This video is primarily for veterinary surgeons, vet students and vet nurses.

Patrick, a young domestic shorthair cat, suffered chronic diarrhoea and faecal incontinence for eight months from the day of his adoption from a shelter in Ireland. Feline diarrhoea can be caused by a number of parasites, bacteria, protozoa and viruses, but all were ruled out except for feline coronavirus, which was positive.

This video tracks Patrick’s faecal score from 7 (watery dysentery) to a normal faecal score of 2 using a veterinary faecal score chart (not the Bristol faecal chart for humans). The cat was cured after a seven day course of GS-441524 pills and he is still well five months later.

Chronic enteropathy, also called inflammatory bowel disease (IBD), is a condition with many possible causes in all species, including the cat. Feline coronavirus (FCoV) is such a ubiquitous virus that its presence is often overlooked when a diarrhoea panel reports a positive result: the aim of this video is to get veterinarians to take FCoV seriously as a cause of chronic enteritis because it can be treated fairly easily.

WHO IS DR ADDIE?
Diane Addie is an independent veterinary virologist, she was a Senior Lecturer at the University of Glasgow Veterinary School and Head of Diagnostic Virology. For over three decades her research has been devoted to feline coronavirus (FCoV), and her website, www.catvirus.com is mainly devoted to FCoV and FIP. She is a member of the European Advisory Board of Cat Disease, but the views expressed in this video are her own.

L-LYSINE SUPPLEMENTS SHOULD NOT BE GIVEN TO CATS, because L-lysine is antagonistic to L-arginine which is an essential amino acid for cats, meaning that they have to get L-arginine in their food: cats rapidly sicken without it. L-arginine is found in meat: cats are obligate carnivores. This video explains why dietary L-arginine is essential for the urea cycle to work in the cat (whereas humans can be vegans and our urea cycles still function). L-arginine is also essential for macrophage function.
Three key enzymes compete for available L-arginine: arginase-1 in the urea cycle, inducible nitric oxide synthase in M1 macrophages and arginase-2 in M2 macrophages. When L-arginine is in short supply it will preferentially go to the urea cycle rather than the immune system. Macrophages are key cells for immune function and are the target cell in feline infectious peritonitis (FIP) development.
Are cats with low plasma arginine more likely to develop FIP? I don’t know, but I suspect the answer will be yes. I do know that lowering their plasma arginine by using L-lysine will sabotage their ability to recover, and I suspect that using L-lysine in feline coronavirus (FCoV) infected cats will make them more likely to develop FIP.

For over three decades her research has been devoted to feline coronavirus (FCoV), and her website, www.catvirus.com is mainly devoted to FCoV and FIP. She is a member of the European Advisory Board of Cat Disease, but the views expressed in this video are her own.

Audience: veterinary surgeons, veterinary students and vet nurses.
Relapses are more likely to occur if you begin treating feline infectious peritonitis (FIP) with injections, rather than pills. Feline coronavirus, the virus that causes FIP, replicates in the intestines: first in the epithelium of the tips of the villi of the small intestine, and later in the ileum and colon. Pills get right to where the virus replicates in the intestines, stopping the virus dead in its tracks, whereas antiviral injections, such as GS-441524 or remdesivir, do not enter the gut well, so cats can still shed coronavirus in their faeces, even though they may appear to have recovered from FIP. Antiviral injections may appear to heal feline infectious peritonitis temporarily, but they predispose to a relapse, especially a neurological relapse if too low a dose of antiviral has permitted virus to persist in the brain.
Key messages:
1. do NOT use injections to treat FIP: use pills.
2. start treatment with a high dose of antiviral (exact dose will depend upon what you're using).

In this film for veterinary surgeons, I describe how antiviral drug resistance occurs in feline coronavirus infection: it is NOT due to early treatment, but instead it is due to treating with too low a dose of antiviral drug, and to using injections instead of pills. Pills get right to where the virus replicates: in the intestines, whereas injections may appear to heal feline infectious peritonitis temporarily, they predispose to a relapse, especially a neurological relapse if a low dose has permitted virus to persist in the brain.
Key messages:

I am extremely indebted to Roger Coleman, CEO of Applaws cat food, for informing me that Applaws chicken and pumpkin cans can stop diarrhoea.

An inexpensive way of checking if your feline infectious peritonitis (FIP) treatment is on track or not is by regularly weighing your cat: once a week, or once a day. On average, a recovering cat will gain about 25g (1 ounce) of weight per day while on Mutian pills, then about half that when you stop Mutian pills and go onto 100,000 units of Virbagen Omega feline interferon by mouth. Weighing the cat does not replace the necessity for regular blood test monitoring, but can be useful for quickly detecting when there is a secondary problem, for example furball. Some people use baby scales, others use their kitchen scales.

Felocell FIP is an intranasal vaccine against feline infectious peritonitis: it contains a temperature-sensitive type II feline coronavirus (FCoV) strain which can replicate in the cooler nares of the cat, but not at the higher temperature of the body.
In this video, I am going to answer questions frequently asked about the FIP vaccine:
• does the vaccine work?
• could the FIP vaccine itself cause FIP?
• does the FIP vaccine cause antibody enhanced disease (ADE)?
An independent, blinded, placebo-controlled field study by Swiss veterinarians at the University of Zurich showed that the vaccine was both safe and efficacious.

A cure for feline infectious peritonitis – FIP – has recently been found, but currently (2019) there is no veterinary preparation available. It costs thousands to treat a single cat, and the cat has to endure 12 weeks of painful injections which can cause weeping sores on the skin.
My aim is to eradicate feline coronavirus, the virus that causes FIP.
- SUMMARY OF KEY MESSAGES -
1. THE SINGLE MOST EFFECTIVE WAY TO PREVENT FIP IS TO PREVENT A KITTEN OR CAT FROM EVER BECOMING INFECTED WITH FELINE CORONAVIRUS (FCOV), THE VIRUS WHICH CAUSES FIP.
2. The virus is shed in the faeces. Cats become infected with FCoV by sharing a litter tray with an infected cat, or via contaminated cat litter dust particles.
3. There is no need to invent an anti-viral cat litter: cat litters which inhibit FCoV already exist.
4. Dr Elsey Cat Attract was the best cat litter for reducing FCoV transmission and EverClean Clumping was also good.
5. Unfortunately, even the best cat litter cannot wholly prevent FCoV transmission, but it can reduce virus load in a household or shelter.
6. The best way to prevent FCoV infection is still to allow cats outdoors to toilet.

- HUGE THANKS -
I am immensely grateful to my co-authors on this study: Kirsty Maitland did the in vitro cell culture work. Huge thanks to Lene Houe of the Felismir Katteklinik in Denmark who took all the rectal swabs – sometimes as many as 50 in a month! I am very grateful to the guardians of the households for persevering with testing their cats. I thank Prof. Nicola Decaro at the University of Bari who quantified the virus on rectal swabs.
I am thankful to Matt Golder for help with the in vitro study and to the late Prof. Marian Horzinek for extremely useful discussions on this project. I also want to sincerely thank an anonymous reviewer of the JFMS paper, who was absolutely wonderful in fine tuning the paper, and checking the numbers.
Huge thanks to donors to the Angelica Fund (www.catvirus.com) and Orion Foundation for funding my research. Much gratitude to Michael Riley (Better By Nature); Kruuse (Denmark) and Gina Zaro of Dr Elsey Cat Litter for funding FCoV RT-q PCR testing and supplying some of the cat litter for the in vivo part of this study. I thank Roger Coleman (MPM products) and Alan O’Dell (Cat Country) for supplying some of the cat litters used in the in vitro study. I am grateful to Pfizer for funding the salary of Kirsty Maitland. I thank Maria Bonino for funding testing of two households which used World’s Best Litter that could not be used in the study (due to lack of virus transmission), via a donation in memory of her beloved cat, Luca, who died of FIP.
None of the sources of funding had any input into the design of this study, the writing of the JF

In this video I’ll show you how to make a cup of soup containing 19 grams of #protein and only 139kcals.
— RECIPE —
1. Put half a teaspoon of a good-tasting stock powder or a stock cube into a ½ pint / 250ml mug. My favourite is #Marigold Vegan Stock powder.
2. Add 1 level tablespoon of #vegan protein powder: I find the best is Power Health Soy Protein isolate: other makes have a horrible taste, or the powder forms into clumps like chewing gum.
3. Pour in your favourite unflavoured plant-based milk: I use soya milk to get the maximum amount of protein. In my book, Protein Rich Soup, there is a table of the amount of protein in each plant milk.
4. Stir the powders into the milk and microwave for 1 to 2 minutes – depending on how powerful your microwave is. Now you have your high protein vegan keto cup of soup to enjoy.
Ring the changes with additions such as baby leaf spinach, crumbled nori, fresh herbs, to obtain more nutrients and vary the taste.
Swap out one of your meat meals for a plant-based meal … for the sake of the animals, and for your own sake, for example to avoid strokes and heart attacks.
For more protein rich soup ideas, please see my book Protein Rich Soup: www.amazon.com/Protein-Rich-Soup-Where-Your/dp/197580175X/ref=sr_1_2?s

DOES TOMMY HAVE DRY FIP? Part 5.
In this educational video for veterinary surgeons, we go through the list of differential diagnoses of feline uveitis established in Part 3 of this video series and discussion the rationale for which tests to request at a reference laboratory.
The final diagnosis is reached and we find out what happened to Tommy.
This video counts for 10 minutes of veterinary continuing education.
The video ends with a tribute to Wicks, a very special cat.

Feline infectious peritonitis (FIP) is a lethal infection of cats and getting the diagnosis correct is vital for your patient. In this video I examine the cat’s history to determine whether or not he had the opportunity to become infected with feline coronavirus (FCoV). Without spending a penny in tests, we will already come to a conclusion about the chances that this cat has FIP and the video contains an important clue to his diagnosis.

Feline Infectious Peritonitis
Lessons from Luca: Use the right veterinary laboratory tests

This is a film for veterinary professionals. Luca was a cat with histopathologically confirmed feline infectious peritonitis (FIP). The purpose of this educational film was to emphasise the importance of sensitivity of a feline coronavirus (FCoV) antibody test when ruling out FIP as a diagnosis. As a consequence of using an insensitive test from Antech Diagnostics, Luca was dragged round a series of veterinarians in search of a diagnosis; he was subjected to numerous blood samples and his guardian suffered the distress of desperately trying to help her deteriorating cat, not to mention that she ran up a bill in four figures during the process.
Key message: sensitivity is EXTREMELY IMPORTANT when using a FCoV antibody test to rule out FIP
Key message: send the CORRECT sample for the test required:
• blood for FCoV antibody test, not effusion
• effusion for FCoV RT-PCR, not blood
The second mistake Luca’s veterinary surgeon made was sending blood for FCoV RT-PCR: the result was negative. Most cats with FIP will not have FCoV RNA in their blood; a fine needle aspirate of a lesion should have been sent in Luca’s case, since he had non-effusive FIP. In effusive FIP cases, the effusion should be sent for FCoV RT-PCR testing.

The transcript of the narrative and details of references / further reading can be found in the catvirus.com veterinary newsletter at http://www.catvirus.com/downloads/LucaVetLab.html
