What Does It Mean When a Cat Is FIV Positive?


If you’ve ever seen “FIV positive” listed on a cat’s profile, it’s understandable that it could seem intimidating.


But the reality is, it’s not nearly as scary as it sounds.


FIV stands for Feline Immunodeficiency Virus. It’s a virus affecting between 2.5-5% of healthy cats in North America that can weaken a cat’s immune system over time, which means they may be more prone to infections.


However, most cats with FIV can live long, happy lives, often without major health issues for years. 


According to the Cornell Feline Health Center, “Though there is no cure for FIV, recent studies suggest that cats with FIV commonly live average life spans, as long as they are not also infected with feline leukemia virus.”


This means many FIV+ cats can still have a great quality of life, and many remain healthy for a very long time!


How FIV Is (and Is Not) Transmitted


One of the biggest misconceptions about FIV is how easily it spreads.


FIV is transmitted through deep bite wounds, most commonly from serious fighting between cats.


It is not spread through everyday contact, including:

  • Sharing food or water bowls

  • Sharing toys

  • Grooming 

  • Snuggling or simply living together


In stable households where cats get along, the risk of transmission is low.


This is why it can be possible to successfully integrate FIV-positive cats into multi-cat households as long as there is no history of aggression or rough fighting between housemates. It can also be a great option to adopt multiple cats who are FIV+ so they may live together without any risk of spreading to non FIV cats.


What Kind of Care Do FIV-Positive Cats Need?


Caring for an FIV-positive cat is often very similar to caring for any other cat, with a few additional considerations.


Because their immune system can be more vulnerable, it’s very important to:

  • Be alert for signs of infection

  • Seek veterinary care promptly if something seems off

  • Keep up with regular veterinary exams

  • For those FIV cats who do need treatment, vets can prescribe antiviral agents and support medications when needed, which can often help


How is FIV Identified?


FIV is diagnosed through bloodwork at a veterinary clinic. For any cats adopted through Underdog Pet Rescue, all Undercats 6 months old and older are tested prior to adoption.

Having access to affordable veterinary care can make a big difference for adopters and cat owners.


Through Underdog’s nonprofit vet clinic, we’re able to support foster and adoptive families, along with the wider Madison community with ongoing care, helping to ensure these cats stay healthy.

Changing the Narrative Around FIV


At Underdog, we see firsthand how incredible these FIV cats are.


They are often playful, affectionate cuddle bugs just as deserving of homes as any other cat.


FIV is not a reason to overlook a cat. It is simply one part of their story.


When we shift the focus from fear to understanding, more cats get the chance they deserve.


Considering Adopting an FIV-Positive Cat?


If you’re open to it, adopting an FIV-positive cat can be one of the most impactful ways to save a life.


These cats often wait longer for adoption despite being just as loving and social.

And with the support of Underdog’s veterinary team, which makes vet care more accessible, adopters are not navigating this alone.
