If a cat itches until it hurts, this may be a symptom of an allergic reaction, the presence of helminths, lichen, skin parasites, or a disease of the endocrine system. Associated symptoms include itchy skin, hair loss and red spots on the skin. If any deviations in health occur, the owner should take the pet to the veterinarian. The doctor will diagnose, prescribe therapy and give preventive recommendations.
According to veterinarian statistics, food allergies in cats account for 1% of cases of skin lesions.
Causes of itching in the head and neck area in cats
Cats scratch their necks until they hurt for a variety of reasons. This behavior is provoked by external factors, ectoparasites and a number of diseases of varying degrees of danger. The largest number of cases are due to allergies and insect parasites. A smaller percentage of the probability is associated with viral, autoimmune and other diseases.
Ectoparasitosis
Otodectes cynotis, or ear scabies, is caused by mites. They settle in the ears or ear canal and cause severe itching in the cat. As a result, she regularly shakes her head and scratches her ears until they hurt. It is transmitted by contact and affects mainly young animals.
Notoedrosis or pruritic scabies develops against the background of Notoedres cati tick bites. The disease is characterized by inflammation of the scalp, hair loss and severe itching. An infected cat constantly scratches its head until sores appear.
Important! Notoedres cati itches spread from cats to other animals and even humans. For some time they cause pseudo-scabies and then go away, since there are no favorable conditions for life.
Cheyletiellosis, or wandering scabies, is caused by Cheyletiella mites. The fact that a cat has these parasites is indicated by severe itching and fine dandruff. The disease often spreads to humans and causes an itchy rash.
Demodectic mange or ironworm is the result of exposure to mites of the genus Demodex. They develop their vital activity in the sebaceous glands and hair follicles. As a result, bald patches of skin and sores appear on the cats’ faces. The areas most commonly affected are the areas around the eyes and mouth, as well as the front legs.
Fleas are a common cause of scratching on the neck and other parts of the body. They parasitize primarily on cats and dogs. They can also temporarily transfer to humans. When infected with them, a large number of black crumbs appear under the fur of pets. These flea droppings are especially noticeable in the lumbar and back areas.
The animals themselves itch very much to the point of soreness, as they experience severe itching at the bite sites.
Allergies
A common reason why a cat scratches itself until it hurts is allergies. It implies an abnormal reaction of the body to a stimulus. When first hit, protective cells create an antidote and “remember” the allergen. And if it penetrates again, a violent reaction occurs in the body. It leads to inflammation, itching and other symptoms.
Allergies cause several diseases in cats:
- atopic dermatitis;
- flea dermatitis;
- food allergies;
- contact dermatitis.
Flea dermatitis
Flea dermatitis is a common reason why a cat scratches itself until it hurts. When one flea bites, it releases a special anticoagulant into the cat's skin. This substance prevents blood clotting. The pet becomes sensitized to it. And the body reacts to the bites of other fleas in the form of inflammatory processes, rashes and papules.
The affected areas are very itchy. The cat begins to behave restlessly and reacts nervously to touch. This type of dermatitis occurs in two forms: chronic and latent. In the first case, alopecia (foci of baldness) and nodules with flea feces develop on the body. The second is characterized by the appearance of papules with a red rim.
The cat begins to tear them apart until they hurt. Often secondary infection is associated with wounds.
Atopic dermatitis
The disease is typical for young animals aged 1 to 3 years. The main reason for its appearance is the uncontrolled selection of cats. As a result, animals develop allergies to dust and pollen. In this case, it is almost impossible to identify the allergen.
Important! Atopic dermatitis has no cure; cats will regularly scratch their skin until it hurts. The action of therapy is aimed at suppressing symptoms.
Dermatitis in cats manifests itself with the following symptoms:
- the appearance of dandruff on the withers and back;
- hair loss;
- labored breathing;
- discharge from the eyes and nose;
- cough;
- profuse salivation.
Contact dermatitis
This allergy is similar in symptoms to atopic dermatitis. It often manifests itself when the pet comes into contact with household chemicals, toilet filler, the hair of other animals, and flea products. Contact allergies are manifested by severe itching, flaking of the skin and a small rash. Often a cat itches until it hurts. And this increases the risk of secondary infections.
Food allergies
Allergens can accumulate in the body of animals. With their regular consumption, health problems begin. Food allergies are characterized by:
- the appearance of a rash on the cat’s neck and head;
- hair loss;
- the appearance of dandruff;
- inflammation of the eyelids;
- unpleasant odor from the mouth.
Important! Symptoms of food allergies in cats are often accompanied by vomiting and indigestion.
A common cause of food allergies is feeding cats salted, fried, smoked and other prohibited foods from the table. Mixed feeding with industrial feed and natural products also contributes to its appearance.
Why you can't stop itching
If you have not yet visited the veterinarian, you should not smear the sores with anything at all - this will distort the results of scrapings and tests, which will complicate the diagnosis. You should not immediately offer your animal antihistamines - firstly, you may not guess the dosage, and secondly, the blood test will be invalid.
Once the veterinarian has prescribed medications and ointments, there is no need to relieve itching - most medications already contain substances that reduce discomfort.
Finally, anti-itch medications in humans can cause allergies in cats, which will only make the problem worse.
Skin infections
Scratched cat sores on the neck and head in some cases occur due to infectious diseases. Cats with access to the outdoors are especially susceptible to them. When a bacterial infection of the skin occurs, one of two forms develops:
- Dry. Dry crusts, dandruff and scabs form on your cat's neck.
- Wet. It is characterized by the appearance of blisters and ulcers with liquid contents inside.
Animals with sensitive skin are predisposed to eczema. It develops through prolonged contact with flea collars, harnesses, after insect bites and skin parasites.
Important! Diabetes mellitus, neuropathy and hormonal changes contribute to the appearance of eczema.
A rash and blisters appear on the pet's body. Severe itching leads to the cat scratching its neck until it bleeds, and sores appear that do not go away for a long time. To eliminate eczema, antibacterial therapy, various ointments and powders are prescribed.
Viral dermatoses
Cat scratching on the skin is also characteristic of viral dermatoses. The herpes virus affects the eyes and respiratory tract of the animal, often manifesting itself as skin lesions. They are often localized in the area of the nose and eyes, less often on the paws and stomach.
Feline herpes is characterized by:
- bloody stains;
- small rash;
- swelling of the skin;
- small scabs on the neck, sores on the head.
Skin changes appear 1.5 weeks after the disappearance of conjunctivitis and other characteristic symptoms.
Cowpox or poxvirus is a rare disease. It can enter the cat's body through the bites of small rodents. It manifests itself as skin lesions in the form of nodules and small ulcers. With good immunity, it goes away on its own. In weakened animals there is a risk of developing a severe form.
Autoimmune dermatoses
Autoimmune diseases are characterized by an abnormal reaction of the immune system to its own tissues and cells. Skin manifestations on the body of cats are characteristic of several diseases:
- Common pemphigus. It is characterized by the development of ulcers in cats around the mouth and in its cavity itself. Involves long and difficult treatment. It often ends critically for animals.
- Erythematous pemphigus. Crusts, ulcers, blisters, sores and other lesions are concentrated in the area of the animal’s nose and bridge of the nose. Sometimes the disease is accompanied by a change in skin color.
- Pemphigus foliaceus. The main symptom is the appearance of large pustules on the skin near the mouth and ears. Associated signs in cats include elevated body temperature, refusal to eat, and apathy.
- Systemic lupus erythematosus. It affects all systems and organs of the animal. Wounds on the scalp manifest themselves through depigmentation of the skin, the development of a rash and the subsequent formation of ulcers.
Bacterial or fungal inflammation
Various opportunistic microorganisms living on your pet's skin do not harm a healthy animal. But if your cat’s body has been weakened, for example, due to some disease or lack of vitamins, then the population of “harmful” fungi and bacteria increases, causing the cat’s skin condition and general well-being to deteriorate.
The doctor will check for inflammation caused by fungus or bacteria and also conduct a smear examination. As a rule, this inflammation is not the main cause of the disease.
Skin tumors
Skin neoplasms are in first place among oncological diseases in animals. By their nature, they are also divided into benign and malignant forms.
The first includes:
- Basalioma. The sore is a pigmented dome-shaped tumor. At the point where it appears, the animal loses its hair.
- Cutaneous histiocytoma. Characterized by a rapidly growing tumor under the skin. A rare pathology for cats.
Malignant skin tumors develop in two cases:
- Squamous cell carcinoma. The disease manifests itself in the nose, eyelids and ears. Metastases spread through the lymphatic system.
- Basal cell carcinoma. Develops from basal cells of the skin. Characterized by rapid growth and a high probability of metastasis.
The cat itches, chews itself, constantly licks itself: is this normal?
If an animal itches due to severe itching, then with sharp claws it damages the skin, causing infection.
During severe itching, severe irritation of pain receptors occurs, because of this the animal begins to lick and chew itself. The skin on the affected area turns red and wounds appear. The reasons for this condition are different. To relieve the symptom and understand what to do, the pet must be shown to a doctor.
When it's ok
Cats are clean creatures. They wash themselves after sleep and after eating. If your pet eats natural food, then after licking the fur it will smell like the food it ate.
The smell of eaten herring is especially strong. If the animal licks itself too much, then it needs a medical examination.
Signs of a pathological condition of an animal
The painful condition can be determined by itching of the skin or ears. With skin itching, you can notice how the cat itches a lot and tries to bite the source of its anxiety from under the skin with its teeth.
When the itching is localized in the ear, the cat tries to stick its paw deep into it to scratch.
During this period you may notice:
- constant scratching of the body with a plaintive meow;
- pronounced biting of the skin;
- hair loss, deterioration of its appearance;
- the appearance of dandruff, oily scales;
- the skin is covered with ulcers or red rashes in the form of small spots;
- parasites or their excrement are visible on the skin.
It is easy to help an animal if you notice deviations in behavior in time and take him to the clinic. An advanced disease is more difficult to cure.
History taking
Diagnostics will help you understand why your cat scratches its neck and what caused the sores. But before carrying it out, the veterinarian needs to collect an anamnesis.
Age and breed
A kitten up to one year old is susceptible to skin and subcutaneous parasites. Young animals suffer predominantly from allergic reactions. If an elderly cat scratches its neck until it bleeds and hurts, this may be due to autoimmune dermatoses.
The breed of the animal also leaves its mark. Persian cats are prone to dermatophytosis and dermatitis, while Sphynx cats are prone to allergies and neoplasms.
Lifestyle
A large number of animals in one area, access to the street, participation in cat shows and other factors increase the risk of infection with parasites and viral diseases.
Seasonality
Allergies to pollen, bee or mosquito bites have a pronounced seasonality. Flea dermatitis in cats manifests itself regardless of the time of year. But it is most common in August-September.
Prevention of allergic dermatitis caused by fleas
Increased sensitivity to flea saliva is an individual feature of the immune system of an allergic cat, so it is impossible to get rid of it once and for all. However, the likelihood of developing dermatitis becomes many times less if you follow the following rules:
- avoid contact with flea-infested animals;
- remove outerwear and outdoor shoes away from pets;
- regularly inspect the wool for the presence of insects and traces of their vital activity;
- keep the apartment clean and conduct a weekly inspection of cat litter and toys;
- use anti-flea collars or drops;
- carry out regular deworming, since intestinal parasites provoke allergic reactions;
- for bathing, use special hypoallergenic zoo shampoos;
- Compose your cat’s diet correctly and, if necessary, use food supplements and vitamin preparations.

Diagnostic methods
Diagnostics will help determine why a cat scratches its neck until it hurts. The doctor prescribes one or more methods:
- Combing wool. A fine comb is used for this. The procedure allows you to see fleas, lice and skin mites on cats. Can be done independently at home.
- Trichogramma. Determines the presence of spores and eggs on the hair shaft.
- Examination of earwax under a microscope. It is carried out if otodectosis is suspected.
- Wood's lamp. Shows the glow of spores on the skin of an animal from certain types of fungus.
- Cytological examination. The veterinarian recommends this to detect yeast and bacterial infections.
- Allergy test. Prescribed for confirmed atopic allergies in cats.
- Skin scraping. Detects ticks, their larvae, and spores.
- Elimination diet. Prescribed by a veterinarian to determine the allergen for food allergies.
- Fungal culture. An effective method for dermatophytes.
Treatment: how to act correctly?
When a cat itches due to a food allergy, treatment depends solely on the cause of the disease - poor quality food. Other types of allergic reactions should also be treated by eliminating the allergens. If your cat is itching a lot, you can relieve the symptoms of itching with Stop-Itching. When infected with skin parasites, the cat is washed with antiparasitic shampoos - “Bars”, “Advantage”, “Pride”. Flea sprays “Frontline”, “Advocate”, “Bolfo”, and a collar “Foresto” help. For lichen and fungi, “Griseofulvin”, “Terbinafine”, “Itraconazole”, “Fungin”, “Zoomicol” are effective. Endocrine disorders can be treated with hormonal drugs, which the veterinarian prescribes individually.
Depending on the reasons that cause itching, medications are used, for example, Enwire will help against worms.
If a cat has an itchy back or other part of the body due to helminthiasis, the drugs Drontal, Enwire, Stronghold, and Profender are recommended. If your cat often itches near its ears, anti-mite drops “Barrier”, “Anandin”, and “Advocate” are suitable. When the causes of itching are eliminated, treatment of the cat includes the use of zinc ointment and Levomekol liniment, which promote the regeneration of sores. “Purified, mineralized sulfur” and vitamin A preparations are effective for restoring the skin and coat. You can also make lotions from decoctions of chamomile, string, and St. John's wort.
