Feline Immunodeficiency Virus (FIV)

Feline immunodeficiency virus (FIV) is comparable to AIDS in humans and is often found simultaneously occurring in cats with feline leukemia virus (FeLV). Similar to AIDS, FIV is present in blood, cerebrospinal fluid, and saliva. The most common transmission of the virus is through a cat fight or during pregnancy as an infected mother passes it to her offspring. In very rare cases, a cat may contract FIV through saliva. Feline immunodeficiency virus is a slowly progressing virus and cannot survive outside its host.

FIV is species-specific, meaning it cannot be acquired from another species, nor can it be passed to another species; it only occurs within cats. Male cats are almost twice as likely to acquire feline immunodeficiency virus, reflecting their propensity to roam as well as quarrel with other cats.

Common illnesses that may occur simultaneously: 

  • Diarrhea
  • Eye disease
  • Fever
  • Neurological problems
  • Pneumonia
  • Sinus infection
  • Skin disease
  • Swollen lymph nodes

Diagnosing and treating FIV

The veterinarian can diagnose feline immunodeficiency virus using a blood test that can detect specific antibodies within the bloodstream. Likely, a second test will be performed called a Western Blot Test to confirm the diagnosis.

After a positive diagnosis is established, there is not much that can be done by means of treatment. Treatment is focused on keeping the cat indoors and away from other cats, preventing the pet from contracting secondary illness and acquiring any sort of infection. FIV-positive cats are capable of living somewhat normal lives when kept in good health and when FIV is detected in earlier stages.

Currently there is a non-core vaccine available for FIV; however, there is controversy surrounding the vaccine due to the fact that inoculated cats test positive with FIV because current FIV antibody tests cannot distinguish between the disease and the vaccination antibodies. Be sure to inform your veterinarian if your cat has obtained the FIV vaccine.

If you have any questions about feline immunodeficiency virus or the FIV vaccine, please contact our office.

Here's a vet that still cares.
Just wanted to say I love Dr. Petcu's staff and his compassionate , caring way of taking care of my dogs.The staff is not only friendly and professional ,they know who you are when you arrive ,and they actually love animals. Is the first Animal Hospital that my dogs are at ease and feel comfortable.The place is very clean and the reception area very elegant and inviting. Exquisite services and Dr. Petcu always take his time to explain the disease and options and still finds time to play with my dogs. He's always treated both his animal and human patients with compassion and dignity,and would never recommend procedures unless he truly feels your pet will benefit from it. One of the vets that cares for your pet. The prices are reasonable and the services exceed all expectations. I Highly recommend Dr.Petcu and his hospital.

Western Animal Hospital AMAZING! Western Animal Hospital is the best place in the valley .The staff is professional, friendly, caring and accommodating. The hospital is very clean and upscale. The customer service and the provided services are outstanding.Dr. Petcu is one of the most professional veterinarians that i have ever met in my 25 years of pet parenting. I drive across the valley just to see him( i live in Anthem) .He really cares about his animal patients and it shows in every visits . He is very knowledgeable , compassionate, friendly and always takes the time to answer any question i have and explaining in detail any situation we are dealing with. I had my share of visits to many animal hospitals in the valley but none of them had the last technology as Western - digital X-ray ( they send you home with a cd for you x-ray records ) every room has a computer monitor where the x-ray shows and Dr. Petcu can review with me every detail of it. Also they have the laser surgery and digital dental x-ray. Dr. petcu is one of the most
courteous and pleasant Vets I have ever met. The prices are more than reasonable and also they try to accommodate everybody. I cannot recommend them enough. You can rest easy knowing your pets are in their care.I STRONGLY RECOMMEND THIS HOSPITAL - THEY HAVE A CUSTOMER FOR LIFE IN ME! very good !

.the best vet I met !! Pam M. 5 Western Animal Hospital - we are bringing our pets to Dr Petcu for 8 years. He was always helpful, many times we did not have the funds to treat our pets but he was fine with us paying when we had the money. He saved our cats in many instances and all I have to say is that I greatly reccomend Western Animal Hospital for any responsable pet owner .
