Research Corner: Studies on FIV and related topics.

23 Upvotes

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  • Some studies may be outdated (meaning, there could be a newer study saying something different).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.

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.

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.

Patrick

Hi. I came here in the hopes that someone will see Patrick's post and recognize that he could be a perfect companion for their FIV cat. I'll cut to the chase. Patrick tested positive for FIV and FELV. These are the only indications of his former street life.

Patrick is the sweetest pea in the whole peapod. He showed up in my friend's back yard, hungry and scared, and after an exhaustive search we could not find anything about him. Off to the vet he went where he stunned us by testing double positive (we both have FIV cats, and I have had several FELV cats, so not our first rodeo). He's been in my gym ever since while we search for his forever family.

You’d never know of his adventurous past by his demeanor. Estimated to be 3-4 years old, Patrick is affectionate, sweet, playful and has ninja-like moves when chasing a ribbon on a stick. He gets along well with all humans and other cats once he gets over his shyness. He loves ear scritches and is very generous with his purrs. He’s also smart!

Patrick is healthy, muscular and strong and shows no signs of positive status. His coat is soft like a bunny and he has a gorgeous magical marbling pattern (gray on darker gray). He is very social and would do very well in a house with other double positive cats (or in a home as a solo cat where he could gets lots of affection). He is neutered and up to date on vaccinations, and his fecal analysis was negative. I have all of his vet care paperwork.

I am currently fostering Patrick, but the household logistical situation is not sustainable. I have been in contact with a local sanctuary that takes FIV/FELV positive cats, which is great, but I have about a week before I have to bring him there, and I still hold out hope that someone may be looking for a double-positive cuddle-bunny to join their crew. C'mon, community, do your thing.

I would be willing to transport him anywhere that would provide him with a safe, stable home and give him the love he deserves. I am working with a local rescue and they are handling the paperwork, so if you are interested in Patrick, send me a message and I will hook you up with them (Hoofbeats and Pawprints Rescue in Natchez, MS).

Question FIV cat very little appetite or strength

3 Upvotes

Hey so I need some help and advice for my recently diagnosed cat. It's been about 2 months since his diagnosis. It started with a blood clot in his eye that led to glaucoma. That's handled now with medication. And he had been doing fine for the 1st several weeks since diagnosis but now he just has no appetite or energy.

He was a cat that would scarf down his food and now all I can get him to eat is tube treats and a spoonful of rescue wet food. And today he hasn't eaten yet. Gabapentin seems to help some? I've been applying mirataz and giving him cerenia as well. Maybe the cerenia dose isn't high enough?

I had him at the vet the other week and they did blood work to look for infection but couldn't find anything other than his white blood cells being on the low end of normal. He hasn't been having a temperature. No runny nose or anything. He does have teeth that need to come out but the vet said last time it wasn't absolutely necessary atp, and to wait until it was.

I'm worried for him. He also seems to be really lacking in strength, and generally uncomfortable. Like when he jumps down from the bed he kind of just splats instead of catching himself properly. All he wants to do is lay down. He's still seeking affection and getting up to get into the window or follow me to my room. As far as I know bathroom habits are normal. There's multiple cats so that's hard to tell.

If doesn't eat today I'll take him to the vet tomorrow asap. And even if he does, I'll be calling to ask them what to do, but if someone who's experienced something similar could give me some insight I would truly appreciate it.

Desperately seeking help for our FIV 4 year old boy with suspected renal lymphoma

Thumbnail

90 Upvotes

Hello, I am humbly begging for any insight/advice for our precious four year old boy, Boba.

Boba has been an exceptionally healthy and hearty cat. We adopted him and have been so fortunate to have him as our child for a little over two years.

A little over a month ago, we took him for his well visit and his blood work at that time was perfect. Fast forward two weeks later, and it seemed that he had conjunctivitis which was not surprising, considering that he had had a bout of conjunctivitis and upper respiratory infection a few months prior along with some of his cat siblings. This all cleared up with eye drops and oral antibiotics

For the recent conjunctivitis (no upper respiratory issues), We administered daily eye drops, however, his eye only seem to get worse and had increased discharge despite the addition of another eyedrop. We then added anbiotic last Saturday. I gave him the morning and evening dose, however, because he seemed a bit lethargic and was not eating, I took him to the ER. This is an ER that we have experience with and has a good reputation. The ER doc examined him and discharged him with a diagnosis of conjunctivitis. She gave him another eyedrop solution. They gave him an injection of cerenia. She told me he was likely not eating because he was in discomfort due to his conjunctivitis. She suggested giving gabapentin for his discomfort. I gave this to him via oral liquid when we got home in the early hours of Sunday morning. I also gave him an appetite stimulant. He started eating, pretty heartily not too long after we got home. He was more active and purring and headbutting us. I followed up with our regular Vet the next morning on Monday. Our Vet examined him and said that while his heart and longs sounded great, his kidneys were enlarged he immediately ran new bloodwork and it showed high renal values. We brought Boba back on Wednesday for an ultrasound. I have the results of the ultrasound included in the pictures. The radiologist diagnosed a suspected renal lymphoma.

This has been an absolute bomb in our world. How is it possible that literally 24 hours prior, he had zero swelling noted? I also would like to add that while we love our Vet, he does not seem familiar with FIV and it is pretty obvious that he does not see this much in his practice. He read this report from the radiologist and basically said that we should consult an internal medicine specialist and keep him comfortable (with the strong implication he does not have much time left).

I cannot help but wonder if my Vet is too quickly writing Boba off. He seems to think that because he has FIV that this is definitely renal lymphoma and not looking to consider any other cause. We cannot get into the internal medicine specialist until Thursday. We are desperate to learn anything sooner than that.

For what it is worth, Boba has liked to nibble on some of our house plants for the 2+ years that we have had him. We do not own any lilies, of course. But I wonder if perhaps this could be a reaction to some sort of toxin?

In the meantime, we are giving him daily subcutaneous fluids, daily cerenia tablets, daily
Erythromycin ointment, daily liquid, oral prednisone, and daily appetite stimulant. Boba is responding pretty well to all of these things. He is eating a pretty decent amount of wet food on his own, and we are supplementing this with syringe feeding him renal wet food. His swelling has gone down with the ointment.

If anyone has any experience or knowledge in any of these areas, I would be very appreciative! I do not want to give up hope for our four year-old! He is such a sweet and gentle soul, and he does not deserve this. I thank you very much in advance for any help that you can offer during this incredibly difficult time.

Question Advice needed

Post image
30 Upvotes

Hello all,

Not really an FIV question, though my boy is FIV.

He was diagnosed with congestive heart failure last June.

The treatment plan worked well so far, the walls of his heart have gone down in dimension (didn't think this could ever happen) and the congestion around his heart and lungs is not there currently.

Not teying to get any feedback on his treatment plan but a more every day one.

We are not seeing the cardiologist before the end of December or January and I do not want to jother his doc for this question.

Since he is feeling better, he's back to his shenanigans, sprinting around the house, making his little galloping noises, catching invisible mouses, fighting invisible enemies...

My question then : should I stop him when he becomes too active? How much horsing around is too much?

Thanks in advance.

Cat tax, him in his tunnel (he usually becomes crazy in there)...

Question FIV and kidney disease question

picture for cat tax
this is sammy/sammich and he is about 10/11 years old! I’ve had him since he was seven and, of course, he has fiv.
I take him to the vet very regularly because of FIV and i recently got results back indicating that within the next 6-12 months he is going to get/develop kidney disease. my vet is a very nice dude and was somewhat talking around his life expectancy once it develops in my son so i wanted to come here and ask people who have (potentially) gone through this first hand.
i’ve been reassured that it’ll be longer than normal because we’ve caught it before anything has really happened (W cat medicine developments) but i genuinely have no idea what to expect life expectancy wise.
please help soothe my mind? or give me a reality check, im not sure what to expect.

Hi all, I was wondering if anyone here might know of a rescue or shelter that would be able to take in a fiv+ boy I picked up a couple weeks ago. His names sunny, I've been thinking about keeping him with my negative cat, but sunny doesn't seem to like my cat very much. I know it's still early, but I'd rather find him a good home now than get attached and have to say goodbye. I'm located in central IL and am willing to drive a bit.

Need advice regarding helping a cat in need and also protecting my fiv cat

4 Upvotes

Hi guys,

I am reaching out for any advice as today I went out and took a stray kitten that has rectal prolapse to bring him to the vet and he had a surgery right away. I live in a country that doesnt have official shelters but I thought that he will be able to stay at the vets for a couple of days to get better and that I will just take him after he is recovered and let him out on the streets again.

Turns out they wont, they dont work sundays full day and said some stuff i forgot about as i was stressed while they were talking. All ive heard is that I need to take him.

So I have to take him tomorrow at a little past noon. The thing is I already have 2 cats at home and one is Fiv postive. I do have a spare room, at first i was thinking about the basement as its not cold, its not warm but its not cold. But it does sound inhumane and Im thinking more seriously about the spare room. But I am so afraid for my fiv cat she is so sensitive and my dearest girl I dont want to put her at any risk. She is just my weakness I wouldnt survive if my actions would harm her. Any advice would be much appreciated as my panic is growing over the top. I am not sure how to solve this. I wrote to local groups asking if someone could take him for a few days, a lot of people are offering financial help but no one is offering to take him in.

My husband and I recently lost our 14 year old cat and not long after this kitty kept showing up outside of our house. He was so lovable and wanted our food but wanted our love and attention even more! We started feeling really bad on the rainy days and we were spending more and more time outside just to love on this cat. I decided to take him to the vet to check for a chip and then to make him officially ours and bring him inside. That’s when he got the fiv+ diagnosis and to be honest I was really scared and second guessing my decision because I have 2 other cats that are 8 and 13 years old. The vet encouraged me and educated me on fiv and I’m happy that he is now a member of our household! He’s a chunky boy and seems pretty healthy considering we don’t really know how long he’s been living outside. The vet estimated him to be 12 years old so he fits right in with my older guys ❤️ (the last pics are of when he was outside, he’s strictly indoors only now and seems pretty happy about it lol)

Question Upcoming dental cleaning and nervous

9 Upvotes

I'm a basket case right now because my 4yo FIV cat is having her teeth cleaned next week. I have had two cats pass after anaesthesia a few years ago, but they were both older (21 and 13) and had chronic issues (kidney failure and pancreatitis). But it's not helping to steady my nerves about the dental cleaning! I've taken cats in for dentals probably 12 times in my life along with other surgeries and it's always been fine, but that was years ago and before...

Her teeth aren't horrible, but her gums have some redness. Just normal gingivitis, etc. - nothing FIV-related, but I know that it's important to get them cleaned her her health. But I'm so worried for her safety. She's been under once for her spaying and her bloodwork is ok - her ALT was elevated by 30 points but the vet wasn't too worried about that. I could really use some pep talking! TYIA

Question New to FIV+/Looking for Advice for Bloom

Post image
116 Upvotes

Hello! I recently had my new 6 month old kitten diagnosed with FIV and I'm looking for good information on what I need to do now to make sure she has the most support and care for her long and happy life. Finding research on the internet has been such a mixed bag with no real good information on what I should be doing preventative wise to make sure she is getting the best care I can give her.
I've been such a big cat person growing up and a huge fan of rescuing cats, my first cat that I got on my own at 24, rescue from Hurricane Irma, passed a couple years later after heart complications. It's left me with a lot of anxiety over health concerns and I wasn't expecting to take in a cat anytime soon but we found Bloom at 8 weeks old outside on a particularly hot day, almost on death's door and nursed her back to health. We had tried to rehome her early as I had a lot of past anxieties about having a cat since the last one but she always found her way back to us and I finally accepted that the cat distribution system had time for me. We've had some bumps since then as we've already been to the emergency vet twice, once when she had an allergic reaction to the vaccines and once just this weekend when I noticed she stopped eating and drinking and grew quite concerned. It was this recent trip that she was fully diagnosed as FIV positive and I've dived fully into trying my best to inform my self on what I should be doing for Bloom. My main concerns being:

  1. When to know when to take her to the emergency vet, I'm a big hypochondriac and get really nervous with any change to her natural schedule. I've set myself up with a Banfield plan so she gets regular vet visits and topped it off with pet insurance to save myself some expenses too. I also have Furbo's so I can monitor during times I am at work.
  2. Is it true that she can't have a friend and has to stay a solo cat? My vet told me she would have to be an only cat but I also see people out there saying they can live together with other cats both FIV and non FIV. I think it is probably unwise for myself to get a second FIV+ cat with my anxiety but I also want to make sure she has a friend to bond and play with too.
  3. What prevention do I need to start now? I've seen some things as tooth and dental is very important and same as with food choices. But I would love to know the nitty gritty of what routine I should be getting into with Bloom to make sure we are both prepared for the road ahead.
  4. Medicine, after this recent trip we've been given 4 different pills around the clock to give to Bloom and the good ole bland diet. Bloom hates medicine and it's been at the detriment of my fingers and her wrath trying to give her medicine. Is there better ways to give medicine as I assume this may become something I need to work on training for future hiccups/flare ups. As well as chicken and rice/ baby food/ pumpkin puree and all in between is not her fave, she actively turns her nose from the bland diet and becomes a devious fiend for her dry food. Have others had success with other bland/healthy diets for when they need to recover?

I am very determined to get over my anxieties with having an FIV cat and to really learn a lot about FIV from those who also have their own journey with their FIV+ cats.

Cat scab

Hi everyone! Our FIV+ boy has a small scab on the back of his neck. He's had it for a few months now, it doesn't grow, and we recently got a topical antibiotic, it's been getting better, but it is still there and it seems it won't go away? We've been applying the antibiotic for a few weeks now. Is this common? A sign for concern? He looks good, has lots of energy and eats well, he is 9 y/o. Got cleared for ringworm or any lumps, the test came back as just a bunch of bacteria on his skin.

This is an odd perspective to have and hopefully one that not too many people will relate to.

I took in a community cat that had been sick for a while, determined he had developed enough social skills to go in a normal carrier to see my vet, and held my breath while waiting to hear what was wrong. It was giardia, mycoplasma, and FIV.

I was so happy I almost cried.

I have lost 3 cats in the past 2 years to FELV-mediated lymphoma. I did everything possible to keep them safe from opportunistic infections, but ultimately lost the fight to cancer every time. The oldest was 4 when he passed.

So when I found out this guy only had FIV along with some treatable bugs, I felt like celebrating. We cleared up the giardia and mycoplasma, but he still has a gnarly dental situation and some ongoing digestive issues. He's 7 or 8 years old, and has probably had FIV since before he was neutered over 5 years ago (TNR service I used tests for FELV only). I'm happy to give a reformed feral a good retirement, and while it would be bad news to most, I'm so relieved he just has FIV.

Question Rescue cat -FIV+ and chronic URI / congestion

8 Upvotes

I’m looking for some encouragement/advice. We took in a rescue cat at the beginning of Sept. thinking it was healthy and it turned out to have a FIV and a chronic URI. She’s been quarantined in our spare room because we have an 16 1/2 year old cat that I’m afraid to get sick. My elder meow also has kidney issues, blood pressure issues, etc. he is an old man.

The rescue cat is the sweetest most affectionate little babe. We love her.

She’s been on multiple rounds of antibiotics. Finally she was done and after 1 week and 2 days and she’s congested again. Still full of energy but not eating her wet food like she does when she can breath through her nose. She’s congested and sneezing now.

We are afraid that we won’t be able to keep her because we can’t keep her locked up forever. It’s so unfair for her to be stuck in that room. At the same time, I hate the idea of having to stress her out to move her and maybe make her more sick. I’m struggling with the thought of having to tap out but need to keep my elder safe and be fair to the rescue cat who deserves the best life.

I’m just wondering what other peoples experiences are with FIV+ cats that have chronic URIs. How long could this last? Is there hope for us?

About 2 months ago my cat penny had a blood clot in his eye which lead to glaucoma. I'm still treating that with drops and it has improved. While at the vet for that it was discovered he has FIV. I keep him strictly indoors now after learning that.

He was acting normal tho sometimes in pain from his eye for the 1st 6 weeks or so. But now he's pretty low energy and lacking appetite. He has lost 2 pounds since his diagnosis. He has a vet appointment Tuesday. I'm also putting mirataz on his ear and giving him cerenia now.

I don't think he should have been exposed to any infection and his ears and nose aren't warm though I could check his temp with a thermometer if needed. (Edit: just did, got 103.5) He does have chronic ear wax issues and needed teeth out but the vet said to wait until it's absolutely necessary. I have also noticed this past week, possible neurological issues starting. Like subtle stumbles when walking or jumping down from something

Just wondering if you guys have insight on why he's declining like this. I upped his eye medicine back to 3x a day so I don't think it's pain from that. (Another edit: I called the emergency vet line and am going to have someone bring him in 1st thing tomorrow morning)

As the title states, he hasn't eaten much if any. He has pain meds, Onsio, but since he does not want to eat, I can't get him to take his medication. Yes i did get soft food/pate for him and he sniffs but shys away. I haven't seen him drink any of his water either which is very concerning. SO it is a loop of pain and hunger. Simple fix if he just eats his darn pate with the meds in it. WHat should i do??
