Distemper in cats - transmission routes and incubation period, symptoms, diagnosis, treatment methods and disinfection

Distemper in cats has other official names, so you should not be misled by the question: “What is panleukopenia.” This is a very dangerous virus with a high probability of death, which is difficult to destroy. It can withstand low and high temperatures and, even in unfavorable environmental conditions, remains virulent for up to a year. Under no circumstances should you self-medicate or let the disease take its course. Only if you go to a veterinary clinic does your pet have a chance of survival.

What is distemper in cats

This is a highly contagious viral disease, which is also known as infectious parvovirus enteritis or panleukopenia. When infected, the number of all types of leukocytes in the bloodstream sharply decreases, the intestinal epithelium is affected, and a generalized infection affects the lymphatic system. Panleukopenia occurs more often in kittens - the still fragile body is more susceptible to the virus. The most dangerous time is spring and summer, when animals breed. Distemper in cats shows a high mortality rate, so it is important to start treatment in a timely manner - when the first signs appear.

Establishing diagnosis

Panleukopenia is a very dangerous disease, so the main thing to do when the first symptoms appear is to show the animal to a veterinarian. To make a diagnosis, attending physicians first examine and listen to four-legged patients, and then ask the owners about when the first symptoms of distemper appeared in cats.

After analyzing the data obtained, the animals are prescribed a set of studies.

Diagnostic methods

To understand whether a cat has the causative agent of panleukopenia in its body, blood and feces are taken from it for examination. To detect the virus, the following diagnostic methods are used:

• clinical blood test;
• examination of feces using the PCR method;
• blood chemistry;
• Ultrasound of the abdominal cavity;
• smear of discharge from the eye.

On a note. PCR testing may give a positive result in recently vaccinated animals. Therefore, be sure to check how long ago the cat was vaccinated.

Differential diagnoses

For effective treatment of distemper in cats, it is important to make a correct diagnosis. Since panleukopenia has symptoms characteristic of many diseases, the first step is to exclude:

• feline immunodeficiency virus;
• acute toxoplasmosis;
• intestinal perforation;
• pancreatitis;
• intoxication of the body;
• leukemia.

Panleukopenia virus in animals

Feline distemper occurs as a result of damage to the animal's body by parvovirus, the name of which in Latin is Virus panleukopenia feline (FPV). The virus retains its virulence in the external environment for up to one year, while it does not decompose when heated for an hour to 60°C, does not respond to changes in acidity ranging from pH 3.0 to 9.0, is not afraid of frost, and can withstand the effects of pepsin and trypsin , diethyl ether and chloroform - thanks to such amazing resistance, the pathogen can easily infect more and more victims.

How is it transmitted?

The sources of this deadly disease are sick cats and virus carriers. Parvovirus is shed in stool (feces, urine) or saliva. There are several ways of contracting panleukopenia:

• During oral contact. The virus can enter the oral cavity along with saliva. More often this happens when drinking water or eating food infected with viral particles from a virus carrier or a sick animal.
• By airborne droplets. A healthy individual becomes ill with panleukopenia while in close proximity to a patient.
• By contact method. Infection occurs through personal belongings, clothing or shoes of the owner of a furry animal who has been in contact with a virus-carrying cat. In addition, parvovirus survives on litter trays, harnesses, bowls and toys for up to a year.
• In utero. The virus easily passes through the placental barrier and penetrates the fetus. Kittens infected at an early stage of pregnancy die (decompose inside, mummify) before birth or die 1-2 days after birth. Babies infected at a late stage often have congenital underdevelopment of the cerebellum.
• Transmissible method - when the causative agent of panleukopenia is carried by blood-sucking parasites - ticks, fleas, bedbugs.

Almost all representatives of the cat family can become infected with parvovirus: tigers, leopards, cheetahs. Among domestic animals, distemper is a widespread disease, to which unvaccinated kittens under one year of age and cats older than 6-8 years are more susceptible: young animals are predisposed to the disease due to undeveloped immunity, and older pets with age lose the ability to resist various viruses, because the immune properties of the body become weaker.

Pregnant cats and small kittens are also at risk of contracting panleukopenia. The chances of contracting plague increase in babies over two weeks of age. This is explained by the fact that the mother’s immunity weakens, and the baby’s own immune system is not enough to resist such a dangerous virus. If we consider breed predisposition, parvovirus is most dangerous for British representatives, Maine Coons, Siamese and Persian cats.

Is it dangerous for humans?

Panleukopenia is not dangerous to humans. They can only act as carriers of parvovirus on their outerwear, shoes and other things. Owners of several pets should be careful: if one cat has become infected with infectious enteritis, it must be isolated from a healthy cat and strictly quarantined. It is noteworthy that dogs are not afraid of the virus. Although they can get distemper, it can be caused by a completely different type of parvovirus.

Why do cats get distemper?

The methods of infection are varied, because due to its high survival rate and resistance to exposure, the virus is very widespread. In addition to frost and heat, it can withstand treatment with disinfectants such as chloroform, ether, pepsin and trypsin.

Routes and methods of infection

The virus is shed from a sick animal in its feces and saliva. It can be transmitted to a healthy cat in different ways.

:

1. Oral route

   infection is possible when the virus is transmitted through particles of saliva of an infected individual that get into the water or food. If a healthy animal eats them, there is a high probability of infection.

2. Airborne path

   promotes infection when sick and healthy individuals are in the same space.

3. TOcontact method

   does not even require the presence of a sick animal - the virus is transmitted through the clothes and shoes of its owner, and is stored on bowls, toys, and litter trays. Therefore, you should not take a new kitten into your home if the previous pet recently died from this scourge.

4. Intrauterine transmission

   occurs from an infected mother to her young during pregnancy. They die before birth or within a few days after.

5. Transmission method

   involves blood-sucking parasites that are carriers of a deadly virus.

If you have several tailed pets, then at the slightest suspicion of panleukopenia in one, all the others should be urgently isolated, or better yet, resettled until the circumstances are clarified.

Risk group

The entire cat family is susceptible to this disease, from domestic cats to wild servals, cheetahs and lions. Plague in domestic cats is more common among breeding animals whose immunity has been damaged during long-term selection, especially among representatives of these breeds:

• British;
• Maine Coon;
• Persian

Adult healthy animals rarely become infected. For the most part, the disease threatens

:

• unvaccinated babies older than two to three weeks, who are no longer affected by the mother’s immunity, transmitted through milk, and their own has not yet been formed;
• young animals up to one year old;
• elderly individuals with weakened immune systems;
• pregnant women, especially street women;
• sick cats and allergy sufferers.

Of course, the main risk group is unvaccinated pets. Even an elderly vaccinated cat will cope with the disease better than a healthy and young, but not vaccinated animal.

Forms of the disease

Distemper in cats develops subacutely, acutely or superacutely (with lightning speed). Find out more about these forms of the disease:

• Subacute form – typical for cats with strong immunity. The incubation period can last up to several weeks. Clinical signs of plague in the subacute form are not clearly expressed. Full recovery is possible provided that the animal's immune system is at a high level.
• Acute - in this case the incubation period is 1–2 days. Panleukopenia in this form mainly affects adult animals.
• The fulminant form of the disease is typical for young furry pets. Distemper in a kitten develops rapidly - literally within a few hours after the pathogen enters the body. The hyperacute form of the disease is clinically similar to the symptoms of rabies, while the signs often do not even have time to develop, and the animal dies in a very short time.

What can panleukopenia be confused with?

Firstly, with poisoning. An important difference between panleukopenia and poisoning is that with this disease, at the initial stage of the disease, the animal’s body temperature rises significantly, up to 40-41 degrees and above. In case of poisoning, the temperature is normal or low. However, kittens quickly enter the second phase of the disease - exhaustion of the body, during which the temperature drops. In this case, only a veterinarian can distinguish between these two conditions.

Secondly, with acute toxoplasmosis. Most often, this infection is carried by cats asymptomatically, but in kittens it is difficult to distinguish between these two infections by symptoms. This is where express analysis or PCR comes to the rescue. Toxoplasmosis in kittens, although severe, is less dangerous than panleukopenia. There is a specific treatment for this disease, that is, drugs that kill the pathogen.

Thirdly, with pancreatitis, acute gastroenteritis of non-viral nature and other diseases of the gastrointestinal tract. With these diseases, the temperature may rise, but the pathogen will not be identified, and in small kittens they are all quite rare.

First signs

The virus manifests itself within 2–8 days from the onset of the disease. If the course of the disease is acute, the symptoms are:

• sudden refusal of food;
• oppression;
• increased body temperature, which rises to 40°C and above in 1-2 days;
• the cat behaves as if it is constantly thirsty, but at the same time drinks little;
• vomiting with dark yellow-green mucus appears;
• urine turns from dark yellow to light orange;
• the oral mucosa dries out;
• the blood vessels of the soft palate turn blue;
• During the examination, rhinitis, conjunctivitis, and swelling of the lining of the larynx are noted.

What can you do?

Distemper is not a case where self-medication is possible. The owner’s task is to take the animal to the veterinary clinic as quickly as possible, providing it with the most comfortable conditions. Call the nearest clinic and notify the doctors that you are traveling, then call a car, put the animal in a carrier, put absorbent diapers on the bottom in case of diarrhea and vomiting, and take several diapers with you.

It happens that there are no 24-hour veterinary clinics in a locality, and the symptoms of the disease begin to appear in the evening or at night. In this case, some owners resort to the folk method - vodka. Using a small syringe without a needle, pour a mixture of 1 teaspoon of vodka and 1 chicken yolk into the cat’s mouth. At the same time, they make sure that he swallows it and does not throw it up (which is quite problematic).

Ruslan: “My pet had distemper. We somehow immediately understood this, but at that time veterinary hospitals were only state-owned and did not work at night. In order for the pet to survive until the morning, we gave him regular vodka, after which he became happier and was even able to get up on his feet. In the morning I took him to the vet, who confirmed distemper. We were prescribed treatment, we received injections and were given medications that the veterinarian recommended. The animal has returned to normal.”

Veterinarians do not welcome this method and say that it can only be treated with medications, and the animals that survived this method survived in spite of the vodka, and not because of it.

Symptoms

Parvovirus first affects the small intestine, then the bone marrow, the lymphatic system, and then occupies almost the entire body. Each form of the disease is characterized by certain symptoms. Fulminant is a course of panleukopenia that can infect kittens up to 2 weeks of age. This form of distemper leads to a sharp deterioration in health, manifested in refusal to suck milk, plaintive squeaking, and apathy.

Even if timely treatment is started, the baby will most likely die within 2 days. There are other symptoms of feline distemper, which occurs in a hyperacute form:

1. lethargy;
2. lack of response to his mother;
3. matted, disheveled, unkempt, dull fur;
4. reluctance to move, paralysis;
5. trembling of limbs, convulsions;
6. lack of appetite, thirst;
7. vomiting blood or yellow or green foam.

In kittens aged 3 to 7 months, the nervous system suffers during the fulminant course of the disease. At the same time, to the above signs are added symptoms very similar to those that occur with rabies: the cat is frightened by any extraneous sounds, hides in distant secret corners, he begins to fear light, sunlight, he squeaks heart-rendingly when frightened, and nervous overexcitation is observed. After some time, loose stools, which have a specific foul odor, are added to the symptoms. In some cases, blood appears in the excrement.

The acute form of the disease occurs in adults. The symptoms differ from those characteristic of the fulminant form of plague and are as follows:

1. interest in everything that is happening disappears, the cat constantly lies, does not react to the actions and voice of the owner;
2. the temperature rises sharply to 41°C;
3. heavy breathing appears;
4. the animal refuses any food, even the most beloved;
5. vomiting begins with yellow or green foam, in which after 36–48 hours particles of blood and mucus appear;
6. rumbling in the stomach, watery diarrhea appears;
7. red spots appear on the skin, which first fester and then disappear.

The high temperature does not last long, then drops to 37°C. Lower rates are harbingers of imminent death of the animal. A sick cat is very thirsty, but due to spasms of the larynx and pain in the abdominal cavity, she cannot. When the parvovirus reaches the cat's heart, it begins to breathe with its mouth open, and heart failure and tachycardia develop. When plague affects the respiratory organs (lungs, bronchi), the following symptoms are added:

1. copious nasal discharge;
2. redness of the eyes, watery eyes;
3. hot, dry nose;
4. wheezing in the chest when breathing, cough;
5. frequent coughing;
6. foci of inflammation on the epidermis filled with pus.

The subacute form is the most favorable form of the disease, in which almost all the main markers of plague can be traced, but their manifestations are insignificant. In this form, the disease occurs mainly in animals with stable immunity, in vaccinated animals and in individuals who are naturally in good health.

Infection

Distemper is a dangerous disease that often leads to the death of a cat. It is caused by a viral organism called Feline Panleukopenia. This organism has high vitality, it is resistant to strong heating and freezing. It is also impossible to destroy it with modern disinfectants, and in an open environment it can exist for a year.

Note! The viral causative agent of distemper in cats is usually found in conditions associated with sick or recently ill animals. These include saliva, feces, and nasal discharge.

The routes of infection with distemper in cats can be as follows:

• a pet can become infected with a dangerous viral disease by communicating with infected cats or by coming into contact with its saliva, feces, or nasal secretions;
• infection can occur through airborne droplets. A cat can become infected with distemper through the air, but only if it is near an infected animal;
• kittens can become infected from their mother during intrauterine development;
• The viral organism can be transmitted by blood-sucking insects that parasitize infected animals. These include ticks, fleas, lice;
• A pet can become infected through a person. In this case, infection occurs through the owner’s clothing or shoes, for example, if he brought a viral pathogen on it from the street. Cats that are constantly at home and do not go outside can become infected in this way.

But still, many are interested in the question, does plague pose a danger to humans? This question can be answered in the negative. This is an animal disease and has nothing to do with humans.

Diagnostics

Only a veterinarian can determine whether an animal has distemper. To do this, at the slightest suspicion of infection, the cat must be taken to the clinic, taking with you a passport containing vaccination information. The doctor makes the diagnosis based on medical history, examination, laboratory and clinical tests. First of all, the veterinarian checks the stool for the presence of parvovirus particles - this test is performed using the polymerase chain reaction (PCR method). It should be noted that the PRC method will show a positive result only if the cat was vaccinated shortly before infection.

A characteristic sign of infection with panleukopenia is a sharp decrease in white blood cells. For this reason, a blood test is prescribed for a sick pet. The veterinarian carries out a differential diagnosis, because the signs of distemper in a cat are similar to the symptoms of pathologies such as poisoning, feline immunodeficiency, leukemia, pancreatitis or intestinal perforation.

What should a cat owner pay attention to if their pet is ill?

Having found out whether cats suffer from distemper, what it is called correctly and why it is dangerous, you should remember its sympathetic signs in order to make it easier for the doctor to make a diagnosis and not become the cause of the death of your furry pet.

The incubation (latent) period from the appearance of the virus in the body to the first manifestation of symptoms of infection ranges from 2 to 12 days.

The disease manifests itself acutely:

• the kitten suddenly refuses any food;
• the temperature rises sharply;
• vomiting of a greenish-yellow mucous mass opens, sometimes with blood;
• urine changes color from dark yellow to orange;
• the mucous membranes of the mouth become dry and cyanotic colored;
• eyelids swell due to conjunctivitis;
• Rhinitis begins - liquid discharge from the nose.

Sometimes there is a hyperacute manifestation of panleukopenia, which ends in the death of the young animal in just a few hours.

In the hyperacute form, any own efforts and efforts of doctors are powerless - accept this fact.

Don’t rush to take a kitten with similar symptoms to the clinic! – The panleukopenia virus spreads in a hurricane, and it’s easy to infect weakened animals waiting in line for the doctor’s help.

You're in trouble, but you shouldn't add stress to other pet owners because of it.

Arrange with the veterinarian for a specific time for the visit or invite him to your place.

For the health of the owner, the disease of his pet with panleukopenia is completely safe, which cannot be said about other felines living in this house or in the neighborhood.

Treatment of distemper in cats

This disease is treated comprehensively, and this should only be done by a veterinarian. Therapy is of two types - etiotropic and symptomatic. Etiotropic – aimed at destroying the virus. The treatment uses the drug Vitafel, an immunoglobulin that fights the viruses of rhinotracheitis, panleukopenia and calicivirosis. Enterostat also helps to overcome the disease: the dose is 20 mg/kg 1 time/day for 7 days.

Excellent results can be seen after using the antiviral drug Fosprenil: the medicine is administered intramuscularly in doses of 0.5 ml for cats weighing 1–5 kg and 0.2 ml for cats less than 1 kg. The number of injections is affected by the duration of treatment:

• on days 1–2 – 4 injections/day.
• on days 3–10 – 3 injections/day;
• on days 11-13 – 2 injections/day;
• on days 14-15 – 1 injection/day.

Symptomatic therapy is aimed at minimizing the symptoms of distemper in cats. With this treatment, you need to take into account the following recommendations:

1. First, correct the acid-base and water-electrolyte balance of the body, i.e. reduce dehydration and neutralize intoxication. To do this, you need to inject a solution of sodium chloride intravenously or subcutaneously.
2. In the absence of vomiting, you can use Ringer's solution or Regidron orally. Each of these medications must be mixed with 5% glucose and a quarter teaspoon of soda. The daily volume of such a drink for a cat is calculated using the formula: 50 ml per 1 kg.
3. Increase urine output in order to rid the body of toxic products. In this case, it is advisable to use herbal preparations: lingonberry, horsetail, bearberry, etc.
4. It is mandatory to carry out antibiotic therapy to destroy the secondary bacterial microflora - the use of broad-spectrum drugs is indicated.
5. Use vitamin supplements in combination with iron-containing supplements. Such medications must contain folic, ascorbic acid, vitamins A, B, C. Iron-containing ones are, for example, Ferrodextran (1–2 ml for an adult animal) and Ursoferran (0.3 ml/animal).
6. It is necessary to stimulate the body as a whole and improve metabolism. Catozal is perfect for these purposes - the drug is administered daily for a week in the dosage specified in the instructions.
7. Use antispasmodic medications to relieve spasms and reduce intestinal pain. Dibazol, No-shpa, etc. are suitable.

Diet

Distemper in cats is a serious disease, so after the animal is cured, it is important for the owner to take care of the appropriate nutrition for his pet. To do this you need to follow some recommendations:

• After the cat's appetite returns, the cat's menu should consist exclusively of light, slightly warm, pureed food.
• It is not recommended to feed your pet against his will - when he gets better, he will start eating on his own.
• Portions should be small, food should be given 5-6 times a day.
• It is allowed to feed low-fat broth, cottage cheese, kefir, and yogurt. After 3 days, you can gradually introduce a little boiled lean beef and fish fillet into the diet.
• Vegetables, fruits, grains, and any raw food are prohibited foods for cats that have just suffered from distemper - such foods can be given no earlier than after 2 months.

What can a veterinarian do?

The final diagnosis can only be made by a veterinarian. He will take blood for analysis, which in case of plague should show an increase in the number of leukocytes and other changes. The virus itself can also be isolated in a laboratory, but this takes more time, so usually a working diagnosis is made based on a combination of symptoms. Treatment is also prescribed symptomatically.

After the veterinarian has made a diagnosis and prescribed a course of therapy, most likely, the pet will need to be treated on an outpatient basis, that is, at home. On your part, strict adherence to the veterinarian's instructions and regular measurements of the condition are required: if it gets worse, call the doctor.

You cannot force a cat to eat: as soon as he gets better, he will start doing it himself. In the meantime, he is unable to, an IV will help.

All day long, the pet should be in a warm, dark, draft-free room. But you will have to ventilate it regularly; during this time, the cat must be taken to another place. It will be necessary to disinfect the room with special solutions, for example, sodium hypochlorite, as well as an ultraviolet or quartz lamp.

All feces and vomit must be removed immediately, and the area underneath must be disinfected: the discharge contains a huge amount of the virus.

If there are other animals in the house, they must be isolated from the patient for the entire duration of the illness.

Disinfection

As already mentioned, plague is a very dangerous disease that is resistant to many external influences. To keep your recovering pet and other cats as safe as possible, you must follow the recommendations for disinfecting premises:

• Treat the room where the parvovirus-infected cat is located using a UV lamp and javel water (sodium hypochlorite solution).
• To disinfect rooms, cat beds, toys, bowls, use soda ash mixed in water (1 part soda/20 parts water) and formaldehyde gas.
• It is imperative to wet clean (up to several times a day) the room where a cat suffering from distemper lies.
• Do not forget about regular ventilation of the room in which parvovirus hovers. During this time, the pet must be moved to another room.
• Create a comfortable air temperature.
• Quickly remove feces and vomit from the animal.
• It is important to ensure that direct sunlight does not fall on a cat suffering from distemper.
• Constantly rinse your eyes from pus accumulating in the corners by soaking a cotton swab in the medicinal liquid.

Home care

Proper care at home for a cat with distemper increases the likelihood of a successful recovery. If possible, it is better to give injections by calling a doctor at home, since any stress can negatively affect the animal’s condition. If you have to visit the clinic every day, then for transportation it is better to build a basket yourself (for example, from a cardboard box), so that you can burn it later.

The room where the cat is located should be warm and dry, without draft wind. Since the virus also affects the nervous system, you need to provide your pet with peace and shade with bright light.

You can drink both plain water (boiled) and decoctions of medicinal herbs. Their choice should be previously agreed with your veterinarian, because some medications and plant extracts may be incompatible. You need to feed your pet little by little, at the beginning of treatment - only broths, gradually adding porridge and chopped meat to them. It is recommended to follow a diet until complete recovery.

In agreement with the doctor, it is allowed to give the cat enemas. They may include herbal preparations, decoctions, and antiseptics. The tray and bowls should be placed next to the animal, and the bedding should be changed daily. Washing your pet while sick is not recommended.

Consequences

If you contact a veterinarian in a timely manner and provide assistance to a sick animal, the cat quickly recovers from distemper: the number of leukocytes in the blood is restored, it quickly gains weight, signs of rhinitis and conjunctivitis disappear, and body temperature drops to normal. After some time, the pet returns to its normal life.

It often happens that panleukopenia in cats does not go away without a trace. In this case, the furry pet will have unpleasant consequences for life. These include chronic disorders of the cardiovascular and respiratory systems, and nervous phenomena. After successful treatment, some animals are given special care and dietary ration for the rest of their lives.

Risk factors

The main mechanism of infection transmission is fecal-oral. The pathogen enters the environment along with the feces and vomit of a sick animal.

Panleukopenia in cats occurs upon contact with infected or recovered individuals, their waste products, household items they used (toys, dishes, scratching posts, beds, etc.).

A pet can become infected while walking or visiting a veterinary hospital. The virus can also penetrate home along with a person’s shoes.

Fleas can be carriers of parvovirus infection in cats. Carnivorous parasites transmit the pathogen to the animal during a bite.

Helminths in cats increase the risk of distemper, which often causes a weakening of the body's defense reactions.

Some veterinarians do not rule out intrauterine infection.

Another version of the mechanism of transmission of the panleukopenia virus is airborne.

The risk group primarily includes kittens aged 3-4 months, when immunity is just developing.

Prevention

Owners of furry pets should definitely know what methods exist to prevent such a terrible disease as distemper. To do this you need to know a few rules:

1. If there are several cats in the house, the uninfected animal should be given to friends or placed in a nursery during the treatment of the sick one.
2. If after three weeks of the incubation period the disease has not manifested itself in other pets, they must be vaccinated.
3. It is advisable to vaccinate a cat at an early age - when the kitten is 2 months old, after which it needs to be revaccinated after 3 weeks.
4. Adult cats from one year of age must be vaccinated annually, and pregnancy is a contraindication to vaccination.

Today there are vaccines that stimulate the production of intense immunity in animals, which lasts for a year. It is important to remember that only an absolutely healthy cat that has been treated for external parasites and helminths can be vaccinated. Vaccination is recommended with the following drugs:

• Quadricate;
• Multifel;
• Nobivac;
• Felocel.

Is canine plague dangerous for humans and other animals?

Do not confuse feline and canine distemper - despite the same names, the pathogen is different, so a cat cannot become infected from a dog and vice versa. The virus is not dangerous for people and other animals. But if a sick cat has had contact with other cats, then, in addition to isolation, all contacts need to be given anti-panleukopenia serum or globulin.

If they have not been vaccinated, then 21 days after the administration of the serum, the animals must be vaccinated if symptoms of the disease do not appear. A cat that has recovered from the disease becomes a carrier, and it is not recommended to take other animals for at least a year. The same applies to the situation when the pet died - the new animal will be in danger.
