Feline Immunodeficiency Virus Infection

Animals Affected – Cat

General Information
Feline immunodeficiency virus (FIV) is strikingly similar to the human immunodeficiency virus (HIV) that causes AIDS. FIV is found in most parts of the world and studies have found antibodies against the virus from serum samples dating to the late 1960s. The virus is present in the saliva and infected cats spread the disease by biting. FIV does not spread to kittens while they are in the uterus but, rather, through the milk when they begin to nurse. Not every kitten in the litter will become infected. Although any cat may become infected, FIV is most common in male free-roaming cats that fight.

Infection with the FIV virus is divided into three stages: acute, subclinical, and the chronic clinical stage. The acute stage lasts 3 to 6 months and is characterized by mild illness. Intermittent short episodes of lethargy, decreased appetite, and fever are typical. Often this stage goes unnoticed.

The subclinical stage lasts from months to years. Affected cats appear healthy but their immune system continues to deteriorate. In the chronic clinical stage, the deterioration of the immune system predisposes infected cats to a variety of disorders. Chronic mouth infections, respiratory infections, intestinal disease, fungal diseases, eye diseases, diseases of the nervous system, cancers, and leukemia are common. Near the end of the disease, many cats develop a wasting syndrome and lose 20% to 30% of their body weight over a period of several weeks. With FIV infection, the average time from diagnosis to death is 5 years.

FIV cannot infect people or dogs, and owners of FIV-infected cats have no cause for alarm.

Important Points in Treatment

1. Currently there is no effective treatment for FIV infection. Therapy is supportive and/or specific for other infections.
2. As the disease is only spread by bites, infected cats are only a threat to cats they might fight with. Transmission through food pans, litter pans, or grooming is unlikely.
3. Limiting exposure to other cats is important. Because of the dysfunction of the immune system, infected cats are more likely to catch other diseases if they have contact

An Important Update From Animal & Bird Medical Center On COVID-19

We are committed to offering a safe and healthy environment for our clients, pets and hospital team here at Animal and Bird Medical Center. The best way to avoid becoming ill is to avoid exposure to the virus. Taking typical preventive actions is key.

In being cautious and mindful of everyone’s safety, we are actively working to minimize your exposure to crowded exam rooms and long waits in the lobby.

In response to the COVID-19 pandemic, we have made some changes to our protocols in-hospital for the time-being…

In order to limit exposure while still providing quality care for your pet, we will be implementing special protocols to keep you safe.

We will have our veterinary technicians get a history of the patient’s symptoms and owner’s concerns via phone prior to coming into the clinic.

  • Upon arrival, owners can call us from the curb in front of the clinic and we will have a technician assistant come to your car and bring your pet inside.
  • From here, your pet will be examined and the doctor will develop a treatment plan which he will then communicate via phone with the owner.
  • At the end of the visit, an invoice will be brought out to your car and payment can be taken via phone.

Our goal is for you to be able to bring your pet in for medical care but have no risk for you or our dedicated staff of transmitting the COVID-19 virus.

The Doctors and staff are dedicated to making sure your pet’s medical needs are taken care of during this national crisis.

We can still fill prescriptions for pick up, however, for those who prefer, non-narcotic and non-urgent prescriptions can be mailed to your home.

As always, careful hand-washing and other infection control practices can greatly reduce the chance of spreading any disease.
