Analysis of Itching Symptoms in Cats: Potential Causes and Solutions
A fan asked: My cat has been unusually itchy lately, and his tail gets thicker when I brush him. Although the dandruff disappeared after using a medicated bath, the itching has persisted for six or seven months.
The doctor ruled out fungal infection and ear mites, and suspected it might be a mite allergy, recommending the use of anti-allergy medication.

01 Possible causes of itching in cats
Cat itching can be caused by a variety of factors, including allergic reactions to environmental factors, food, parasites, etc.
Especially when a cat experiences persistent itching without obvious skin lesions, the possibility of food-related or environmental allergies is relatively high.
02 Allergies and Itching
Allergies are one of the common causes of itching in cats, manifesting as excessive sensitivity to certain food ingredients or substances in the environment such as dust and pollen.
Since the fan mentioned that no blood allergy test had been conducted, it was impossible to accurately determine whether it was caused by an allergy, but this is still one of the reasons for the high suspicion.
03 Daily Care and Observation
Observing a cat's behavior during grooming, such as a ruffled tail, does not necessarily indicate a decline in bodily functions; it is more likely a stress response triggered by itching.
In addition, a cat's initiative to seek grooming may be because the brief stimulation can relieve itching, rather than necessarily indicating comfort and enjoyment.
04 Adjustments to Living Environment and Diet
Given that the cat had a history of gastrointestinal discomfort before the onset of the disease and had been consuming a single brand of canned food for a long time, there may be a risk of food allergies.
We recommend trying a hypoallergenic prescription canned food and ensuring your cat's living environment is clean to reduce potential exposure to allergens.
05 Medical Intervention and Drug Treatment
In the absence of a clear diagnosis, you can first use anti-allergy medications to control the itching symptoms as advised by your doctor.
At the same time, considering the cat's age and health condition, it is advisable to administer necessary vaccinations and deworming to prevent related diseases.

06 Comprehensive Treatment Plan
Depending on the cat's specific situation, we recommend a comprehensive physical examination, including blood tests to confirm the allergy issue, and close monitoring of the cat's behavioral changes and dietary responses.
In addition, in daily grooming, choose a suitable comb and grooming method to avoid irritation that causes frizz.
