Swollen, weeping skin areas, also known as hives or urticaria, are itchy, raised skin changes that can occur in cats. These reactions are usually allergic and lead to acute inflammation of the skin.

Can Occur with the Following Diseases:

Basics and possible causes

A cat’s skin is an essential organ that protects it from environmental influences and forms a barrier against infections. As with humans, a cat’s skin can also react to certain substances from the environment or its diet. An oversensitive reaction of the immune system can lead to swelling and itching.

Hives in cats are often triggered by allergens such as pollen, dust mites, mold, or certain foods. Insect bites, such as those from fleas or mosquitoes, can also cause such a reaction. Contact with chemical substances, such as cleaning agents or perfumes, can also be the trigger.

Another possible reason for the occurrence of hives is stress and anxiety. In some cats, psychological stress can lead to physical symptoms, including skin reactions. In rare cases, medications or vaccinations can also trigger an allergic reaction in the form of hives.

Typical accompanying symptoms

  • Itching: The cat constantly scratches the affected areas, which indicates intense itching.

  • Redness: The skin appears reddened, indicating an inflammatory reaction.

  • Swelling: Raised bumps or wheals are visible on the skin.

  • Oozing: The affected skin areas may secrete fluid.

  • Skin rash: A patchy or granular rash may occur.

  • Skin changes: If it persists for a longer period of time, crusts or scales may form.

  • Behavioral changes: The cat may appear restless or show signs of discomfort.

When to visit the vet?

It is advisable to consult a veterinarian if the hives occur suddenly and do not subside within a few hours, or if the cat shows signs of respiratory distress. Veterinary advice should also be sought immediately if the affected skin areas are severely weeping or become infected.

A visit to the veterinarian is also necessary if your cat shows additional symptoms such as vomiting, diarrhea, or lethargy, as this could indicate a more serious allergic reaction. A thorough examination is also necessary for recurring or chronic skin problems.

A quick intervention is important to minimize the risk of secondary infections and to relieve the itching, which can lead to increased scratching and further skin injuries.

Symptom recognition for animal owners and veterinary diagnostic procedures

As a pet owner, you should pay attention to signs of hives, especially if the cat is scratching or licking excessively. The affected skin areas are often easy to recognize because they are swollen and reddened. It can be helpful to determine whether a specific trigger, such as a new food or a change in the environment, correlates with the occurrence of the symptoms.

The veterinarian will take a thorough anamnesis to identify possible triggers. This includes information about new foods, changes in the household, or the use of cleaning agents. A physical examination of the cat will be performed to assess the condition of the skin.

For diagnosis, the veterinarian may order skin tests or blood tests to identify specific allergens. In some cases, a biopsy of the skin may be necessary to rule out other skin diseases.

What can pet owners do and professional therapy options

To relieve the itching and swelling, the pet owner can gently treat the affected skin areas with a cool, moist compress. This can help to reduce the inflammation and provide relief to the cat.

It is important to prevent the cat from scratching or licking to avoid worsening the symptoms. A neck collar or a protective suit can be helpful to restrict access to the affected areas.

If the hives were triggered by a known allergen, contact with it should be avoided. This may mean changing the food or ensuring that the cat does not come into contact with certain plants or chemicals.

In consultation with the veterinarian, antihistamines or anti-inflammatory drugs can be administered to relieve the symptoms. However, these should only be used under veterinary guidance, as not all medications are suitable for cats.

Regular coat care and keeping the environment clean can also help to reduce the risk of skin problems. A balanced diet that is rich in essential fatty acids can support skin health and strengthen the cat’s immune system.

Outlook on current research

Current research on swollen, weeping skin areas in cats, known as hives or urticaria, focuses on the role of the immune system and the molecular mechanisms that lead to these symptoms. Scientists are particularly investigating the role of mast cells, which release histamine and other inflammatory mediators during allergic reactions. These cells are crucial for the development of hives, as their activation and degranulation lead to the characteristic swelling and itching.

Another area of research is the genetic predisposition in cats. Genetic studies aim to identify specific genes that make cats more susceptible to skin reactions. These findings could lead to more targeted therapies in the future by taking into account the individual genetic differences in cats.

Innovative treatment approaches are also being explored. These include the development of new antihistamines specifically for cats and the investigation of immunomodulators that could stabilize the cat’s immune system to prevent excessive reactions. Some studies are looking at the use of biologics that specifically target the molecules involved in the development of hives.

Research into environmental factors that can trigger hives in cats is also gaining importance. Scientists are investigating the influence of allergens in food, in the air, and in the cat’s environment. These findings could help to develop preventive measures that reduce the risk of hives occurring.

Another interesting aspect of the research is the investigation of the role of the skin and intestinal microbiome in the development of hives. Studies suggest that an imbalance in the microbial composition could influence the susceptibility to skin reactions. Manipulation of the microbiome through probiotics or prebiotics could represent a complementary therapy option in the future.

Future research will focus on better understanding the underlying mechanisms of allergic reactions and improving the development of diagnostic tests that enable early detection of hives. Such progress could promote personalized medicine for cats, which is individually tailored to their specific allergic reactions.

Finally, researchers are investigating the long-term effects of hives on the health and well-being of cats. Chronic or recurrent hives can not only impair the quality of life of the animals but also lead to secondary infections and other complications. These investigations are crucial to improve the management strategy for affected cats.
