Feline Cutaneous Asthenia: Managing Symptoms and Prevention Strategies

Feline Cutaneous Asthenia: Understanding the Significance of

Collagen and Skin Elasticity

As pet owners, we all want our furry companions to remain healthy and happy throughout their lives. Unfortunately, certain genetic mutations can predispose our beloved cats to various debilitating conditions, one of which is Feline Cutaneous Asthenia or Ehlers-Danlos Syndrome.

In this article, we will delve into the intricacies of this chronic ailment, the underlying causes, the symptoms, diagnosis, and potential treatments. What is Feline Cutaneous Asthenia?

Feline Cutaneous Asthenia (FCA) is a rare genetic disorder that affects the body’s ability to produce collagen, a vital protein responsible for providing strength, structure, and elasticity to the skin, ligaments, and other connective tissues. This crippling condition was first documented in Siamese and related breeds, but it can affect any feline breed.

FCA is also known as Ehlers-Danlos Syndrome, a similar disorder that affects humans and dogs. The disorder varies in severity, but the primary symptom is abnormal or deficient levels of collagen, which results in loose skin and ligament instability, leading to a range of dermatological and physical problems.

Symptoms and Types

The symptoms of Feline Cutaneous Asthenia are often present at birth or apparent in the juvenile stage, although some cases may develop later in life. The symptoms vary from cat to cat and can include:

– Saggy skin: The most noticeable symptom is a lack of skin elasticity, which causes the skin to appear loose and saggy.

The skin can appear droopy and wrinkly, especially around the eyes, face, neck, and belly. – Skin tears: The skin is more vulnerable to damage, and any physical contact may lead to cuts, bruising, and lacerations.

The wounds may take longer to heal, and they can lead to scar formation. – Swollen elbows: Cats with FCA may develop swollen elbows and hocks or ankles due to the constant rubbing of these joints against hard surfaces.

– Hematoma: Cats with FCA are more prone to forming hematomas, which are pockets of blood that form beneath the skin, usually after minor injuries caused by scratching or playing. – Lacerations: Feline Cutaneous Asthenia cats may develop deep skin tears due to ordinary grooming activities.

– Hernias: Hernias can occur due to the weakened elastic fibers of the ligaments.


Feline Cutaneous Asthenia is caused by a genetic mutation, which affects the formation of collagen. The disorder can be inherited in two different forms, with the dominant form being the most common, while the recessive form is rarer.

To inherit Feline Cutaneous Asthenia, a cat must inherit two copies of the mutated gene, one from each parent. A cat with one copy of the mutated gene is known as a carrier, and they will not develop the condition but can pass it on to their offspring.


Diagnosing Feline Cutaneous Asthenia can be tricky and requires a careful examination of the cat’s skin and joint structure. A veterinarian will use the Skin Extensibility Index (SEI) to measure the extent of skin stretching in affected cats.

This test involves pulling the skin taut and measuring the degree of extension. A cat with Feline Cutaneous Asthenia will have an extremely high SEI value, indicating that the skin stretches too easily.

Other tests such as microscopic examination, genetic testing, and skin patch tests may also be used to confirm the diagnosis.


Unfortunately, there is no known cure for Feline Cutaneous Asthenia. The condition is progressive, and the clinical symptoms tend to worsen with age.

In most instances, cats with severe symptoms may require euthanasia or will experience a reduced quality of life. Owners of cats with FCA must take elaborate precautions to minimize the risk of injury to their pets.

Regular vet visits, potential antibiotic treatment for infectious injuries, and keeping the cat indoors all the time to avoid injuries and exposure to harsh natural conditions are some of the measures that can be taken. One potential treatment option is Vitamin C supplementation, which has been shown to provide some benefit in promoting collagen formation and preventing skin and testicular atrophy.

At the same time, skin patch tests can provide valuable insights into the degree of skin sensitivity and the specific allergens that cause reactions in affected cats.

Collagen and Skin Elasticity

Collagen is essential for maintaining healthy skin, ligament structure, and bone health. The protein molecules form strong fibers that provide skin strength and elasticity and support the structural integrity of the ligaments and other connective tissues.

As a result, collagen plays a critical role in the health and wellbeing of all mammals, including cats. Feline Cutaneous Asthenia is caused by abnormal collagen synthesis, which hampers the formation of healthy protein fibers that provide structural support to the body and promote skin elasticity.

This abnormality leads to painful movements, ligament instability, skin droopiness, and low collagen levels, internally and externally.

Effects on Skin

The lack of collagen in cats with Feline Cutaneous Asthenia makes their skin more susceptible to injury, tearing, bruising, scarring, fish mouth wounds, and scar widening over time. There is an increased likelihood of injuries from play or scratches.

Existing wounds may take a more extended time to heal, and their resulting scars continue to enlarge over time.

Effects on Ligaments and Bones

Cats with Feline Cutaneous Asthenia have weakened ligaments that may lead to joint dislocation and bones popping out of place, making bones and joints painful to move. The lack of collagen also results in painful physical environments and painful dislocation at joints.

The condition can cause a lifetime of discomfort for our furry friends, which is why early diagnosis and treatment is critical.


Feline Cutaneous Asthenia is a rare and debilitating genetic disorder that affects cats. The condition can cause sagging skin, increase susceptibility to injury, increase scarring, and lead to decreased quality of life.

While there is no known cure for this debilitating disorder, early diagnosis, and preparatory measures can alleviate the severity of the symptoms. As pet parents, we must remain vigilant and watchful for signs of such genetic abnormalities in our feline friends to provide early treatment and safeguard their wellbeing.

Feline Cutaneous Asthenia: Exploring Management and

Prevention Strategies

Feline Cutaneous Asthenia (FCA), also known as Ehlers-Danlos Syndrome (EDS), is a debilitating genetic disorder that affects a cat’s ability to produce healthy collagen protein. The lack of collagen leads to loose skin and ligament instability, resulting in various dermatological and musculoskeletal problems.

While there is no known cure for the condition, early diagnosis, management, and preventative measures can help improve the quality of life for cats with Feline Cutaneous Asthenia. In this article, we will explore several treatment alternatives and prevention strategies to help manage and prevent FCA.

Treatment Alternatives Besides Euthanasia

Cats with Feline Cutaneous Asthenia are likely to experience injuries due to their weak connective tissues. It is crucial to address any wounds immediately to prevent secondary infections, which can further exacerbate the condition.

Wound repair and antibiotics are essential for treating injuries and ensuring that cats don’t develop any severe infections. Supplementing a cat’s diet with Vitamin C can also promote collagen production and delay the onset of Feline Cutaneous Asthenia symptoms.

However, it is essential to consult a veterinarian before administering any supplements. Additionally, skin patch tests can help identify potential allergens that can exacerbate the condition.

Cats with a reaction to an allergen can benefit from avoiding those allergens or administering appropriate allergy medication.

Prevention Strategies

Preventing Feline Cutaneous Asthenia is challenging, but there are several effective strategies that can help minimize the risk of developing the condition. Here are some preventative measures to consider:


Isolation: Isolating cats with Feline Cutaneous Asthenia can help minimize the risk of developing secondary infections or sustaining injuries. By keeping them indoors and minimizing their physical activity, they are less likely to injure themselves.

It is also important to keep them away from other cats to avoid transmitting infections. 2.

Declawing: Cats with Feline Cutaneous Asthenia must not have claws as they pose a higher risk of injury during daily activities. Declawing is necessary for cats with FCA to reduce the risk of injury and prevent further damage to their loose skin.

3. Avoiding allergens: Allergens can exacerbate skin inflammation, leading to increased skin irritation, itching, and scratching.

Preventing cats from coming into contact with known allergens can minimize the risk of triggering Feline Cutaneous Asthenia symptoms. Keep a log of allergies and allergens that have provoked an immune response, and keep your home environment free from these irritants.

4. Sharp corners: Cats with FCA can easily experience dislocations or acquire wounds from sharp edges or corners within their environment.

It is essential to modify their environment to ensure that they navigate comfortably and efficiently without experiencing discomfort or sustaining injuries. 5.

Careful handling: When handling cats with Feline Cutaneous Asthenia, extra care should be taken to avoid accidentally causing injury. Cats with FCA can easily dislocate a joint when picked up by the wrong angle or with too much force.

Using a soft bristle brush or grooming mitt is gentler and less invasive than using a metal comb or slicker brush. It’s also wise to avoid extensive play sessions or too much physical activity.

6. Informing visitors: Communicating your cat’s medical situation and needs can go a long way in preventing accidents around cats with Feline Cutaneous Asthenia.

Explain to visitors that your cat requires special handling and avoidance of excessive physical activity.


Neutering may not be a prevention or treatment strategy, but it can significantly reduce the incidence of FCA. The mutated gene that causes the disorder is passed from parents to offspring.

Therefore, by neutering cats with Feline Cutaneous Asthenia, they can no longer reproduce. Along with preventing genetic transmission, neutering also ensures that cats with FCA do not have to endure the gestational and birthing phases, which are problematic without adequate collagen.


Feline Cutaneous Asthenia is a genetic disorder that causes various physical and dermatological problems, significantly impacting a cat’s quality of life. There is no known cure for this condition, but early diagnosis, management, and preventative measures can help alleviate symptoms, reduce the incidence of injuries, and improve the overall health of cats with FCA.

By employing careful handling, isolation, and the appropriate preventative measures outlined in this article, you can mitigate the risks and provide a healthy, happy life for your feline friend. Feline Cutaneous Asthenia, or Ehlers-Danlos Syndrome, is a debilitating genetic disorder that affects a feline’s ability to produce collagen, leading to loose skin and ligament instability.

While there is no known cure for the condition, there are some treatment alternatives and prevention strategies that can help manage and prevent Feline Cutaneous Asthenia. Ensuring wound repair and administering antibiotics and Vitamin C can help alleviate symptoms, while isolation, declawing, avoiding allergens, avoiding sharp corners, using careful handling, informing visitors, and neutering can help reduce the risk of injury.

By being aware of the available options and understanding these preventative steps, cat owners can improve their pet’s quality of life and promote better health.
