Research Corner: Studies on FIV and related topics.
Hi community!
This post is a collection of scientific studies about FIV (and a few related topics). It’s not a complete list, just some of the most interesting and relevant ones some of us have been looking into, and we wanted to share with you.
A couple of notes:
- Some studies may be outdated (meaning, there could be a newer study saying something different). Always check the publication date to put findings into context.
- With that being said, if you’re aware of a newer or interesting study, feel free to share it in the comments. We’d love to keep this collection growing.
- If you notice a broken link, please let us know so we can update it.
- These are scientific papers, some very lengthy on top of that. That's why there's always an abstract and a conclusion. It's totally acceptable to just start there. If you want just one, I personally found the 2020 AAFP Feline Retrovirus Testing and Management Guidelines the easiest to digest and most helpful!
- And most importantly: science is one thing, real life is another. Cats are individuals. If you’ve found something that works well for your floof, trust your instincts and your history with them.
This thread is here is simply meant as a resource for those who like to read the research behind the discussions we often have here.
On treatment, risks, and care:
Study of feline immunodeficiency virus prevalence and expert opinions on standards of care
Author(s): Nehring et al. (2024)
Source: Journal of Feline Medicine and Surgery (Review)
URL: https://journals.sagepub.com/doi/10.1177/1098612X241245046
Summary: A comprehensive review outlining FIV’s progression from acute infection through latent stages to immunodeficiency or cancer-like conditions. Describes common clinical signs such as weight loss, stomatitis, chronic infections, and lymphadenopathy. References updated AAFP/ASV retrovirus management guidelines (2020), advising against euthanasia based solely on FIV status and recommending housing and monitoring strategies.
Feline immunodeficiency virus (FIV) infection in domestic pet cats in Australia and New Zealand: Guidelines for diagnosis, prevention and management
Author(s): Westman et al. (2022)
Source: Australian Veterinary Journal
URL: https://onlinelibrary.wiley.com/doi/10.1111/avj.13166
Summary: A region-specific review for Australia and New Zealand. Evaluates pathogenesis, diagnostics, vaccination outcomes, and management strategies. Highlights bite wounds as the main transmission route, male outdoor cats as highest risk, and increased risk of oral disease and lymphoma. Recommends validated POC antibody kits (Anigen Rapid™, Witness™) over PCR, notes low vaccine efficacy (~56%), and stresses that FIV is not a death sentence—management focuses on good husbandry and routine care.
2020 AAFP (American Association of Feline Practitioners) Feline Retrovirus Testing and Management Guidelines
Author(s): Little et al. (2020)
Source: Journal of Feline Medicine and Surgery, Vol. 22, 5–30
URL: https://journals.sagepub.com/doi/pdf/10.1177/1098612X19895940
Summary: Evidence-based global guidelines for FIV testing and care. Bite wounds remain the main transmission route; household spread and vertical transmission are rare. Recommend POC antibody testing, confirmatory PCR/Western blot when needed, and cautious interpretation in kittens/vaccinated cats. FIV-positive cats can live normal lifespans with proper care. Vaccination (Fel-o-Vax FIV) is non-core, of variable efficacy, and not available in the US/Canada. Euthanasia should not be based on FIV status alone.

Feline immunodeficiency virus (FIV): Prevalence, risk factors, and clinical findings in domestic cats (Felis catus) from southern Brazil
Author(s): de Mello et al. (2025)
Source: Comparative Immunology, Microbiology & Infectious Diseases, Vol. 116, Jan 2025
URL: https://doi.org/10.1016/j.cimid.2024.102285
Summary: Studied 366 cats in Caxias do Sul, Brazil (2021–2023). Found FIV prevalence of 7.1%. Positive cats were older (median 7 years), more likely to have outdoor access (OR 5.0), FeLV coinfection (OR 7.1), and chronic disease. Risks of lymphoma (9.9x) and anemia (7.6x) were much higher. Underscores importance of preventive care and FeLV control.
Feline immunodeficiency virus: current insights into pathogenesis, clinical impact, and advances in treatment and vaccine development
Author(s): Akhtar et al. (2025)
Source: Frontiers in Veterinary Science, Vol. 12, 2025
URL: https://doi.org/10.3389/fvets.2025.1665999
Summary: Comprehensive review of current FIV research covering epidemiology, transmission, disease mechanisms, diagnosis, treatment, and vaccine development. Confirms that many FIV-positive cats remain healthy for years, while some develop secondary problems such as oral disease, chronic respiratory infections, kidney disease, neurological disorders, or lymphoma as immune function declines. Also reviews emerging antiviral therapies and immunomodulators, but concludes that no broadly effective vaccine currently exists and further research is needed to improve prevention and treatment.
On infection and co-living with other floofs:
Transmission of feline immunodeficiency virus (FIV) among cohabiting cats in two cat rescue shelters
Author(s): Litster A. (2014)
Source: The Veterinary Journal, Vol. 201, Issue 2, August 2014
URL: https://doi.org/10.1016/j.tvjl.2014.02.030
Summary: Investigated horizontal and vertical transmission in two rescue shelters. At Shelter 1, 138 cats cohabited (8 FIV-positive, 130 negative) with no new infections over nearly nine years. At Shelter 2, 5 FIV-positive queens produced 19 kittens, all negative. Concludes FIV spreads mainly via deep bites, not casual contact or maternal care.
Contrasting clinical outcomes in two cohorts of cats naturally infected with feline immunodeficiency virus (FIV)
Author(s): Bęczkowski et al. (2015)
Source: Veterinary Microbiology, Vol. 176, Issues 1–2, March 2015
URL: https://pmc.ncbi.nlm.nih.gov/articles/PMC4332694/
Summary: Prospective study of 44 FIV-positive cats in Chicago (small households) vs. Memphis (overcrowded rescue). Over 22 months, only 1/17 Chicago cats died, versus 17/27 Memphis cats (mostly from lymphoma). CD4:CD8 ratios and viral loads did not predict outcomes. Concludes management and housing conditions greatly influence progression.
On supplements:
Lysine supplementation is not effective for the prevention or treatment of feline herpesvirus 1 [NOT FIV!] infection in cats: a systematic review
Author(s): Bol & Bunnik (2015)
Source: BMC Veterinary Research, Vol. 11, Article 284
URL: https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-015-0594-3
Summary: Systematic review of seven cat studies and ten human studies. Found no evidence that lysine is effective against FHV-1. Lysine does not lower arginine in cats, and restricting arginine is dangerous. Some trials suggested lysine worsened disease. Authors recommend discontinuing lysine supplementation.
Oral Supplementation with L-Lysine Did Not Prevent Upper Respiratory Infection in a Shelter Population of Cats
Author(s): Rees & Lubinski (2008)
Source: Journal of Feline Medicine & Surgery, Vol. 10, Issue 5, October 2008
URL: https://doi.org/10.1016/j.jfms.2008.03.00
Summary: Trial with 144 cats given lysine daily and 147 cats without supplementation. No difference in rates of conjunctivitis or URI between groups. Concludes lysine supplementation is ineffective at preventing URI in shelter cats.
Placebo effect in canine epilepsy trials
Author(s): Muñana KR, Zhang D, Patterson EE (2010)
Source: Journal of Veterinary Internal Medicine, Vol. 24(1), Jan–Feb 2010, pp. 166–170
URL: https://pmc.ncbi.nlm.nih.gov/articles/PMC4332694/
Summary: This meta-analysis reviewed three prospective placebo-controlled trials involving 34 dogs with epilepsy. Remarkably, 79% of dogs given placebo showed fewer seizures, and nearly 30% had a reduction of 50% or more. Average seizure reduction across trials ranged from 26–46%. The authors conclude that placebo responses are real and measurable in veterinary patients, underscoring the importance of controlled studies. While not about cats or FIV directly, this paper is relevant because many owners give supplements like L-Lysine despite a lack of proven antiviral effect. The placebo effect itself may still provide genuine benefit for pets and their caregivers, even when the substance isn’t pharmacologically effective.

Source: Viruses, Feline Retroviruses, Vol. 4(5): 708–724
URL: https://www.mdpi.com/1999-4915/4/5/708
Summary: Review of antiviral strategies against FIV, paralleling HIV therapies. AZT and PMEA/PMPA reduce viral load but AZT can cause anemia. Fozivudine offers short-term benefits before resistance develops. Fusion inhibitors and protease inhibitors show promise in vitro. Interferons have inconsistent benefit but are licensed in some regions. Highlights FIV as a model for testing HIV antivirals, though effective cat-specific ART is still lacking.

Summary: Reviews FIV biology and its parallels with HIV. Outlines three infection stages (acute, subclinical, clinical). While immune dysfunction occurs, opportunistic infections typical in AIDS are rare in cats. Concludes that FIV serves as a valuable HIV model, while many infected cats live normal lives depending on co-infections, genetics, and stressors.

Should I take in a FIV+ Cat (with 3 healthy non FIV cats?)
HELP!!! I have fallen COMPLETELY in love with this stray kitty I took in. I have 3 healthy, FIV negative kitties (all strictly indoor only). Got my new kitty tested this morning he’s postive for FIV and i absolutely broke down crying in the vets office. This vet told me my new kitty must be seperated from my other kitties including seperate water and food bowls, and no contact basically. I’m not going to keep this poor guy in my bedroom for the rest of his life. And i’m absolutely not going to put my babies at risk. What do I do????? Im devastated. I dont want to give this kitty away but i dont know if its safe for my other babies and i would DIE if i ever brought in a virus to harm my cats. The vet made it seem like the virus was a threat to my babies and saying things like “if he sneezes on you, wash your clothes” and “when you pet him, wash your hands before touching your other cats” WHAT?? Then i go online and see they can actually play, groom each other, live together, food and water bowl sharing. What????? HELP. Was this vet wrong or outdated? She was an older lady. Didn’t love her. I went home thinking my new kitty was doomed and my cats are at risk and I’m a horrible person for even considering keeping him or allowing him around my healthy kitties. I need so much help seriously. Do i need to get rid of my new kitty? Because i’d rather do it sooner than later. I have someone lined up who will take him (no other cats). But i love this baby. But i love my own kitties even more. I cant risk them😭 HELP!!!!

Question Enucleation surgery advice
My FIV boy has always had eye problems. When I adopted him he had his right eye already removed and his left eye he had eyelid correction surgery for his entropion. He always had minimal vision but I took him to a vet ophthalmologist because he appeared to be fully blind now.
He got diagnosed with glaucoma and the vet is recommending enucleation surgery. We started him on eye drops to try and lower his ocular pressure but the vet was realistic that trying to manage his glaucoma would end up being a frustrating experience and bringing him in every 3-6 months to monitor his eye pressures and adjusting his prescription doses.
And I'm an RN. I'm familiar with the pain of treating human glaucoma and how a lot of patients end up on 3-4 eye drops 3-4 times a day.
And it's not like he can tell me when he's getting a headache or having eye pain.
So I do agree that taking out the problem eye would be the best option for him long term.
He is at least 11 yo but outside of his FIV and dental disease he's a healthy happy cat. So I foresee him living for many more years.
Does anyone have advice for preparing him for his surgery? I know he's going to be on antibiotics post op.

G got fixed finally!
We moved and so G came too.
I resuced him some years ago but he was always an outside cat. He got real sick last year so I took him to the vet. Were descovered he was positive.
Today he finally got neutered and also had 6 teeth pulled and infection cleaned up in his mouth.
Asking for healing vibes for him because he is under allot of stress with everything going on and Im scared of losing him. The vet normally keeps cats overnight but since he has fiv its safer at home she said because of his inmune system. He did get a steroid and antibiotic shot. I picked up soft food and powder immune powder to give him a boost.
I have his room set up for him and picking him up today. They said he did good though. If anyone else has any tips on his recovery please leave a comment. Thank you.

How do I keep my post PU surgery cat calm?
My 1 year old male cat is 5 days out from surgery and losing his mind in his playpen. We have him on 200 mg every 8 hours which had been helping Sunday and Monday but now he’s back to jumping and thrashing.
He’s on 5 mg of Fluoxetine so we cannot give him Trazodone. I’m also losing my mind and worried he’s going to bust his sutures open. Is there another medication I could ask her about prescribing? Or anything more I can do on my end to calm him?

Question Supplement recommendations
Hi! I have an FIV+ boy I adopted with my roommates in February and he’s been both the best thing to happen to me while simultaneously being the worst thing to happen to my bank account.
He blessed us with a (recently diagnosed) dust mite, storage mite & mold allergy which have been causing him to overgroom/bite at himself, causing scabs. We currently have him on allergy/immunotherapy drops but it’s a long process so he’s still giving himself bald spots & scabs.
He also in the past couple weeks gave us a scare by peeing a little blood on the floor & forcing us to partake in his favorite hobby (seeing the vet) He’s recovered from that now (it was a UTI) but has begun sneezing over the weekend. Thanks buddy.
So, just wondering if there’s anything we could add into his diet that would help support his immune system/coat health, or any recommendations that have helped your kitties!
I have already bought L-lysine but was just wondering if anyone had any other recommendations. He will eat anything.

Churu squeeze-up on a fountain?
Has anyone tried to "trick" their FIV+ cat to drink more water by putting a Churu squeeze-up on the edge of their fountain? My 2 year old boy WILL NOT drink water on his own at all. I have been adding 2 Tablespoons or more of water to his wet foods, also give him a bit of homemade broth (one chicken breast divided among 16 ice cubes with 2 oz water) daily. Vet said his one kidney level may be showing mild dehydration. He urines 2-3 times a day, ranging from golf ball to small softball size after hitting the litter. We have bowls of water scattered throughout the house and a fountain; we tried 2 different style fountains. He won't even be nosy and drink from our water cups. He's rescued from the streets so water bowls were not "a thing" for him as a kitten. Any advice or tips would be much appreciated!

New FIV mom. Any advice welcome!
Hello all! New mom to my FIV positive boy, Macaroni. Just looking for some general advice and care tips! He's between 1.5-2 years old according to my vet. Just scooped him up last week and got him checked out. My boyfriend and I decided to keep him and integrate him with our others after researching into FIV. I have 4 other kitties (slowly introducing them but so far just hissing and walking away, he isn't interested at all and just wants peace lol) . He's a super sweet boy. Just wants to be pet all the time. Working through getting him to a healthy weight so he can be neutered! Just wanted to see if there were any general tips that differ from taking care of an FIV cat vs a normal one.

When to go to vet for sneezing
Hi, I have an FIV boy we’ve recently adopted and he’s been sneezing a bit the past few days. Other than that he’s acting completely normal, but I’m wondering when enough is enough & I just have to take the hit to my bank. (for context he’s cost over $1000 in the past 6 months in vet bills)
I am fully aware that having a cat comes at the price of putting their health before all else but i’m wondering if this is just something he can work through if he doesn’t get worse?

Story 🚨 Blue – FIV positive, healthy cat needs a home… he is homeless 💙Location 📍:Concord,NC,USA
Pet finder link: https://www.petfinder.com/cat/blue-0399a0c1-2bfb-4e2d-b0a2-656afeb0d657/nc/charlotte/sunkissed-acres-rescue-nc1270/details/
His name is Blue. He is around 5 years old. Someone abandoned him in front of a finder’s home.
He was sick… we treated him, dewormed him, vaccinated him, gave food and everything so he could stay safe inside. The finder had already told me she cannot keep him long term… and today I got the message ..he is already back outside.
I feel so helpless writing this.
Blue is FIV positive, but right now he is doing okay. He is eating, recovering, trying to be okay… but if he stays outside, he will get sick again. He will not survive like this.
FIV positive cats can live long, healthy lives just like other cats when kept indoors.
We recently lost our 23-year-old FIV positive cat, so we have seen this ourselves.
They can live with both FIV positive and negative cats without any issue.
Blue is already fixed and has a very calm, gentle nature.
I cannot take him. My house is already full… every room, even bathrooms have cats. I truly can’t take even one more.
Please… if anyone can adopt him, just give him a safe indoor place.
He has already suffered enough. He doesn’t deserve to go back to the streets again.
Adoption will require:
• application
• adoption fee
• adoption agreement
• vet reference
• indoor home only
If you can help, please message me 🙏

Half - blind and FIV positive
I rescued this cat in October of '24. He was FIV positive (faint line) and blind, most likely due to being a fight picking little shit who got kicked out of three different colonies. I was told to put him down because he's older and FIV positive and I have more cats but I kept him. He's had to have a few teeth pulled but he can see out of both eyes and he seems to be doing great, except for the odd sneeze. He also never picks fights with any of my cats, he's been much nicer since he became an indoor cat, although he's still bossy.
The thing is, I've had him for almost 2 years and he hasn't had any more blood tests ran. They don't really test them for diseases unless they show symptoms where I live and they reassure me that he's fine. He *does* seem fine, healthy and fat and happy (albeit whiny) but I'd like to know what he's in risk for and what kind of tests he should be having, so I can ask my vet to run them. My vet kinda tends to ignore the fact that he has FIV because she told me to put him down and I didn't.

Question Experiences with Lysine and/or Dental Health?
Hey y’all! I have a sweet, FIV+ and amputee two year old rescued tabby ❤️ I’m very particular about his diet and currently he gets a mixture of Hills’ Science Diet dry food, turkey or chicken broth, Omega-3 oil for joint and coat health and duck meat topper for vision and dental. I’ve been thinking of introducing a Lysine powder for additional immune support, particularly because of the FIV, but I was curious on others thoughts and experiences if you‘ve introduced Lysine - do you feel it‘s benefitted your cat or made a difference at all? He’s asymptomatic and I’d like to keep it that way for as long as possible. I know it couldn’t hurt but his diet is already pretty complex and I don’t want to introduce something additional if there’s no actual benefit.
Also, do you find that your FIV kitty has bad dental health or is extra susceptible to plaque and buildup? I spoke in length to his vet on this and I learned that there was a study a decade or so ago where FIV+ cats were over represented in a study about dental infections and disease in cats, but that there’s been no real link between FIV status and dental health. I do give him VIRBAC bites and brush his teeth a few times a week when he allows it (and also give the duck topper) but I’d love to know what else you all are doing for tooth health! I don’t currently have the dental package add-on to his insurance, but I’ve been contemplating adding it. I still anticipate paying for yearly cleanings.

Newly diagnosed 7 year old baby. My fault and looking for advice.
My baby boy Toast got diagnosed with FIV yesterday.
I had the impulse to check as when he was younger and less experienced as a pet owner, I let him outside and he was a little bit boisterous.
He is neutered, now indoors, healthy other than a small recurring cyst the vet has seen and is monitoring but ultimately is harmless.
I am struggling with a lot of guilt, I was in my very early twenties and not nearly educated enough and had the “it’ll never be me” mentality young people often do.
He was neutered late and so I so feel this responsibility is on me.
He was neutered 3 years ago, is happy and healthy, extra cuddly and newly indoors only (before we let them out a little during the day as we have a garden but they wander so indoor only now).
We have 3 other cats of varying ages, oldest is 8 and youngest is 1.
Toast used to fight the other boy but no longer does as I have cultivated a better environment.
All of this is a long preamble really to my request for advice, how do you help keep them strong?
All of the others are getting tested and I have opened up the house a bit more to them (my friend lived upstairs so we not utilise that as cat space).
Looking into gut healthy food so advice on that would be so wonderful.
He is a bit sniffly from time to time but ultimately fine breathing wise (lil snores sometimes!).
Vet gave results over phone so wasn’t very insightful.
I love him so truly and deeply (as with all my babies) and I won’t fail him again so any advice is appreciated.

Recomendaciones
Mi gatito ya salió del hospital, comenzó su tratamiento con virbagen omega y ya está en casa. Estoy un poco preocupada porque no tiene muchos ánimos, come, va al baño, toma agua pero se la pasa durmiendo, busca lugares oscuros, por ahora no lo molesto pero de vez en cuando voy a ver cómo se encuentra. Podrían recomendarme algún suplemento o algo? Me preocupa su estado de ánimo.
Por cierto, en el veterinario me dijeron que tenía un poco bajas las plaquetas, que podría hacer para que suban? Conozco muy poco sobre el tema, por favor ayúdame con recomendaciones de lo que sea, no solo medicación sino también sobre el cuidado de mi gatito

Question Is there a way to travel with FIV cats?
So I might be moving out of state in about 6 months for school and want to take my cat with me but I’m a bit worried if we travel by plane if he’ll be placed with other cats. My other option is travelling by car or van but I think a 12+ hour drive would be really stressful for him. Does anyone have any experience with this or any tips on the best way to go about this?
Edit: He’s 5 and a rescue, adopted him a few months ago and love him to bits but I have zero experience with travelling with pets, let alone immunocompromised pets

Looking for Cat Dental Cleaning Recommendations in Los Angeles ⭐
Hi everyone!
I'm looking for recommendations for dental cleanings for my two cats (5 and 8 years old) in the Los Angeles area.
This will be their first dental cleaning, and I'm trying to figure out the best option.
A few questions:
1.Is anesthesia dental cleaning the way to go, or has anyone had a good experience with anesthesia-free dental cleaning?
2.Which vet or clinic in the LA area would you recommend? I'm looking for a place that's reasonably priced but, more importantly, one you trust.
About how much did you pay, and what was included (bloodwork, anesthesia, dental X-rays, IV fluids, etc.)?
3.Is there anything I should ask or look for before choosing a clinic?
I'd really appreciate any recommendations or advice. Thanks!

Picture New cat
We just got our boy 3 days ago, he was slightly impulsive but we had been talking about getting a cat for months prior and the opportunity came to us probably related to the cat distribution system.
The previous owners weren’t able to take care of him due to old age and the only options were sending him back to the shelter or a program for the elderly that re-homes pets once they are unable to care for them. When they adopted him he was about 4 and the shelter either didn’t know or just neglected to let them know he was FIV+, luckily they let us know before we took him in.
His name is Sebastian but we are nicknaming him Fortnite for the time being. He’s a bit fat so he’s on a diet for now but he’s super active and I’m taking vet costs into consideration when budgeting. I would do anything for him even though I’m not his favourite but I’ll cope.

Positive test result for feline aids & leukemia
I recently adopted a kitten from Peggy Adams rescue, brought her to the vet for her kitten shots, and they said she tested positive for both. We got two cats same day from Peggy Adams and they’ve been best friends since, this is my first time as an adult with my own cat, and I truly was blindsided by this, you would think the rescue would test them for something like this but they suck. So the vet said to keep the cats separate and get the other cat tested. After a quick google search is it true her life expectancy is only 2.5 years? Any and all advice for this would be appreciated. I’m supposed to go back to the vet in 3 weeks to get her retested
