How to Treat Feline Panleukopenia (Distemper)

Identifying the Signs of Feline Distemper

Keep an eye out for a high fever. The incubation period from being in contact with the virus to developing clinical signs is approximately four to five days. The first symptom to develop is a high fever, which can occur so suddenly that the owner suspects their cat has been poisoned. In adult cats that have a strong immune system or are vaccinated, they may contact the virus but keep it in check and not become ill.

Watch for vomiting and bloody diarrhea to start. This is the most obvious sign that your cat may have distemper. The diarrhea and vomiting is serious because it indicates distemper but it can also quickly lead to dehydration and anemia, serious problems on their own. If your cat vomits on a regular basis, for example due to hairballs, you will have to judge whether the vomiting your cat is doing is out of character or just its normal behavior.

Be on the look out for behavioral signs of distress as well. This illness will impact a cat's behavior, as it is likely to make them feel extremely ill. If your cat is extremely miserable and depressed and loses all interest in food, then you should suspect a serious illness, such as distemper.

Pay attention to the signs of secondary infections. The debilitated cat is at great risk of secondary infections such as pneumonia. A combination of blood loss, dehydration, organ failure, and secondary infections account for the high mortality rate.

Be especially vigilant about looking for symptoms in those most vulnerable. Those most at risk are the very young, with immature or weak immune systems. Typically a three to five month old kitten that has not been vaccinated is most likely to succumb to serious infection. It is estimated that around 50 - 90 % of the cats that come into contact with the virus die as a result.

Treating Feline Distemper

Take your cat to a veterinarian immediately. The vet should be suspicious of feline distemper based on the symptoms you have witnessed. Reaching a precise diagnosis is not essential since there is no 'cure' for panleukopenia, as it's caused by a virus. It is up to the cat's own immune system to fight the virus, and treatment is based around supporting the cat until the immune system mounts a defense. However, the vet may want to run tests to rule out other causes of a high fever (such as FIP or bacterial infections) and check for a foreign body or other causes of bowel obstruction, such as an intussusception, which is a problem with the intestine that can cause sickness and diarrhea.

Approve emergency treatment. If your cat is very sick, the vet may need to give it treatment very quickly in order to save its life. This treatment could include: Intravenous fluids: Aggressive intravenous fluids can help counteract dehydration. Given the extreme nature of the sickness and diarrhea, the cat may also become depleted in vital electrolytes, minerals, and glucose in the blood stream so these are added to the drip fluid as necessary, in order to normalize levels. Plasma or blood transfusions: With severe cases, the cat can lose a dangerous amount of blood and become profoundly anemic and also protein depleted. Finding blood for blood transfusions in the cat can be difficult but where the clinic has the resources to source a blood donor and match blood types, a blood transfusion can be life saving.

Discuss treatment with antibiotics with the veterinarian. There are a variety of treatments that may be given to your cat. These are based around supportive care, which works to support your cat's immune system while it fights off the infection. For example, all distemper is a viral infection, but antibiotics are often given because the cat is so debilitated it is vulnerable to life-threatening bacterial infections. Antibiotics are usually given by injection as the gut is compromised by the sickness and diarrhea.

Give your cat antiemetics. This type of medication will make your cat more comfortable. They are given to help the cat feel less nauseous and reduce the amount of vomiting. Antiemetics are anti-nausea medications, which include metoclopramide or maropitant.

Allow the vet to give your cat B vitamins. Intravenous B vitamins helps promote good bowel health and can aid recovery. Like the other treatments for distemper, they support your cat's immune system in its fight against the infection.

Consider experimental treatments. For example, cats with distemper may be helped by Interferon. Although it is not licensed for use in cats for this purpose, Virbagen Omega interferon may have a place in the treatment of feline distemper. It is licensed for this use in dogs and helps to strengthen the immune system to fight the infection.

Caring for an Infected Cat

Give your cat after care at home. Nursing care is essential, such as keeping the cat warm on a heat pad, since extremely poorly animals are prone to losing heat and hypothermia. Make sure your cat is as comfortable as possible while it works on recovering. The cat should be turned regularly, such as every half hour, and the side it is lying on changed. This reduces the risk of blood pooling on one side of the body, which can induce a form of pneumonia.

Feed your cat a special diet during recovery. If the cat survives the acute phase of the illness, it should be reintroduced to bland food, such as a prescription diet designed for gastroenteritis (Hills ID or Purina EN) or white meat and rice. This is fed little and often until the cat has been producing a formed stool for 3 - 4 days, at which point a slow transition back onto regular food can start.

Prepare yourself for the worst case scenario. A very high percentage of cats who are infected with distemper, especially kittens, die. This is a very serious infection that requires a very strong immune system to eliminate. It is your job to care for the cat as best you can. This means making it as comfortable and pain free as possible.

Preventing Panleukopenia Infection

Get your cat vaccinated. Highly effective vaccines are available that prevent panleukopenia infection. This is the most effective way to prevent your cat from getting this infection. The vaccine can be given from six to eight weeks of age and requires two doses, three to four weeks apart. Thereafter, the cat requires a booster after twelve months, and then vaccination every third year to extend the protection.

Keep very young kittens isolated. Young kittens do not start their distemper vaccinations until they are around six to eight weeks old. They are born with some antibodies received from their mothers, but this is not a sure bet for keeping the distemper virus at bay. In fact, these natural antibodies can counteract this vaccination, allowing those kittens with early vaccinations to be susceptible to the disease. This is why it is important to keep small kittens away from other cats. It is best to keep kittens away from other cats, expect for their litter mates and their mother.

Clean up cat waste in your yard. While it is not always evident that a cat has gone to the bathroom in your yard, if you see it you should clean it up. Many cats are outside cats and contact with other cat's feces can pose a health risk. Because the virus can be spread easily, it's also important to wash your hands before handling young kittens. This is especially important if you have been petting other cats recently.

Keep an infected cat isolated. Virus particles are excreted in infected feces, where they contaminate the environment and can remain infectious for years. Unfortunately, an added complication is that recovered cats can carry on excreting virus for six weeks after their recovery, providing yet more sources of infection for other cats. Because of this, it's important to keep a recovering cat isolated from other cats, so that it does not infect them. If you have multiple cats in your house it is most likely that they are all infected if one is infected. However, it's important to isolate the infected cat completely if by chance your other cats are not infected.
