Overview of Feline Infectious Diseases
Feline infectious diseases encompass a range of conditions caused by pathogens such as viruses, bacteria, and parasites. These diseases can have varying degrees of severity and can affect cats of all ages. Understanding the common infectious diseases in cats and their modes of transmission is vital for cat owners to protect their feline companions.
Common Infectious Diseases in Cats
Some of the most common infectious diseases that affect cats include:
-
Feline Leukemia Virus (FeLV): FeLV is primarily transmitted through contact with an infected cat’s saliva, nasal secretions, blood, urine, feces, or via in utero transmission and through milk. It can spread through bite wounds, mutual grooming, and sharing of litter boxes or food and water bowls. FeLV can also be transmitted from an infected mother cat to her kittens.
-
Feline Immunodeficiency Virus (FIV): FIV attacks the immune system of infected cats and is usually spread through a bite wound from an infected cat. Un-neutered male cats that are prone to fighting are at a higher risk. Transmission to kittens from an infected mother cat is less common.
-
Feline Panleukopenia (FP): FP, also known as feline distemper, is a highly contagious disease caused by the cat parvovirus. It primarily affects kittens and can lead to severe gastrointestinal signs, blood disorders, and neurological signs. The virus is shed in bodily fluids like saliva, urine, and feces and can also be spread via fleas.
These are just a few examples of the infectious diseases that can affect cats. Each disease has its own specific characteristics, symptoms, and treatment options. For more information on the symptoms of bacterial infections in cats, you can refer to our article on symptoms of bacterial infection in cats.
Transmission of Infectious Diseases
The transmission of infectious diseases in cats can occur through various routes. These include:
-
Direct contact: Infectious diseases can be transmitted through direct contact with an infected cat’s bodily fluids, such as saliva, nasal secretions, blood, urine, or feces. This can happen during mutual grooming, fighting, or sharing of litter boxes, food, and water bowls.
-
In utero transmission: Some infectious diseases can be transmitted from an infected mother cat to her kittens during pregnancy.
-
Fleas and ticks: Parasites like fleas and ticks can carry and transmit certain infectious diseases, including feline panleukopenia.
It’s important to note that zoonotic diseases, which can be passed from cats to humans, are also a concern. These diseases include ringworm, toxoplasmosis, and bartonella. For more information on zoonotic diseases, you can refer to our article on zoonotic diseases in cats.
Understanding the mechanisms of transmission for these infectious diseases is crucial for preventing their spread. By taking appropriate precautions and seeking timely veterinary care, cat owners can help safeguard their feline companions from these contagious diseases and maintain their overall health and well-being.
Feline Leukemia Virus (FeLV)
Feline Leukemia Virus (FeLV) is one of the most common communicable diseases in cats, affecting roughly 3% of all cats in the United States (Best Friends Veterinary Center). Understanding the transmission and risk factors associated with FeLV, as well as recognizing the clinical symptoms and effects, is crucial for cat owners.
Transmission and Risk Factors
FeLV is commonly transmitted through contact with another cat’s infected saliva, nasal secretions, blood, urine, feces, in utero, and via milk. Cats can become infected through bite wounds, mutual grooming, sharing of litter boxes, or sharing food and water bowls. The virus can also be transmitted from an infected mother cat to her kittens (Better Vet).
It’s important to note that FeLV is highly contagious, and even casual touch with an infected cat can lead to transmission. Cats that spend time outdoors, have frequent contact with other cats, or live in multi-cat households are at a higher risk of contracting FeLV (Covetrus).
Clinical Symptoms and Effects
FeLV can have a significant impact on an infected cat’s health. It can lead to cancer, blood disorders, and immunodeficiency. Clinical signs of FeLV may include:
- Loss of appetite
- Weight loss
- Enlarged lymph nodes
- Fever
- Infections of the skin, urinary bladder, and upper respiratory tract (Covetrus)
It’s important to note that infected cats may not show symptoms immediately. Some cats can remain asymptomatic carriers of the virus, while others may develop severe symptoms and complications.
Regular veterinary check-ups, vaccinations, and minimizing exposure to potentially infected cats are key preventive measures for controlling the spread of FeLV. Testing for FeLV is recommended, especially for newly adopted cats or those with potential exposure to the virus. Early detection and appropriate management can help improve the quality of life for infected cats and reduce the risk of transmission to other feline companions.

Feline Immunodeficiency Virus (FIV)
Feline Immunodeficiency Virus (FIV) is a contagious disease that affects the immune system of infected cats. Understanding the mode of transmission and the impact on infected cats is essential in managing and preventing the spread of this virus.
Mode of Transmission
FIV is primarily spread through a bite wound from an infected cat, usually during aggressive fights between cats. Un-neutered male cats that are prone to fighting are at a higher risk of contracting the virus. Transmission from an infected mother cat to her kittens is less common but can occur during birth or through nursing.
It’s important to note that FIV is not easily transmitted through casual contact, such as sharing food bowls or grooming. However, it is crucial to prevent the spread of the virus by keeping infected cats separated from non-infected cats to avoid potential fights and bites.
Impact on Infected Cats
FIV attacks the immune system, leaving infected cats susceptible to various infections and illnesses. After exposure to the virus, cats can have a long period of latency where they may not show any symptoms (Covetrus). However, over time, the immune system weakens, leading to the development of clinical symptoms.
Common symptoms of FIV include:
- Enlarged lymph nodes
- Fever
- Anemia
- Weight loss
- Disheveled coat
- Poor appetite
- Conjunctivitis
- Diarrhea
It’s important to note that the life expectancy of cats with FIV is usually shorter than that of non-infected cats. Most felines do not survive beyond five years following diagnosis. Regular veterinary check-ups and proper management of the cat’s health can help improve their quality of life and manage symptoms effectively.
To prevent the transmission of FIV, it is recommended to have all cats tested for the virus, especially when they are young. Infected cats should be kept indoors and separated from non-infected cats to prevent the spread of the virus. Additionally, spaying or neutering cats can help reduce aggressive behaviors and the risk of fighting, which can lead to FIV transmission.
Understanding the mode of transmission and the impact of FIV on infected cats is crucial in preventing the spread of this contagious disease. By taking appropriate precautions and working closely with a veterinarian, cat owners can ensure the health and well-being of their feline companions.
Feline Panleukopenia (FP)
Feline Panleukopenia (FP) is a highly contagious and potentially life-threatening viral disease in cats caused by the cat parvovirus. This disease primarily affects kittens and can lead to severe gastrointestinal signs, blood disorders, and neurological signs. It is important for cat owners to understand the nature of this disease in order to protect their feline companions.
Understanding the Disease
Feline Panleukopenia (FP) is caused by the cat parvovirus, which is highly contagious and present everywhere in the environment. The virus is shed in bodily fluids like saliva, urine, and feces, making direct contact with an infected cat or contaminated environment a potential source of transmission. Additionally, fleas that have bitten an infected cat can also spread the virus.
The cat parvovirus infects and kills rapidly growing and dividing cells, particularly those found in bone marrow and intestines. This has a significant impact on the immune system and the digestive system of affected cats. Kittens are particularly susceptible to the disease due to their underdeveloped immune systems (Covetrus).
Symptoms and Severity
Feline Panleukopenia (FP) can manifest with various symptoms, and the severity of the disease can vary. Common signs of FP include loss of appetite, high fever, lethargy, vomiting, severe diarrhea, nasal discharge, and dehydration. Some cats that contract the virus may experience a sudden and rapid decline in health, leading to death.
It is important to note that FP is a serious disease that requires immediate veterinary attention. Diagnosis of FP is usually based on clinical signs, history, and laboratory tests. Treatment typically involves supportive care, including fluid therapy and medications to manage symptoms. However, prevention through vaccination is the most effective approach to protect cats from this contagious disease.
By understanding the nature of Feline Panleukopenia (FP), cat owners can take necessary precautions to prevent the spread of the virus and seek prompt veterinary care if their cat displays any of the symptoms associated with this disease. Regular vaccination and maintaining a clean and hygienic environment can help safeguard the health and well-being of cats, especially kittens who are most vulnerable to this highly contagious disease.
Feline Infectious Peritonitis (FIP)
Feline Infectious Peritonitis (FIP) is a rare but serious disease that affects less than one percent of all cats. It is caused by the cat coronavirus, and while infection with the coronavirus is common and often asymptomatic, FIP is a rare mutation that is almost always fatal. This disease is most prevalent in multi-cat households, animal shelters, and breeding facilities.
Cause and Transmission
FIP is caused by the cat coronavirus, which is shed by infected cats in their feces. The transmission of FIP occurs when another cat ingests the virus shed by an infected cat (Better Vet). Crowded and stressful conditions, such as those found in multi-cat households or breeding facilities, can facilitate the spread of the virus (Best Friends Veterinary Center).
Diagnosis and Prognosis
Diagnosing FIP can be challenging as there is no easy and accurate test for this disease. Veterinarians rely on a combination of clinical signs, history, physical examination, and laboratory tests to make a tentative diagnosis. However, definitive diagnosis often requires a post-mortem examination.
Unfortunately, FIP is typically fatal, and there is no known cure for the disease. The prognosis for cats diagnosed with FIP is poor. Treatment options are limited to supportive care, aimed at managing the symptoms and improving the cat’s quality of life for as long as possible. However, the ultimate outcome is usually not favorable.
It’s important for cat owners to be aware of the signs and symptoms of FIP, which can include a persistent fever that does not respond to antibiotics, weight loss, lethargy, and loss of appetite. If you suspect your cat may be showing symptoms of FIP, it is crucial to consult with a veterinarian for a proper diagnosis and guidance on managing the disease.

Zoonotic Diseases in Cats
Cats can sometimes carry diseases that are transmissible to humans, known as zoonotic diseases. It’s important for cat owners to be aware of these diseases and take necessary precautions to protect themselves and their families. In this section, we will discuss three common zoonotic diseases in cats: ringworm, Bartonella infection, and toxoplasmosis.
Ringworm, Bartonella, and Toxoplasmosis
-
Ringworm: Ringworm is a fungal infection caused by a group of fungi. It can be transmitted by contact with an infected cat’s skin or fur. Infected cats continuously drop fungal spores from their skin and fur, which can remain capable of causing infection for many months. Children are particularly at risk of infection. Symptoms of ringworm in humans include itchy, red, and circular rashes on the skin. Treatment involves the use of topical antifungal ointments or oral antifungal medication. To reduce environmental contamination, infected cats should be confined to one room until they are free of infection, and the household should be thoroughly cleaned and disinfected. For more information on ringworm, visit our article on bacterial infection in cats.
-
Bartonella infection: Cat scratch disease (CSD) is caused by a bacterium called Bartonella henselae, which may be carried in the saliva of infected cats and in the bodies of cat fleas. It is usually transmitted from cat to human via scratches, bites, or when a cat licks open wounds of a person. Approximately 40 percent of cats are infected with Bartonella henselae, but most show no signs of disease. Precautions to reduce the risk of CSD include avoiding scratches and bites, washing hands after playing with cats, controlling fleas, and keeping cats indoors. In rare cases, complications can occur, such as the spread of bacteria through the bloodstream and infection of heart valves. For more information on Bartonella infection, visit our article on symptoms of bacterial infection in cats.
-
Toxoplasmosis: Toxoplasmosis is caused by the parasitic protozoan Toxoplasma gondii. It can be transmitted to humans through contact with infected cats’ feces or by eating undercooked or raw meat. Cats can shed the parasite in their feces for up to two weeks, and once shed, the parasite can persist in the environment for many months. Most healthy individuals experience mild flu-like symptoms or no symptoms at all. However, pregnant women and individuals with weakened immune systems should take extra precautions. To prevent the spread of Toxoplasma from cats to humans, it is important to wear gloves when handling potentially contaminated material, wash hands thoroughly afterwards, and cover children’s sandboxes when not in use to prevent cats from defecating in them. To learn more about toxoplasmosis, visit our article on bacterial infection in kittens.
By being aware of these zoonotic diseases and taking appropriate preventive measures, cat owners can ensure the health and well-being of both their feline companions and themselves. Regular veterinary check-ups, proper hygiene practices, and maintaining a clean living environment are key to minimizing the risk of transmission. If you have any concerns or suspect that you or your cat may have been exposed to a zoonotic disease, it is important to consult with a healthcare professional or veterinarian for guidance and treatment options.
