Mission statement:

I want to eradicate feline coronavirus (FCoV) and feline infectious peritonitis (FIP).

If you would like to support ending FIP, please donate to me and my research.

People often think that I am searching for a cure for feline infectious peritonitis (FIP), but while a cure interests me, I am far more concerned about saving cats from becoming sick in the first place.  I want to eradicate feline coronavirus, to prevent cats from ever becoming ill with FIP.   If you share this goal and would like to support me and my research, (which does NOT involve deliberately infecting laboratory cats) please enrol for one of the subscription programs below.  Details of how to make a donation, without joining a support group, can be found at the foot of the page.

Memorial list of donors and the cats whose memories they honoured by making a donation to FIP research: this is where your cat's name is if you have donated, please scroll to the end of the table or do a search for your, or your cat's, name

Chapo, chat norvégien né le 12 mai 2007, décédé le 18 mars 2008 à l'âge de 10 mois.

Avec tous ceux qui t'ont aimé, je gardais l'espoir que tu guérisses. Toi et moi nous nous sommes battus contre cette maladie qui emporte les jeunes chats, sans pitié. Mais elle a finalement eu raison de ta vie.
Tu t'es éteint chez le vétérinaire et je garde le souvenir d'un chat affectueux et tendre, le rythme à travers l'oreiller de ton petit coeur battant, quand tu dormais à côté de moi, paisible et apaisant.
Chapo mon petit ange, tu emportes avec toi tout l'amour que l'on t'a donné.
Tu m'as épargné la terrible décision, pourtant, je regretterai toujours de n'avoir pu te serrer dans mes bras lorsque tu t'es endormi....

Research Funding

Funding for FCoV/FIP research is very difficult to find and I am immensely grateful to those generous individuals who have given what they can for research.

I refuse to experiment on cats, so all my FIP research has been done on naturally infected cats: I am immensely grateful to the cats themselves, to their generous guardians who have permitted samples to be sent to our laboratory, and to their veterinary surgeons for taking the time and trouble to prepare and mail samples.  


What have I done with your donations and grants?

For three decades I’ve studied feline infectious peritonitis (FIP) and come to the conclusion that the search for a cure is like closing the door after the horse has bolted: most FIP cats are just too sick to be fixed, plus some cats go through torture in the attempt to reach a diagnosis.  How about we stop the cat getting infected in the first place? (You can read my blog on this subject on Steemit: please vote it up.) I have demonstrated that quarantine and FCoV antibody testing can prevent FCoV being introduced into a group of cats (Addie et al, 2012). The next step was to find out which FCoV antibody tests were adequately sensitive to enable effective screening: see my paper Addie et al, 2015. The following projects are towards this goal.

Cat litter to reduce FCoV infection: funding from this website enabled a comparison of cat litters for anti-coronavirus activity, I found that commercially available cat litters had widely differing abilities to neutralise coronavirus in the laboratory - but would they make any difference in the field? Choosing a litter which had coronavirus activity and subjectively was assessed to track less than most litters, a preliminary study has recently been completed and a study in a cat shelter is about to begin to assess whether the litter can affect virus transmission in a real life situation.

Carrier cats: people whose cats were identified as healthy lifelong carriers kindly allowed me to post-mortem the cats when they died. I have been looking in the tissues of these cats to locate the virus, this work is ongoing. I am grateful to Fermin Simons of the University of Utrecht for his help and advice in this. Currently we are identifying healthy shedder cats and attempting to help them eliminate the virus.

FCoV resistant cats: the Orion Foundation funded preliminary work looking at the genes which govern immunity in the cat, this pilot study was published in the April edition of JFMS 2004. On this occasion, no marker was found, though interesting differences in the numbers of these genes was found in different cat breeds.

Equipment - donations from the Angelica Trust have supplied a freezer and microscope, amongst other items, specifically for FIP research.

Donations for FIP research will be / were used for the following:

To buy the chemicals needed to do the experiments to discover more about natural feline coronavirus infection and FIP.

Donations so far have enabled the purchase of a PCR machine, microscope (thank you Loretta!) and -80oC freezer (thank you Steve!)

To follow naturally infected cats and, with the help of their humans, eliminate this virus from the cats. This will involve taking samples of faeces, saliva and occasionally blood.

To perform post mortems on naturally infected cats who have partaken of surveys or treatment trials and to then cremate their bodies and return the ashes to the people who loved them.

To do a properly controlled international study of different FIP treatment protocols, (this will cost several thousand pounds and I’d need to employ a veterinary PhD student to help with the work).

We assessed available FCoV antibody tests so that the best could be identified for use in eradicating FCoV, and therefore FIP and to discourage the use of poor FCoV antibody tests. The results of this study were published in JFMS in 2015 and can be found on the FCoV antibody page of this website.

To continue producing educational material to aid the eradication of FCoV, and therefore FIP.

Please note my research involves only naturally infected cats, not experimental cats or experiments on any other kind of animals.

Research papers published so far which acknowledge funding from Angelica Trust Fund:

A big thank you to those who have contributed to FIP research!

I would like to dedicate this website with gratitude to the many people and cats who volunteered to be part of my research surveys.  I thank the many grant awarding bodies (see below) and individuals for funding my research in the past and Su Startin and Loretta Bartolucci who, having already enabled the purchase of a splendid microscope, are currently raising much-needed funds for another freezer! Big thanks for recent superb donation to everybody on the Cat-lendar team: Ilaria Isaia for having the ingenious idea; Lorena Migliaccio who did the graphics; Cristina Cattania for taking care of the orders and to Barbara Fruschi who promoted the sales. And another huge thank you goes to Bengals Illustrated for a whopping donation summer 2009.

Thank you to the Devon Rex Breed Club of America for a big donation in April 2006 and the Siamese and Oriental Online Club for raising money in June 2006! Thank you Susanne, for your fundraising website, FIP Support, and the fantastic donations you made in 2005 and 2006!

I am grateful to the Wellcome Trust, Cats Protection, the Robert Daubney Fund of the Royal College of Veterinary Surgeons, the Clinical Studies Trust Fund, the Feline Virus Unit for funding my PhD and previous studies of naturally-occurring feline coronavirus infection and FIP. I thank the Morris Animal Foundation for funding a project to attempt to identify unique markers of coronavirus infected cells. I am especially grateful to Pfizer for a generous donation of $25,000 which enabled me to take on an assistant part-time for one year (2004). I am grateful to the Winn Foundation for a grant which allowed 5 months of research into carrier cats in 2003. I am also extremely grateful to the Orion Foundation for moral support (thank you Mel Amundson and Pat Klein), and for a huge donation of almost $13,000 in 2003! Thank you Orion! Many thanks also to individuals and the Scottish, Northern Counties and Yorkshire Cat Clubs who made donations in 2005 and 2003. Thank you to all donors for your generosity. Thank you to Lorraine Twyman and the Norsk Skogkattring for setting up an internet auction (see the lovely certificate they sent). Thank you Dorothy, for your wonderful contribution of getting people to sponsor you during Lent. And last but not least - thank you to the anonymous donors - you know who you are - who have been so very generous.

Join the EndFIP Facebook group

Do you want to play an active role in ensuring that no cat ever again develops FIP? Then join the End FIP group.

The End FIP group supports work and research towards eradicating FCoV and FIP by people who do NOT want their funds to be used for experimentally infecting cats in the laboratory. This group is limited to 100 members: its purpose is to support Dr Addie personally (i.e. to provide a salary to free up her time to dedicate to FIP research); to fund her research and to provide a service to the members themselves.  One way of dealing with the overwhelming amount of emails Dr Addie receives is to have a subscription service: members of this group will be more likely to have their queries answered personally than will non-members, especially if the group moderator flags their case to me.  Imagine if your cat was diagnosed with FIP and you wish you’d taken out this subscription?

  • for those who have paid for a year in advance, provided their veterinary surgeons give consent, up to 3 sets of laboratory results / clinical history will be analysed to establish whether or not a cat truly has FIP (more analysis interpretation may be given depending on circumstance)
  • for those who have paid for a year in advance, provided their veterinary surgeons give consent, Dr Addie will work alongside the veterinary surgeons to help determine the best course of treatment for cats with FIP, analysing laboratory results, up to a maximum of 8 emails in the year
  • membership of the exclusive End FIP Facebook group (https://www.facebook.com/groups/1623039167989625/) which Dr Addie will attend live on, from time to time
  • veterinary surgeon and technician members will have an option of discounted CE / CPD
  • email newsletters
  • members of this group will be the first to know when any clinical trials open up that require volunteers
  • priority placement on the reserve list for the inner circle on a first come, first served basis
  • members will be able to transfer their membership to other people, if they wish to do so
  • members get to influence Dr Addie’s next work output by voting on what they would like to see her produce next: choosing between scientific paper writing; YouTube video; website page update; veterinary surgeon education, etc.etc.
  • members will receive a relevant free  e-book as and when they are written

These are the activities of Dr Addie that you will be supporting:

  • Scientific research to forward her FCoV/FIP eradication dream
  • Providing materials to educate veterinarians
  • Providing materials to educate the public
  • Updating the website and keeping it and the video channels advertisement free
  • Making new educational YouTube videos
  • Answering queries from veterinary surgeons
