In cats, the term “thickened nails” refers to an abnormal thickening of the claws, which can often be accompanied by other changes such as discoloration or an irregular structure. This thickening can indicate various health problems and should not be ignored.

Can Occur with the Following Diseases:

Basics and possible causes

Cat claws consist of several layers of keratin, a hard protein. Normally, the outer layer of the claw wears down through scratching, exposing the sharp layer underneath. A thickened claw may indicate that this natural wear process is disrupted.

One of the most common causes of thickened nails in cats is lack of activity. Cats that do not have sufficient opportunity to use their claws, whether by scratching or climbing, may develop a thickening of the claws. House cats that have less access to suitable scratching surfaces are particularly at risk.

Infections, both bacterial and fungal, can also lead to thickened claws. An infection can weaken the structure of the claw and lead to an excessive production of keratin, which thickens the claw.

Hormonal disorders, such as an over- or underactive thyroid, can also affect the health of the claws. These conditions can lead to systemic changes that thicken the claws.

Another possible cause is trauma or injury. A damaged claw may regrow unevenly, leading to thickening. Injuries can result from accidents or inadequate care.

Typical accompanying symptoms

  • Pain or discomfort: Cats with thickened claws may show signs of pain, especially when walking or trying to use their claws. They may also show signs of discomfort when the claws are touched or examined.

  • Changes in gait: A cat with thickened claws may show an unusual gait or try to shift weight off the affected paws to avoid pain.

  • Claw problems: In addition to thickening, discoloration or cracks may also occur in the claws. The claws may become brittle and break more easily.

  • Behavioral changes: Cats may withdraw or be less active to avoid pain or discomfort. They may also react aggressively if someone tries to touch their paws.

  • Inflammatory conditions: A bacterial or fungal infection can cause inflammatory conditions around the claw. This can lead to redness, swelling, or pus.

When to visit the vet?

A visit to the vet is essential if the cat shows signs of pain, behaves unusually, or if the thickened claws are accompanied by other symptoms such as inflammatory conditions or infections. Early diagnosis can help prevent more serious health problems.

A veterinarian should also be consulted if a cat has difficulty walking or refuses to use its claws. It is important to determine the cause of the thickening in order to find appropriate treatment.

If the claw is severely thickened and deformed, this could indicate a serious underlying condition that requires a comprehensive veterinary examination. In such cases, the veterinarian can perform special diagnostic tests to determine the cause.

Symptom recognition for animal owners and veterinary diagnostic procedures

For the pet owner, the detection of thickened claws can initially be done by regularly examining the paws. Pay attention to visible changes in the structure and color of the claws, as well as signs of discomfort in your cat.

A veterinarian will usually perform a thorough physical examination to determine if there are other health problems. This may also include examining the claws under a microscope to identify infections or other structural changes.

In addition, blood tests may be necessary to rule out hormonal imbalances or other systemic diseases. In some cases, a culture analysis could also be performed to confirm the presence of bacteria or fungi.

What can pet owners do and professional therapy options

The pet owner can take some measures to relieve the symptoms and prevent further damage. Make sure your cat has access to suitable scratching opportunities to support the natural wear process of the claws.

It is important to check and trim your cat’s claws regularly if they are excessively long. This can help reduce the risk of injury and further thickening.

If an infection is suspected, the affected area should be kept clean and dry until veterinary treatment can be given. Avoid using home remedies without consulting a veterinarian, as these may not be appropriate.

In any case, it is important to follow the veterinarian’s instructions and arrange regular check-ups to ensure that your cat’s claw health is monitored.

Outlook on current research

Current research on thickened nails in cats is increasingly focused on the underlying biological processes that lead to morphological changes in the claws. Scientists are particularly investigating the role of keratin, the main component of nails, and its abnormal cornification, which can lead to thickening. It is believed that certain genetic factors can influence the production of keratin and thus contribute to structural changes in the claws.

Another aspect of the research focuses on the biomechanical properties of thickened claws. Researchers are analyzing how the thickening affects the functionality and behavior of the cat. Initial results suggest that thickened claws can impair the cat’s gripping and climbing ability, leading to an altered movement pattern. These biomechanical studies are particularly important for developing appropriate therapeutic measures that improve not only the symptoms but also the quality of life of the affected cats.

In addition, the influence of environmental factors on the occurrence of thickened nails is being investigated. Researchers are interested in how diet, habitat, and care practices can affect the health of the claws. An inadequate supply of certain nutrients, such as biotin or essential fatty acids, could increase the risk of developing thickened claws. In this context, the effects of stress and psychological factors on claw health are also being investigated, as these could also play a role.

Innovative diagnostic technologies, such as high-resolution imaging and molecular analysis techniques, are also being used in research to enable more accurate diagnoses. These technologies help to analyze the structure and composition of thickened claws in detail and to identify differences from normal claws. Such analyses could form the basis for the development of new treatment methods in the future.

An emerging area of research is also the investigation of the microbiota on and around the claws. There is evidence that microbial communities could play a role in the health of the claws. The connection between a disturbed microbiota and the occurrence of thickened nails is currently being intensively researched in order to better understand the possible effects on the prevention and treatment of such symptoms.

Frequently asked questions

  1. Why are my cat’s nails thickened? Thickened nails in cats can be caused by various factors, including genetic predisposition, nutritional deficiencies, environmental factors, or age-related changes. Often, they are a symptom of underlying health problems that require veterinary examination.

  2. How do I know if my cat’s nails are thickened? Thickened nails are often more difficult to cut because they are thicker and harder than normal claws. They may also be more irregular in shape and cause the cat discomfort or difficulty walking.

  3. Can thickened nails cause my cat pain? Yes, thickened nails can cause pain, especially if they grow into the soft tissue of the paws or pressure is exerted on the claws when walking on uneven surfaces.

  4. Are thickened nails a sign of a serious illness? Thickened nails can be a sign of more serious health problems, such as skin diseases, fungal infections, or autoimmune diseases. However, an accurate diagnosis requires an examination by a veterinarian.

  5. Can I treat my cat’s thickened nails myself? It is advisable to leave the treatment of thickened nails to a veterinarian, as improper care can lead to further complications. A professional examination can determine the cause and initiate appropriate treatment.

  6. How can I reduce the risk of thickened nails in my cat? A balanced diet, regular claw care, and a stress-free environment are important factors that can help minimize the risk of thickened nails. Regular veterinary examinations also help to identify any problems early on.

  7. Are there special products for the care of thickened nails in cats? Yes, there are special products such as claw files and nail care oils that have been developed for the care of thickened nails. However, these products should ideally be used in consultation with a veterinarian.

  8. How often should I check my cat’s nails? It is recommended to check your cat’s nails at least once a month. A veterinarian should be consulted if there are signs of thickening or other abnormalities.

  9. Can thickened nails affect my cat’s behavior? Yes, thickened nails can affect a cat’s behavior, as it may be less active or show pain avoidance tactics, such as avoiding jumping or climbing.

  10. Are certain cat breeds more prone to thickened nails? There is evidence that certain breeds may be more prone to thickened nails due to genetic factors. However, a comprehensive study would be necessary to confirm this definitively.
