Cats + Infectious Diseases

  • Tularemia is an infection of the bacteria Francisella tularensis and is most common in rabbits and rodents. Infection in cats occurs from ingestion of an infected animal, contaminated water, or the bite of a blood sucking insect. Tularemia causes acute illness, enlarged lymph nodes, abdominal pain, jaundice, and organ system failure. Diagnosis includes physical exam, baseline bloodwork, and urine tests, as well as paired serum titers. PCR can also be used to identify the bacteria in a blood sample. Treatment requires hospitalization and supportive care including IV fluids and antibiotics. Prognosis is guarded to poor depending on how early treatment is initiated. Tularemia is a reportable zoonotic disease.

  • Uveitis is an inflammation of one or more of the structures making up the uvea. It can be very painful and can lead to blindness. It may be a primary condition or a sign of an underlying condition. The usual signs of uveitis are severe pain with an intense reddening of the visible parts of the eye. The eye is usually kept shut and most pets avoid bright lights. Diagnosis will include a thorough physical exam along with other tests to determine if there is an underlying condition. Treatment is initially aimed at reducing inflammation and providing pain relief and may include other treatments if an underlying condition is identified.

  • There are five primary reasons for vaccination failure. Vaccine inactivation is one reason and is most commonly caused by warming during shipping and handling. In addition, vaccines are not always 100% effective. Cats may also be unhealthy or too young, leading to vaccine failure. Interference by maternal antibodies can lead to the vaccine being blocked. Lastly, cats receiving overwhelming exposure to a virus may have a failure in the effectiveness of the vaccine.

  • Vaccines are necessary to reduce infectious disease-caused illnesses in cats. They work by stimulating the body's immune system to recognize and fight a particular microorganism such as a virus, bacteria, or other infectious organisms. Depending on the disease, the vaccine will help the body prevent infection or lessen the severity of the infection and promote rapid recovery. The American Association of Feline Practitioners has established vaccination guidelines for cats, some of which depend on a cat's lifestyle and where it lives.

  • Regular preventive health care for your cat can increase the length and quality of her life. Healthcare guidelines are established and kept up to date using the most recent evidence-based recommendations including the recommendation that all cats receive a complete veterinary examination at least once a year or more frequently, depending on their individual needs and health concerns.

  • A zoonosis is a disease or infection that can be transmitted from animals to humans. Although cats only pose a mild risk of causing disease in humans, those with immunosuppressive conditions such as HIV or those receiving chemotherapy are at higher risk of becoming ill from these infections. The most common and significant infections that humans can get from their cats include rabies, cat scratch disease, toxoplasmosis, and ringworm. Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are not zoonotic. Hygiene plays an important role in preventing the spread of these diseases, as well as preventive medicine for your cat, including regular deworming and external parasite preventives. Keep your cat indoors to minimize exposure to zoonotic diseases.
