-motion exercises and massage, can assist in improving muscle tone and strength in cats with muscle illness.

  • Environmental Changes: Cats suffering from muscular illness may benefit from environmental changes such as easy access to food and water, litter boxes, and other essentials.

  • Surgery: Surgery may be required in some cases to remove a tumor or cure muscle damage.

  • Management of Underlying Conditions: If the feline muscle weakness is caused by an underlying condition, such as hyperthyroidism or renal disease, treating the underlying condition is critical to managing the muscle disease.

  • Supportive Care: Providing supportive care, such as monitoring the cat's weight and hydration levels, and ensuring that the cat is comfortable and pain-free, is also essential.

Prevention Tips

Some causes of non-inflammatory muscle disease in cats, such as genetic disorders, are unavoidable. However, cat owners can take some precautions to reduce the risk of muscle disease or manage the symptoms of the disease. Here are some tips for preventing non-inflammatory muscle disease in cats:

  • Provide a Nutritious Diet: A balanced and nutritious diet is essential to maintain muscle health in cats. Ensure that your cat's diet includes adequate amounts of protein, vitamins, and minerals.

  • Encourage Exercise: Regular exercise and playtime with toys help maintain muscle tone and prevent muscle atrophy in cats. Encourage your cat to play and exercise, but avoid excessive or severe and dangerous activities.

  • Keep the Environment Safe: Provide a safe and secure environment for your cat to minimize the risk of trauma or injury. Keep toxic substances, such as cleaning agents and plants, out of reach.

  • Monitor Your Cat's Health: Regular veterinary check-ups can help identify any health issues, including muscle disease, early. Monitor your cat's behavior, appetite, and physical condition, and report any changes to your veterinarian promptly.

  • Manage Underlying Conditions: If your cat has an underlying health condition that can lead to muscle disease, such as hyperthyroidism or renal disease, work closely with your veterinarian to manage the condition and prevent the development of muscle disease.

However, you may help lower the risk of non-inflammatory muscle illness in your cat and preserve their general health and well-being by adopting these preventive actions.
