Itchy cats

Signs of being itchy and skin disease are two of the most common reasons that people take their cats to the vet. There are many different problems that may cause your cat to itch. 

Some conditions are more common in different breeds or at different ages. Depending on the cause and condition, cats may need lifelong treatment. If your cat becomes itchy, consult a vet for advice as soon as possible. If left untreated, itching can worsen and lead to severe self-trauma, hair loss, and skin infections.


What to do

What to do if your cat is itchy

Depending on how severe the signs are, different treatment options may be available.

  • Mild itching is when the itch does not happen often. This can often be treated at home, depending on the cause. Skin supplements, diet changes, parasite control, and topical skin treatments can all be useful. Speak to our Joii vets for more information.
  • When your cat is constantly scratching, we describe this as moderate or severe itching. They will stop what they are doing, such as eating or sleeping, to itch themselves. This often requires prescription medication to resolve the symptoms. Contact your local veterinarian for an appointment as soon as possible.

The most common causes of itching in cats

There are many different things that can cause your cat to itch. Click on the links to explore each cause in more detail.


Allergies are the most common cause of itching in cats and can be split into different categories

  • Flea allergy dermatitis: an infection of the skin caused by flea bites.
  • Food allergies: an allergy to something in the food. Usually the protein source, such as chicken or beef.
  • A contact allergic reaction: sudden in appearance and often seen as bumps all over the skin, usually starting around the face. Also known as urticaria, or hives.
  • Feline atopic skin syndrome: a type of skin allergy usually caused by environmental allergies such as pollen, dust mites, or smoke.


  • Fleas: are the most common cause of itching in cats. Indoor cats can get fleas too.
  • Mites: Demodex and Sarcoptes (mange), ear mites, harvest mites

Skin infections

These are often secondary to allergies or parasites.

  • Bacterial, yeast, or fungal
  • Ear disease: most often related to allergies. Can also be due to foreign bodies, ear mites, or masses in the ear.
  • Ringworm


  • Pain: often when it involves a specific area. Can cause cats to chew or bite at an area of skin. Includes acute pain, such as wounds, and long-term pain, such as arthritis.
  • Wounds or injuries: such as cat bite abscesses.
  • Stress: a common cause of overgrooming, often caused by a change in your cat’s environment or routine.

How to know if your cat is itchy

The medical term for itching is pruritus. It may not always be obvious that your cat is itchy. Some cats will secretly scratch or show other signs of being itchy, such as chewing, biting, rubbing, and licking.

You may notice skin lesions, such as:

  • Hair loss or bald patches, usually caused by overgrooming
  • Pink or red skin
  • Dark or thickened skin
  • Scabs, dry skin, a rash, hives, blisters, or black spots
  • Bleeding skin from self-trauma
  • Greasy skin, dandruff and flakes
  • Lumps and swellings

The eosinophilic reaction has three characteristic signs, including:

  • Swollen lip or chin
  • A plaque: red, thickened, painful and itchy area of skin that is common on the thighs, face and neck
  • A granuloma: a weepy and swollen area of skin that is common on the thigh, paws and in the mouth

  • Ear disease: itchy, red, discharge (including wax), smelly, swollen, shaking head
  • Eyes: itchy, weepy, red, holding them closed
  • Runny nose and Sneezing
  • Stress can cause both physical and behavioural symptoms, such as urinating abnormally, lethargy, a scruffy or matted coat, and weight loss.

Home treatment

How to treat an itchy cat at home

It’s always best to seek the advice of a vet if your cat shows signs of being itchy. Home remedies may be helpful for certain conditions, and your vet can guide you on the best ones to look for.

Allergies, in particular, can be tricky to treat, and it’s recommended to take a multi-modal approach. This means using different products and making changes at home to improve the signs.

  • Use a buster collar, inflatable collar, or medical pet suit to prevent further self-trauma.
  • Calming or medicated shampoos, mousses, wipes, or gels are useful for certain conditions, such as skin infections. These are often antibacterial and also soothe the skin.
  • Some ear cleaners can also help with mild irritations or infections.
  • Speak to a vet before using any of these home remedies, such as olive oil, apple cider vinegar, or coconut oil. These have limited research in cats and may be more harmful for certain conditions.
  • Make sure your cat is up to date with parasite control, especially fleas.


  • For mild itching, skin supplements containing omega oils can help protect the skin barrier.
  • A diet trial with a novel or hydrolysed protein is useful to check for food allergies. A novel protein is one that your cat has never eaten before. A strict trial should last 6-8 weeks before assessing the results; cut out all other food and treats.
  • Make sure all pets in the household are up to date on parasite control that covers at least fleas and mites.
  • If certain allergies are diagnosed: avoidance of these will help reduce the symptoms.


  • Calming supplements and pheromone adapters, along with advice from a vet.
  • Help from a certified behaviourist is often advised.

Anal Gland Disease




Vet treatment

Vet treatment for itchy cats

If the symptoms are severe, your cat will most likely need prescription medication from your local vet. Usually includes a full physical examination to assess the skin, ears, and all other body parts and determine if any further tests are needed.

Prescription medications include

  • Anti-itch medications: there are many different types of these, and your vet will work with you to find the best solution for your cat. Includes steroids and Atopica.
  • Immunotherapy: A medication made specifically for each patient based on the results of skin or blood tests for allergies. Helps to desensitise the body to different allergens. It works to reduce the severity of the symptoms of allergies and is usually given by injection every 2-4 weeks.
  • Anti-inflammatories: NSAIDs (non-steroidal anti-inflammatory medication). Often used to treat pain, wounds, and anal gland disease.
  • Antihistamines
  • Parasite treatments
  • Antibiotics: come in many different forms, such as shampoo, cream, tablets, liquid, or injection
  • Antifungals
  • Anxiety medication for cats with underlying behaviour concerns

Your cat may need tests to diagnose certain conditions:

  • Skin scrapes, hair plucks, or biopsy
  • Ear or anal gland flush and swab
  • Blood and urine tests
  • Intradermal skin testing if allergies are suspected
  • A strict food trial to check for allergies in the food
  • Imaging, including x-rays, usually done if pain is suspected



Are some cats more at risk of becoming itchy?


  • Rescue cats and those living in a multi-cat household can be more at risk of stress
  • Ear disease is often associated with an underlying allergy.


  • Can affect any cat but they are more common in those that spend time outdoors
