Why Do the Red Spots Appear on the Cat’s Ears?


Red spots on cat’s ears quite rightly alert pets’ owners, because often such manifestations indicate a serious disease. Especially when the cat starts shaking its head and scratching its ears, combing its skin to the blood.

How Do Ear Diseases Manifest?

It is not difficult to see that the cat is feeling discomfort, you just to take a closer look at the pet. If it constantly and anxiously shakes its head and attempts to get rid of the discomfort with his paws, it may indicate the development of a dangerous illness in the animal’s ears. In this case, by visual inspection, you will reveal not only hyperemia (redness), but also the accumulation of sulfur, crusts and fluid in the ears.

Normally, the color of the inner ear of a pet should be pale pink. The surface is usually a little shiny and glossy, but there is no moisture. Insignificant accumulations of sulfur are the norm. At that, its color can vary from light to dark brown. However, the main indicator is the smell. It should not be sharp and unpleasant.

Ear Mite

Otodectosis (or ear mite, ear scabies), is a disease that is most often caused by superficial sarcoptoid mites of Otodectes cynotis genus. These small-sized skin eaters parasitize in the upper layers of the epidermis. Scabies are diagnosed in 85% of pets, the auricle and the ear canals of which turn out to be annoyed. Symptoms of otodectosis include:

  • Severe itching, provoked by damage of the surface tissue structures by waste products secreted by parasites;
  • Swelling of tissues and redness due to thinning of blood vessels and their overflow with blood;
  • The appearance of black discharges (exudate);
  • The appearance of dark plaque in both ears;
  • Formation of dark brown scabs;
  • The occurrence of a plug in the ear canal after scabs accumulate too much. As a result, the pet begins to lose hearing;
  • Putrefactive odor;

If you find not only little red spot on cat’s ear, but also all or some of the above mentioned symptoms, you should immediately show the pet to a specialist. The fact that running otodectosis can lead to labyrinthitis (inflammation of the inner ear), and the last in its turn, to pathological disturbances in the brain, sepsis, and even death.

Infection of a healthy cat most often occurs after contact with the mite carrier. It may not necessarily be a direct impact. A cat can be also infected through carryings, combs, slickers or other items. Often mites are brought to the house by humans themselves. Uninvited “guest” can cling to clothes, hands and shoes especially in the warm season, when the temperature favors the life expectancy of the parasite. It is worth noting that young cats under the age of 1 year are most vulnerable to otodectosis.


When Eczema, a cat has red spot on ear as a result of ingress of water, chemicals or a foreign object into it. It may be also caused by:

  1. External stimuli (rubbing collar, contact with rough cloth, etc.));
  2. Allergic reaction of immune system to individually unbearable components (e.g., food);
  3. Fungi, bacteria, fleas and other parasites;
  4. Irritants (shampoos, dyes, household chemicals, etc.));
  5. Seborrhea (scruff);
  6. Chronic stress;
  7. Diseases of internal systems and organs (gastrointestinal tract, liver, kidneys, etc.).);
  8. Hormonal disturbance;

Eczema may be dry or weeping. The first form is characterized by the absence of infection in the affected areas. The surface epithelium is subjected to cornification, covered with dry scales and tuberosity. The second form is caused by fungi, viruses and bacteria of the pyogenic nature. When weeping eczema, blisters open on their own and tissue adjacent to the lesion, soften and continuously discharge exudate. Eczema flows into the chronic stage in 3-6 weeks after the beginning of its development. It is characterized by absolute dryness of the skin and atrophy of the hair follicles.

One of the forms of a bloody blister may occur in cats’ ears. It appears between the layers of the ear due to combing the ear. Blood from damaged vessels forms clots. They are usually removed by surgery, or by gentle treatment with special ointments. The course of their used on the affected area is a couple of weeks. Often, a hematoma is formed due to mechanical damage. If you practice free range with your pet, you should always be on the alert. The animal can seriously damage not only the ear, but also other organs, for example, in a fight with relatives or dogs, when falling from a great height, after being hit by the vehicle. However, sometimes a hematoma is formed because of existing diseases such as otitis, fungal infections of the ear, already mentioned otodektozis and others. Infectious and parasitic diseases cause cats desire to itch skin constantly, resulting in self-injury.

Other Reason

Other diseases that provoke redness in the ear are:

  • Dermatitis. It is similar to eczema in symptoms and causes, but does not have the nature of an allergic reaction. There is brown dirt in a cat’s ears, which can be easily removed with a cotton swab. The skin is slightly inflamed.
  • Otitis. Being an inflammatory process, this disease can hardly be diagnosed at home, as the cat on the contrary, will try to shake its head as little as possible. If you pay attention, you can hear the liquid  squelching in the cat’s ear. Otitis develops on the background of a weakened immune system.
  • Ringworm. It is caused by microscopic mold fungi – trichophyte or microsporum. In addition to the redness you will notice that your pet is balding by leaps and bounds. On the bald spots peeling appear, and possibly purulent wounds. If you notice even a small bald spot on a cat – it is better not to risk and immediately advise a vet. You could easily get rid of the ringworm if you start the treatment in time.

In order to prevent the appearance of redness and other negative symptoms, take enough time to care for the ears of the pet. Inspect and gently clean the external auditory passages of the pet, and do not allow water to enter its ears and nose.
