Feline Infectious Peritonitis (FIP) Remedies

Last Modified on Jan 17, 2016

Home Treatments for FIP in Cats

Feline infectious peritonitis is a viral infection found in cats around the world in both domesticated and wild cats that attacks the cells of the intestinal wall, causing an intense inflammatory reaction. Cats carrying the virus are at risk for developing FIP, depending on the immune system; but the coronavirus that causes the disease is not highly contagious and is only truly virulent in the saliva and feces when a carrier cat has an outbreak.

Initial symptoms of FIP include sneezing, watery eyes, nasal discharge, and sometimes diarrhea. As the disease progresses a cat may lose its appetite, weight, lower energy and exhibit depression, fevers, and develop a rough coat. FIP has two forms: “dry” and “wet”. The dry form is more common and exhibits the symptoms above, but the wet form has a faster onset and is characterized by an accumulation of fluid in the abdomen. The fluid may cause a potbellied appearance and can interfere with your cat's breathing over time.

[YEA]  Black Spots: About 15 years ago, I had 2 cats (still have one) who endured the dry form of FIP. Being an immune system problem, one of the cats developed a number of tiny black spots under her chin. I used aloe vera gel that I applied topically and the fungus resolved within a week or so. Both cats recovered from the FIP but the Siamese lost her hearing. She lived to 16 yoa. The long-haired yellow cat is still living and is quite lively. She's about 17 years old. Both cats are/were on a raw food diet. Except for the time, early on, when they had FIP, neither has ever had fleas, ticks, or any parasite and they were outdoors in a protected area for much of that time. My yellow cat developed, first, a sebaceous cyst on her left shoulder where she received a rabies injection in 1994 (she's never had any more rabies shots since). I gently squeezed it and expressed a waxy substance and it disappeared for a number of years. It is back now and there is a rather large serous cyst below it as well. Am going to try the turmeric by adding it to her food. We just began using apple cider vinegar yesterday. I have a 2 year-old Siamese male as well. He received numerous multiple injections (just criminal) from the pinheads who sold him as a 4 month-old kitten. But, that's another story.

My cat have FIP dry form and at the same time she have neuron problem.She's taking medicine from vet as well (peridnisolone, b complex and also supplement pills).I tried to feed her with dilluted ACV but seem like she dislike the taste and refuse to drink it. Any advice on giving her ACV? Is it any side effect if I use those medications with ACV?

Hey Diana!

I am sorry to hear about your cat :(

Conventional treatments indicate your cat is a dead cat walking and it's only a matter of time before you have no choice but to PTS to end his suffering. Read up on the horror stories to prepare yourself for this battle:

Another good source of info on FIP:

Death sentence aside .....

This website has information posted by Irene de Villiers, B.Sc, D.I.Hom/D.Vet.Hom, who has effected cures of FIP cats; is very indepth and contraindicates the steroid your cat is currently taking - **read it**:

There are many homepathic remedies suggested, far too much information to post here.

Hey, Diana!

DOH - I sent too soon!

To dose your cat with ACV, try adding 2-3 tablespoons of the raw, unfiltered, "with the mother" ACV to 1 cup of purified water, then dip your cat's paw in the ACV water so its saturated and sopping wet. Chances are your cat will lick his paw to dry himself off.

I do not know if ACV is contra indicated with your cat's current medications; to be on the safe side dose the ACV 2 hours after you give him his meds or at least 2 hours before you give him his prescribed meds.

Dear Theresa,

I try my best not to give her PTS, as now I can see quite good improvement on her movement, the way she walk and eat, she also even can climbing up to her upstair level in her cage! For time being, I used to give her ACV (dillute with clean water and feed her by syringe) in the middle of the time of her meds.Means like she eat meds during morning and night.So, during evening I give her some dilluted ACV. Please pray for my cat to recover. Anyway tons of thanks for your advice. (^^, )

Diana, do consider the homeopathic remedies as outlined on the links below.

Some tried colloidal silver, some MMS, but none reported cures except the homeoathic vet.

And yes of course! Sending prayers for the recovery of your kitty!

Hello Diana and Theresa,

Hope to get quick response from both of you. My cat was recently diagnosed for FIP Wet Form. And I've been getting treatments from UPM, UVH (University Putra Malaysia, University Veterinary Hospitals). I've been trying to find Homeopathy treatment centre for cats in Malaysia, but failed to come across any. Was just wondering if anyone of you (Theresa, Diana or anyone) know any Homeopathy centre for pets. I've been getting homeopathy treatments for myself but only got to know there is for pets through this posting. And to Diana, may I know where do you go for treatments for your cat on FIP? Please help. Thank you in advance!

My thinking is that if you can get your personal homepath on board you will be able to utilize the tried and proven homeopathic remedies used by Irene de Villiers.

I have had my cat to the vet 3 times this week to have fluids drained out of his chest cavity. His blood work was normal and no temperature. He is breathing harder now then when he went in. He had been coughing for months off and on before he started breathing hard. One cat is sneezing a lot and the vet thinks she has asthma. Some of the other cats are coughing at times. How can I keep the fluids from filling up in the chest? Will organic vinegar work and how much should I give him? I gave a quarter of a eyedropper of aloe vera tonight. Don't know how much to give him. He is on AMOXICILLIN and another strong antibiotic for a few more days. It isn't working. I am in desperate need of help for him asap. Sincerely, Lorna

Hey Lorna!

Your post is under an FIP heading but it sounds as if your cat is suffering from congestive heart failure. There is no quick fix for CHF, however there are some drugs your vet can prescribe to help with the fluids. You have had your cat in to the vet 3 times - what does the vet say is the cause for the fluid build up?

For sure you can give all your cats the ACV - just dilute it so they are willing to drink it - that or dip their paws in it and have them lick it off that way.

My cat has fip I think. I have had his chest drained 4 times and the next might collapse his lungs. He is having trouble breathing. How did you get rid of the fip?
Replied by Alina

I am not sure that it is FIP. It is not very contagious, so if your other cats are developing the symptoms it can be not FIP. To check the cat for FIP your vet must to analyse the fluid drained from the cat.s chest. If it is bright yellow (like a straw), viscous, has a lot of albumin in it (and cat.s blood has the albumin/globulin ratio less than 0.4), AGP level more than 1500 -that would point to FIP.

You should show this of FIP to your vet to accurately diagnose if cat has FIP or not. And treat him then accordingly to the diagnosis. Otherwise it's quite useless...

[YEA]  My female cat was diagnosed with dry form FIP back in early Dec. 2014. She is still with us. She declined despite all the meds from the vet. I still give the Interferon. At about 5 months she had gone from 12 lbs down to 7. You could see her spine. I looked high and low for something to give her. I had decided to try Iron and vitamin D3. She has gone back up to just over 9 1/2 lbs and even when you pet her you do not feel her spine. She acts like nothing is wrong with her at all and I will continue with this. I have opted to give her gluten free canned food for breakfast and for dinner her normal canned friskies. I also keep dry gluten free mixed with her Kit and Kaboodle that she has always loved.

Hi Deborah! How were you able to get the Interferon? Everything I've read describes it as an experimental treatment. My vet told me there is no cure or treatment for FIP, just ways to slow it down a bit, like steroids. Any info would be much appreciated!
