Have you ever wondered if the dreaded cat disease FIP is contagious? Concerns about the health of our beloved four-legged friends are great, especially when it comes to such a serious disease as FIP.

FIP is caused by a mutation of the feline coronavirus and can spread among cats through feces, saliva or contaminated objects.

In this article, you will learn everything about the risks of infection, symptoms, diagnostic methods and treatment options for FIP, as well as how you can protect your cat from this disease.

Feline infectious peritonitis, or FIP for short, is a serious threat to cats caused by a mutation of the feline coronavirus. But how exactly does this virus become infected? It is important to understand that not every cat that comes into contact with the feline coronavirus also develops FIP. The virus is transmitted mainly through direct contact with infected excretions such as feces, but also through saliva and nasal secretions. The risk of transmission is particularly high in multi-cat households, animal shelters or breeding facilities.

Several factors can increase the risk of developing FIP in an infected cat. These include:

  • The age of the cat : Young and old cats are particularly susceptible.
  • The immune status : Cats with a weakened immune system, whether due to stress, other diseases or genetic predisposition, are at greater risk.
  • The environment : Living in close proximity to many cats promotes the spread of the virus.

Understanding which factors increase the risk can help to take preventive measures and minimize the risk of infection.

The Role of Coronaviruses in FIP

The feline coronavirus itself is harmless for most cats and only causes mild digestive problems. The real danger comes from a mutation of this virus that causes feline infectious peritonitis (FIP). This mutation is relatively rare, but when it occurs, it can lead to a serious and often fatal disease. Feline coronaviruses are mainly transmitted via feces, saliva or nasal secretions from infected cats. Young kittens in particular can become infected through close contact with their mother. Contaminated objects also pose a risk, as the virus can survive outside of a host body for up to seven weeks.

Recognizing Symptoms of FIP in Cats

FIP in cats may initially present with general symptoms such as fever, loss of appetite and weight loss , which can easily be confused with other diseases. It is important to pay attention to these early signs, as early detection can be crucial to the cat's treatment and well-being. As the disease progresses, more specific symptoms may appear that indicate FIP infection.

The symptoms of FIP vary depending on whether it is the wet or dry form of the disease. The wet form may cause an increase in abdominal girth due to fluid accumulation, while the dry form is often characterized by inflammation in various organs. Other symptoms include:

  • jaundice.
  • Difficulty breathing.
  • eye infections.
  • neurological abnormalities such as depression or seizures.

It is crucial to act quickly and consult a veterinarian if FIP is suspected.

Diagnosis of FIP: Methods and Procedures

Diagnosing FIP in cats is complex and requires a combination of tests. Since no single test provides a definitive diagnosis, veterinarians must rely on a mix of clinical signs, blood tests and imaging. The most important tests include blood analysis, which can indicate abnormalities such as anemia or elevated bilirubin levels, as well as more specific tests such as the detection of antibodies to the coronavirus. However, positive detection of antibodies does not equate to FIP, as many cats carry the virus without ever developing symptoms.

In some cases, a more precise diagnosis may be necessary by taking and examining body fluids or tissue samples. This involves methods such as diagnostic laparotomy or PCR (polymerase chain reaction), which can detect the genetic material of the virus. In the wet form of FIP in particular, an analysis of the abdominal fluid can provide crucial clues. It is important to understand that despite advances in diagnostics, definitive confirmation of FIP is often challenging and, unfortunately, in some cases can only be made after the cat has died through histopathological examination .

Treatment options for FIP-infected cats

The treatment of cats infected with FIP has made significant progress in recent years, mainly with the development of specific antiviral drugs. These drugs aim to fight the virus and strengthen the immune system. Among the best known is an antiviral drug that has proven to be particularly effective. It is important that treatment begins as early as possible to have the best chance of recovery. Your veterinarian can suggest the best treatment strategy based on your cat's health status.

In addition to antiviral medications, supportive care is an essential part of treating FIP. This includes:

  • A balanced diet to improve the cat's general condition.
  • Fluid intake to prevent dehydration.
  • Pain management to improve the cat's well-being.

These measures can help improve the quality of life of affected cats and increase their chances of recovery. It is crucial to work closely with your veterinarian and be consistent with all suggested treatments.

Preventing FIP: How to Protect Your Cat

To protect your cat from FIP, preventative measures are crucial. Good hygiene and careful management of multi-cat households can minimize the risk of infection. This includes providing separate litter boxes for each cat and regularly cleaning these, as well as all food and water sources. In addition, it is important to keep stress to a minimum for your cat, as stress can weaken the immune system and increase susceptibility to infection. By following these steps, you can help reduce the risk of your cat contracting FIP.

FIP vaccination: protection or risk?

The FIP vaccine offers some protection against the feline coronavirus that can cause FIP. However, it is not 100% protection. The vaccine aims to strengthen the cat's immune system so that it can better fight the virus. It is important to know that:

  • The vaccination is most effective in cats that have not yet had contact with the virus.
  • A prior blood test is necessary to check the cat's immune status.
  • Despite vaccination, a residual risk remains because the virus can mutate.

Overall, FIP vaccination can reduce the risk of severe disease, but cat owners should be aware that it does not provide absolute protection.

Life Expectancy in FIP: An Overview

The life expectancy of cats infected with FIP varies greatly and depends on several factors, including the form of the disease (wet or dry) and when it is diagnosed. In general, the prognosis for cats suffering from FIP is unfortunately often poor. Over 95% of cases are fatal, with life expectancy ranging from a few days to several months. However, there is some hope with new treatments that can improve quality of life and survival rates. The most important points for owners of cats suffering from FIP to consider include:

  • Early detection and diagnosis are crucial for potentially more effective treatment.
  • Supportive care , such as a balanced diet and hydration, can improve quality of life.
  • New treatments , including antiviral drugs, offer hope, although they are not available or approved in all regions.

Understanding these aspects can help owners make the right decisions for their cats with FIP and provide them with the best possible support.

Wet vs. dry FIP: symptoms and treatment approaches

The wet form of FIP causes fluid to build up in the abdomen or chest, which can cause a visibly swollen abdomen or difficulty breathing. Symptoms of this form are often more severe and include:

  • Strong growth of abdominal circumference.
  • Difficulty breathing due to fluid accumulation in the chest cavity.
  • Loss of appetite and weight loss despite visible swelling.

In contrast, the dry form of FIP is characterized by less or no fluid accumulation. Instead, affected cats experience inflammation and clumping of tissue in various organs, which can lead to a variety of symptoms, including:

  • Eye inflammation and changes in the iris in the ocular variant.
  • Neurological abnormalities , such as movement disorders or seizures, in the neurological variant.
  • Jaundice and anemia are other possible symptoms.

Hope through research: Latest findings on FIP
