A cat has a black spot on its nose - 5 causes of dark spots

As much as you love your feline companions, it's easy to worry about any new thing on their faces, from crusty eyes to nasal discharge. Blackheads often appear on your cat's nose, and this can be a cause for concern. So, have you ever wondered what that black thing is on a cat's nose?

The black stuff on your cat's nose is caused by boogers, mucous nasal discharge from dust, or scabs. Small spots of dried blood are signs of a bacterial infection. Feline herpes or lentigo can also cause discoloration of the nose.

It's good that you're paying attention too: cats' tears and other things on their faces can be an indicator of their health. Sometimes this discharge tells you that your cat is healthy, and sometimes this discharge can be the first sign of a problem and a sign that it is time to see a veterinarian.

Nose injuries

The crusts on your cat's nose may be brownish or black. This symptom is characteristic of a fungal infection, an inflammatory process in the nasopharynx, or an allergic reaction. The most harmless cause of crust formation is considered to be household injuries.

The fact is that a healthy cat's nose is slightly moist. This prevents the normal restoration of damaged skin, so wounds can take a long time to heal. If the owner is absolutely sure of the nature of the crusts, it is necessary to help the pet’s body recover as quickly as possible. To do this, it is recommended to treat your nose with an antiseptic several times a day. Preventing re-infection of the wound significantly accelerates regeneration and the crusts begin to disappear a few days after the start of treatment.

A dark crust on the nose, which is accompanied by discomfort and is a consequence of skin damage, should not be a cause for concern. In this case, no treatment is required; the crust will fall off on its own when the tissues are completely restored.

Treatment with an antiseptic is only necessary if weeping erosions or crusts appear at the site of the wound, blocking the respiratory tract.

Allergic reactions

Another common cause of sores on the nose can be considered allergic reactions, regardless of their origin. You can guess the nature of the lesions by the presence of the following signs:

  • Sores of allergic etiology are almost always accompanied by the development of severe itching. At the same time, the animal constantly strives to scratch its nose with its paws, or by “wiping” furniture and other interior items.
  • Allergies are characterized by mild swelling and swelling of the affected tissues, which is caused by local migration of leukocytes to the site of penetration of allergens.

First aid is provided as follows:

  • You can give your cat ½ tablet of diphenhydramine. Submission frequency: up to two times a day, three days in a row.
  • The sores themselves are treated with the drugs already described above.
  • Until the root cause of the allergy is identified, it is better to change the food to a hypoallergenic one; we recommend feeding your pet from a glass or metal bowl (allergies to plastic can also occur).

Crusts on a cat's nose

The cause of sores and crusts on the nose in cats can be malignant neoplasms. Most often, this is squamous cell carcinoma that occurs on the skin and mucous membranes in the head area. The cause of the disease is excessive exposure to the sun. It is more common in areas with a warm climate and plenty of sunny days.

The risk group includes individuals who are white or have large white spots on their bodies. The likelihood of malignant degeneration increases as the animal ages and with increasing time spent outside the home during hours of active UV radiation (from 10-11 a.m. to 4-5 p.m.).

Symptoms of the disease:

  • long-term non-healing erosions on the skin;
  • dark red spots with a cauliflower-like surface;
  • crusty, concave ulcerations surrounded by an edematous ridge.

When cancerous lesions become infected with bacteria or fungi, a film or plaque with an unpleasant odor appears on them.

If the sore does not heal within 10-15 days, and progression of symptoms is observed (expansion of the affected area, enlargement of lymph nodes, deterioration in the pet’s general well-being), you should consult a veterinarian. In the absence of adequate therapy, squamous cell carcinoma gradually not only destroys the nasal cavity, but also spreads to neighboring areas. As a result, the animal may die.

The diagnosis of the disease is carried out by a specialist. He prescribes a biopsy of the affected area and blood tests. If necessary, an MRI is performed and an X-ray is taken. Timely diagnosed squamous cell carcinoma responds well to treatment: the affected areas are surgically removed. If the tumor is small, it is subjected to laser ablation.

Why do crusts appear?

Mechanical damage

A red or brown spot on a kitten's face is the result of injury. A healthy pet's nose is always slightly moist, as a result of which when a wound appears, it takes a long time to heal. If the owner is sure that the problem is related specifically to mechanical damage to the skin, then it is worth treating the affected area with antiseptics several times a day. In this way, it is possible to speed up the process of disappearance of the stain and prevent infection from entering the wound.

Veterinarians warn that antiseptic solutions are required if a weeping erosion or crust appears in the cat’s wound area, which prevents the pet from breathing normally.

Infectious diseases


A sign of an infectious disease may be the animal’s reluctance to eat any food.
If a cat's nose darkens or a light-colored stripe appears on it, this may be the result of an infection in the wound. Such a disorder can be recognized by the altered state of the pet. The kitten becomes lethargic and does not want to eat, including its favorite treats. In a severe form of an infectious disease, as a result of which a black spot appears on the nose, the following symptoms are observed:

  • gagging;
  • diarrhea;
  • dehydration of the body.

In case of such an illness, you should not delay going to the veterinarian, especially if the cat has not received all vaccinations. An infectious disease is fraught with serious complications. A black crust that forms near a kitten's nose can develop into a rotting wound and lead to other dangerous consequences that result in the death of the pet. It is impossible to cope with the problem at home on your own, since the animal requires long-term therapy in a hospital setting.

Skin diseases


Often behind this symptom lies a fungus that has infected the pet’s skin.
Some owners do not pay much attention to this problem, thinking that the cat simply has a dirty nose. But often the cause of the disorder is a dermatological disease of varying complexity. The source of the disease are fungi and bacteria that actively multiply. To select treatment, your pet must undergo laboratory tests to determine the causative agent of black spots in the nose area. Different groups of medications are prescribed to treat the crusts that appear. It is equally important to regularly wipe your cat’s nose with antiseptics to prevent re-infection.

Allergic reaction

Black spots on a cat’s nose or in the lip area can appear as an allergy to various irritants. In most cases, dry crust occurs due to the consumption of certain foods, as a result of which the kitten has an allergic reaction. But sometimes the problem is related to the contact of a pet with household chemicals. To eliminate stains in the nose area, you need to take antihistamines, which are purchased at a veterinary pharmacy as prescribed by a veterinarian.

Does calcivirosis affect?


With this disease, characteristic wounds can be found in the animal’s mouth.
A white spot or black nose in a cat sometimes appears against the background of a disease of infectious origin. The disease most often occurs in pets that have not been vaccinated. Calcivirosis is accompanied not only by a spot on the nose, but also by other symptoms:

  • wounds of various sizes in the mouth and ears;
  • inflammatory reaction of the conjunctival membrane;
  • increased tearing of the eyes;
  • damage to the joints of the cat’s limbs;
  • heat;
  • enlarged lymph nodes;
  • labored breathing.

Veterinarians note that if a cat has calcivirosis, it is necessary to use special drops that dissolve the crusts and allow the pet to breathe normally.

Calcivirosis

Calcivirosis is a dangerous viral disease of cats. In addition to the nose and oral cavity, the infection can affect the respiratory, hematopoietic and nervous systems of animals, and the digestive organs. The disease is often severe, with symptoms appearing within 1-3 weeks, and about a third of those affected die. Survivors are able to shed the virus into the environment for up to 12 months. With stress, deterioration of living conditions, infection with VLK or FIV, a relapse of calicivirus occurs. If a secondary infection occurs, the mortality rate increases to 80%.

To avoid death, you need to show the animal to a veterinarian as soon as possible.

What are blackheads in cats and why are they dangerous?

Blackheads (acne) are clogged sebaceous glands. The characteristic dark head occurs when sebum oxidizes. The appearance of such symptoms in an animal may indicate disturbances in the functioning of the body, the presence of parasites. Such a problem cannot be ignored.

Black spots can trigger the occurrence of furunculosis, which is characterized by a purulent process occurring in the inflamed sebaceous gland. This condition is dangerous for the pet’s health and can contribute to the spread of infection. Outdoor animals are most susceptible to acne, but comedones can also occur in indoor cats.

Blackheads in cats are caused by blocked sebaceous glands.

Malfunctions of the sebaceous glands also appear in completely healthy pets. If a cat likes to play outside, a small amount of dirt gets into the mouth and, mixing with sebum, clogs the duct. Most often, comedones are localized on the chin.

When acne occurs, the sebaceous gland becomes inflamed and expands. If the pore is not cleaned in time, bacteria will begin to multiply, which will cause the appearance of pus.

Pet treatment

If your cat's nose begins to turn black, you should not self-medicate or waste time. Without special education, it is impossible to establish the exact reason why the nose turned black or discharge began. And not only the pet’s health, but also its life often depends on a timely visit to the veterinarian. It is useful to always have in your phone the contacts of a good veterinary clinic that is open 24 hours a day. One day this could save a pet's life.

Only a veterinarian can correctly diagnose and prescribe treatment for a cat.

Important! It should be remembered that water is much more important than food. The animal will live no more than two days without water, so you need to carefully monitor the pet and, if necessary, forcefully water it from a syringe, after immobilizing its paws.

Diagnosis and treatment methods

The therapeutic course for spots on the nose is selected by the veterinarian based on the diagnostic results. The main thing in making a diagnosis is a laboratory test to determine the pathogenic microflora that caused the rash on the face. Blood and urine tests may be required. For black spots, local treatment is prescribed, but for advanced cases of the disease, an integrated approach is required using medications from different groups.


Among the antiseptics, Miramistin is suitable for animals.

When rashes on a cat’s nose are associated with an allergic reaction, drugs with antihistamines come to the rescue. For daily treatment, antiseptics are used, such as:

  • "Miramistin";
  • "Chlorhexidine."

When spots on a cat’s nose are caused by a dermatological disease, antibacterial agents that suppress the activity of pathogenic microorganisms are necessarily used for treatment. It is equally important to adjust your pet’s diet by eliminating fatty foods and adding more fresh food. Omega-3, 6 and vitamin supplements help strengthen the cat’s immune system and prevent the appearance of other spots. It is possible to use folk remedies, such as a decoction of chamomile or celandine, which is used to treat the cat’s nose.

Prevention of a runny nose

Several recommendations for the prevention of rhinitis in cats.

  • The best prevention of a runny nose in a cat is timely vaccination. Although, unfortunately, even this does not provide a 100% guarantee of health, but it increases the chances.
  • Do not allow the animal to become hypothermic. There should be no drafts in the house, and the pet’s bed should not be located in a cold place.
  • Monitor your cat's immunity. Feed correctly (balanced), do not forget about fortification. However, remember that excess vitamins also have a bad effect on the animal’s condition.
  • Eliminate possible allergens (hypoallergenic food, minimum chemicals when caring for animals, keep indoor plants away).

How to clean snot

Although this is a simple procedure, it is quite unpleasant for the cat. It is important to approach the matter seriously and pay attention to details: preparation, encouragement of the pet, and most importantly, proper restraint of the cat. This procedure is similar to washing a dog’s nose, and if you have already done it, then there will not be any particular difficulties.

It is better to ask someone to help hold your pet, but you can rinse the nose yourself. To begin with, prepare a place, the necessary tools and medicines, as well as treats for reward. You should strictly use only those medications prescribed by your veterinarian.

What you need to prepare in advance

  • a syringe with a volume of 1 - 2 ml (can be replaced with a small syringe, it is also very convenient for these purposes, but in this case it will be more difficult to dose the medicine);
  • a couple of towels (one for fixing, the second for covering);
  • cotton pads, napkins;
  • necessary medicine to rinse the nose with;
  • treats for encouragement.

It is better to rinse your pet’s nose in the bathroom over the sink so as not to drench the furniture and floor. However, many cats get nervous in such a place, so you can prepare a towel and carry out the manipulation on the table. It is important to provide good lighting to make it comfortable to work. 0.5 - 1 ml of liquid is drawn into the syringe (as indicated by the veterinarian) and the needle must be removed.

After preparation, they take the cat in their arms, be sure to talk to it affectionately and encourage it. If the pet is calm, you can hold it yourself. If the cat is very active or nervous, it is better to wrap it in a second towel and ask a friend for help.

How to wash

Holding the pet firmly by the withers and head, the cat is immobilized. It is important to watch the paws; be sure to secure them well. You can sit it on a table, or you can hold it on your lap, whichever is more convenient for the person doing the washing.

First you need to assess the condition of the nose - if there is dirt or crusts on the outside - they are removed with a moistened cotton pad or napkin. After the nose is as clean as possible, proceed to rinsing.

The pet's head is held in a horizontal position; you can tilt it slightly to the side for convenience, but you should not throw it back. With your right hand (for left-handed people, your left hand) take an already filled syringe without a needle and carefully insert its tip into the nostril. You need to insert the needle cone (the thin plastic nose of the syringe onto which a needle is placed, if necessary) very shallowly; it is only important that it fits tightly to the nostril and the liquid enters the nasal cavity and does not flow out through the lips.

Carefully and smoothly pressing the piston, inject the medicine into the pet's nose under gentle pressure. You cannot press the plunger sharply, so as not to “shoot” the medicine in the nose - this can only scare the cat and harm it. Also, do not press jerkily; it is important to calculate the force of pressure.

After introducing the liquid, the excess is wiped off the muzzle. The same is repeated from the second nostril.

Recommendations

Be sure to talk gently and calmly to the pet all the time, praise it exaggeratedly to make it clear that the owner is not causing harm, but is providing assistance.

Advice! If the cat does not give in, it is better to put the syringe aside and calm her down. After some time, when your pet is in a more relaxed state, you can try washing again. However, you should also not follow your pet’s lead. It is important to feel the line when a cat is really nervous and where it is cunning.

After the procedure, they are sure to give some goodies to praise and smooth out the unpleasant impression of the manipulation. If you associate nasal rinsing with a pleasant ending, the cat will soon understand the connection and the procedure will be easier next time.


The cat is clearly accustomed to the procedures, as he does not actively resist

How can you perform the procedure?

It is important to check the expiration date of the rinse and its temperature before use. Do not inject hot or cold solution into the nasal passages; you need to rinse it at room temperature or at body temperature.

Saline solution

Usually, to facilitate breathing, saline solution is used (0.9% aqueous solution of sodium chloride, which can be purchased at any pharmacy - human or veterinary). However, the veterinarian may prescribe other medications on an individual basis if necessary, and in addition to them, prescribe other medications in the form of tablets, drops or injections.

Chlorhexidine

We do not recommend rinsing your cat’s nose with chlorhexidine solution in any situation. The decision on its use and concentration of the solution can only be made by a veterinarian. This drug has quite a strong effect on the mucous membrane of the cat’s nasal cavity and if you do it ineptly, you will most likely harm your pet.

Other drugs

Under no circumstances should you self-prescribe medications to your pet, use human or inappropriate veterinary medications, or change the dosage. If it is indicated to instill or irrigate the nasal mucosa with medications, this is done after rinsing after a little time.

Usually the nose is washed 2-3 times a day, for 5-7 days, but in some situations, rinsing is prescribed more often, up to about 5-7 times a day. The duration of treatment is also selected individually depending on the situation and condition of the cat.

More serious reasons

There are several more serious reasons for a black spot on your cat's nose. Sometimes a bacterial infection can cause your cat's mucous membranes to change color, in which case your cat will likely need treatment for a respiratory infection.

In this case, the black color may be blood again, but this is usually due to irritation of the nose and respiratory tract and may be a sign that your cat is in trouble.

Another reason is feline herpes. Although it may seem incredible, the good news is that many cats are completely unaffected by herpes and cannot be infected with the herpes virus.

However, if one of your cats has herpes, chances are every other cat in your home also has the virus. It is important to prevent uninfected cats from coming into contact with infected ones, including keeping the cat indoors only after diagnosis.

Herpes does mean that you may have to wipe off the discharge, and your veterinarian may prescribe some cleaning products to keep the problem under control.

Of course, if you are unsure why your cat is having nasal discharge (of any color), especially if the discharge is sudden or more than usual, you should take your cat to the vet. Taking her to the vet is the best way to make sure your cat remains safe and healthy.

As a general rule, your cat's nose should be clean and dry. Some cats have wet noses, but this is not very common. If you notice changes in your cat's nose, it's best to get a physical exam just in case.

Causes of black spots on a cat's nose

There are many things that can happen to your cat that can cause a black spot to appear on its nose. Even small scraps of black fabric from one of their favorite toys may look like something you need to worry about until you take a closer look.

You should also take a close look at any black things on your cat's nose if you usually wear black clothes or have dark furniture or carpeting. Lint and dust from these dark sources can easily get into your cat's nasal lining and cause dark discharge.

This is the mucous membrane that does its job and protects your cat's respiratory system. But if it's a common occurrence, consider vacuuming or scrubbing away possible sources of lint, or even keeping your cat away from the source. This is because black nasal discharge can sometimes be more serious, and you don't want to miss signs of illness due to lint.

Another less dangerous cause of black spots on your cat's nose could be a small scratch on the surface of the nose and the scab has dried out. If you have multiple cats at home, it is not uncommon to find small scratches on your cat's face. Cats are territorial and will often use their claws to force another cat to retreat if hissing and fluffing their fur doesn't help.

Nose scratches are more common in cats when a new cat first arrives, but can occur at any time while two cats live together.

Your cat may also accidentally scratch its nose while playing alone, especially if your cat is allowed to go outside.

Your cat's nose is relatively sensitive, so they may find it a little uncomfortable if it is scratched. Luckily, the scratches are usually not that serious. Just keep an eye on them to make sure they keep the scratch clean and don't rub too hard. If your cat starts pawing at her face or her nose appears redder or swollen, it's time to see a veterinarian in case the scratch is infected.

When should an owner sound the alarm?

Black dots on the nose that have developed for pathological reasons, due to hormonal, systemic disruptions in the body, may be accompanied by the following symptoms:

  • itching, scratching on the face;
  • restless behavior;
  • the appearance of a skin rash, bald patches on the body;
  • poor coat quality;
  • dry nose;
  • unstable temperature;
  • decreased activity;
  • refusal of food;
  • increased thirst;
  • skin inflammation;
  • the appearance of scabs, dry crusts on the nose;
  • swelling.

If dark dots, spots of different diameters, increase in size, are distributed throughout the animal’s body, ulcers are noticeable, or other signs that are not typical for a healthy cat, it would be a good idea to show your pet to a veterinarian, since such symptoms may signal the development of neoplasia and skin cancer.

Malignant pigment spots have a dirty yellow, brown, dark brown color with a reddish tint, and uneven edges. They may protrude somewhat above the surface of the skin. In severe cases, blackheads can spread throughout the pet's entire body.

Dermatitis of various origins

Another reason is dermatitis, i.e. skin inflammation. There can be many reasons for their development (including those already mentioned above):

  • Multiple bites from fleas and other ectoparasites.
  • Action of caustic and irritating substances.
  • Frostbite and burns.

First aid is provided as follows:

  • The nasal skin is cleaned regularly, removing dirt and exudate with a cotton pad and sterile, warm saline.
  • In severe cases, it is recommended to put a surgical collar on the animal to prevent scratching of the sores.
  • In many cases, applying syntomycin liniment and 3% tetracycline ointment to the nose 3 times a day helps.

But! A white nose can be an alarming symptom!

If your cat's nose discolors from pink to white, it may be a sign of dehydration or anemia (decreased hemoglobin levels in the blood, usually with a decrease in the number of red blood cells). Anemia itself is not a disease, but it is considered one of the symptoms of various pathologies.

First of all, you should pay attention to your pet's gums. If, instead of a healthy pink color, they also have a pale appearance, this is a reason to urgently contact a veterinarian to rule out any serious problems or catch the disease as early as possible for successful treatment.

Anemia can be caused by an unbalanced diet and lack of microelements, or be a sign of leukemia, a viral disease, pathology of internal organs (for example, renal failure), etc.

If the whitening of the nose is accompanied by other symptoms (diarrhea, apathy, lethargy, loss of appetite and weight), medical intervention is required immediately!

How to Groom a Cat to Clean Its Nose

A cat's nose is a very sensitive part of their body, so it's normal not to let them touch it, especially if the manipulation lasts more than a second. If you readily accept contact, it is best to hug him to prevent him from escaping and keep your head more or less still. And all this without squeezing or overwhelming you too much.

In the case of cats that do not tolerate handling, one option is to wrap them in a towel to prevent them from scratching during an escape attempt or even to protect themselves. In addition, there are fabric traps on the market for more effective immobilization.

As with other animals, these situations should always be positive during training. The first time a cat is caught and its nose wiped, it can become very fearful and this can lead to psychological problems.
