Increased personal hygiene (licking) in cats is a condition in which a cat licks more frequently or intensely than normal to clean its fur or for other reasons that may indicate health or psychological problems.

Can Occur with the Following Diseases:

Basics and possible causes

Cats typically spend a significant portion of their day grooming. This is normal behavior that helps keep the coat clean and free of parasites, as well as regulating temperature. However, increased personal hygiene can indicate underlying health or psychological issues.

A common cause of excessive licking is stress or anxiety. Changes in the environment, such as moving to a new home, introducing a new pet or family member, or even just changes in the daily routine, can trigger stress in cats. This stress can manifest as increased personal hygiene.

Another cause can be pruritus, an uncomfortable itching of the skin that can be caused by allergies, parasites such as fleas or mites, or skin infections. Cats try to relieve the itching by licking intensely, which can often lead to skin irritation or injury.

Pain or discomfort, for example from arthritis or injuries, can also cause a cat to lick more. In such cases, the licking often focuses on the affected area of the body.

Some cats show increased licking as a form of compulsive behavior that can be triggered by boredom or frustration. This is especially common in indoor cats who do not have enough to do.

Typical accompanying symptoms

  • Skin irritation: Redness, swelling or wounds often occur in the areas where the cat licks intensely.

  • Hair loss: Excessive licking can lead to bald spots in the coat, especially in the abdominal area, on the legs or on the flanks.

  • Behavioral changes: The cat may appear restless or irritated, especially if it is suffering from itching or pain.

  • Loss of appetite: With severe stress or physical discomfort, the cat’s appetite may be reduced.

  • Increased meowing: A cat that feels unwell or has pain may meow more often to attract attention.

  • Lethargy: If the increased licking is caused by an illness, the cat may also appear lethargic.

When to visit the vet?

It is important to see a veterinarian if the increased licking persists for several days or if the cat’s skin becomes inflamed or injured. A visit to the vet is also advisable if the cat shows other symptoms that indicate pain, discomfort or stress, such as loss of appetite or behavioral changes.

If the increased personal hygiene is accompanied by visible weight loss, diarrhea or vomiting, a veterinarian should also be consulted immediately, as this may indicate more serious health problems.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for the pet owner to observe the frequency and intensity of their cat’s personal hygiene. Note when and how often the cat licks and whether there are specific triggers, such as stressful situations or changes in the environment.

The veterinarian will perform a thorough physical examination of the cat to look for signs of skin irritation, infections or parasites. Blood tests, allergy tests or skin biopsies may also be necessary to identify underlying health problems.

In some cases, it may be necessary to carry out a behavioral analysis to determine whether psychological factors such as stress or compulsive behavior play a role. The veterinarian will also assess the cat’s living conditions to identify possible stressors.

What can pet owners do and professional therapy options

As a pet owner, you can take measures to provide your cat with immediate relief. Make sure your cat’s environment is quiet and avoid sudden changes that could trigger stress.

Regular grooming with a soft comb can help remove loose hair and stimulate the skin, which can reduce itching. Make sure your cat is regularly dewormed and treated for fleas to prevent parasite infestation.

If you suspect that boredom is the cause of your cat’s behavior, try offering more play and activity opportunities. Intelligence toys and regular playtimes can help challenge your cat mentally and physically.

If an allergy is suspected, a change in diet can help. Discuss the possibility of a hypoallergenic diet or other dietary adjustments with your veterinarian.

In situations where stress plays a role, calming supplements or pheromone products for cats can be useful. These can help lower your cat’s stress levels and normalize behavior.

Outlook on current research

Research on increased licking in cats is currently focused on understanding the behavioral causes as well as the neurobiological mechanisms underlying this symptom. Scientists have found that increased grooming can be an indicator of stress or anxiety. Studies show that cats that lick excessively often have an increase in cortisol levels, which is an indication of increased stress. Recent research is examining the connection between environmental factors, such as changes in the household or the introduction of new pets, and increased licking behavior.

Another research aspect lies in the area of genetic predisposition. Some cat breeds appear to be more susceptible to exaggerated grooming, suggesting that genetic factors may play a role. Researchers are currently investigating specific genes associated with compulsive behavior to identify potential genetic markers that could influence the behavior.

There are also studies that deal with the role of neurotransmitters in the brain and their influence on licking behavior. In particular, serotonin, a neurotransmitter associated with the regulation of moods, is in focus. Some studies have shown that administering medications that affect serotonin levels can help reduce compulsive licking, supporting the hypothesis that chemical imbalances in the brain may play a role.

Current research is also intensively involved in the development of new therapeutic approaches to treat this symptom. In addition to drug treatments, the effectiveness of behavioral therapies and environmental adjustments is also being investigated. Initial results suggest that a combination of therapy and environmental management may be more effective than individual approaches.

In addition, the role of nutrition as a potential influencing factor on licking behavior is being explored. Some studies suggest that certain nutritional deficiencies or excesses could affect behavior. Nutritional interventions that balance the content of certain nutrients are another focus of research with the aim of improving the well-being of cats and alleviating the symptom.
