- Chewing the tree or its lighting cables. Real dangers. Whether you have a real or an imitation tree, put up a barrier around it and keep those electric cables where your bunnies cannot get to them
- Holly and mistletoe are both very toxic. Make sure your beloved pets can’t get to either. If you have them, keep them both well away from rabbit accessible areas
- Wrapping paper and the gifts themselves. Nobody wants a chewed present and of course ingesting that paper with its inks and possibly sometimes polymers too is very dangerous for rabbits, so keep gifts out of reach of bunnies
- Eating too much of the wrong thing. We all eat some treats in the festive season, probably more than we should, but be careful not to let your rabbits get to anything that might be toxic to them or too much of what they might like. Chocolate is highly toxic to dogs and in fact is bad for most species including us. For rabbits, the sugars may well be the biggest problem, so as with other treats, keep them away from your rabbits and if you have appropriate treats for them – low carbs, no egg, no dairy – remember, they are still just that, treats, and should only be given in very small amounts. You don’t want to be taking your beloved rabbits to the emergency vet on Christmas afternoon!
- Company, hustle and bustle – Christmas and New Year are times for families, visitors, people who generally wouldn’t be in contact with your rabbits, and likely not in large numbers. It’s often noisy as well. Remember this can be very confusing and sometimes frightening for your rabbits. They are prey animals, used to you and your immediate family so make a visitor-free zone where your rabbits can feel safe and can keep away from noise and bustle, won’t be handled inappropriately and won’t be fed the wrong things….and cannot escape out of your door when people are coming and going.
Welcome to another Campaign Update, keeping you informed of our constant fight to make things better for bunnies.
Richard’s new qualification
As if Richard Saunders was not already fantastic enough, he has added another qualification to his name. He now has the European College of Zoological Medicine, Diploma Specialist in Zoo Health Management to add to his accolades. This gives him more letters after his name, and he is now on the Scientific Committee for EBVS.
RVHD2 HIPRA webinar
Richard has recorded a webinar with HIPRA, who are the manufacturer of Eravac, on the ever-popular subject of RVHD2. As soon as it is available we will share the link to it on social media, so keep your eyes peeled.
We now have over 110 rabbit friendly vets on the rabbit friendly vet list! This is free to access to anyone via our website. Due to huge demand we have had to close applications for the rest of 2018, because we have such a backlog to get through, but we will be opening it up again in the New Year. This is great news as it shows that practices are keen to be considered rabbit savvy, and realise the rising status of rabbits in the UK. Anyone who is looking for a rabbit savvy vet can find our list here: https://rabbitwelfare.co.uk/rabbit-care-advice/rabbit-friendly-vets/rabbit-friendly-vet-list/
Save the dates
We are finalising the conference dates for 2019 so you might like to save these dates:
1st June– Non clinical day (owners, rescue workers) in Birmingham.
1st June– Clinical͚Rabbit Essentials͛ day, in Birmingham. This is for vets and vet nurses. It is lecture based and will cover subjects that we think are essential for every small animal practice.
22nd June– Advanced Rabbit Practice, at The Royal Veterinary College, Hawkshead. Lecture based, but covering more advanced rabbit care and investigation using the fantastic team at the RVC.
23rd June– Rabbit Interactive Roadshow – 2 x 3-hour workshops covering dentistry and airway management, also at the RVC, with the fabulous Craig Hunt. Small group so be sure to book early.
1st December– Rabbit Interactive Roadshow – 2 x 3-hour workshops covering dentistry and airway management, in Newcastle Upon Tyne, using the awesome Kevin Eatwell. Small group so book early to grab a place.
Full details will follow shortly. Please keep an eye on our website, and social media, or sign up to our First Alert service. You will be able to book via our shop website shortly.
Consultations and new legislation
Despite the amount of work and debate that Brexit has generated, there is still some progress with animal welfare legislation. There have been consultations for the UK for animal sentience and for Scotland with regards to breeding and licencing. This is obviously an area we are very keen on, given our Capone Campaign work, and something we can respond to with a lot of confidence. There have also been consultations on licencing of pet shops, riding schools etc., and on the 1st October 2018 the English government launched new regulations for the sale of puppies in the UK. This is great news, and we will be looking into the possibility of this legislation applying to rabbits also.
BBC Radio Shropshire – The rabbit and guinea pig debate
BBC Radio Shropshire phoned the helpline in October after an on air discussion between listeners who were discussing keeping rabbits and guinea pigs together, which caused some contention. We were invited on the next day to put the record straight, which is exactly what Richard did!
For interest, this is our official stance:
We are often asked about keeping rabbits and guinea pigs together. This is not advisable for the following reasons: ͞Bordetella bronchiseptica is a bacterial infection of the upper respiratory tract of a number of species, including dogs, rabbits and guinea pigs, related to B pertussis, which causes whooping cough in humans. It is often described as commensal in rabbits (i.e. found in this species without causing harm), however, it can be a primary disease-causing organism, and can complicate other infections such as Pasteurella. It can, though, be fatal in guinea pigs, and so keeping them in the same airspace as rabbits is not advised.
͞Rabbits and guinea pigs have different dietary requirements, particularly guinea pigs’ need for Vitamin C. ͞Rabbits and guinea pigs are not the same species, and cannot respond appropriately to one another’s behaviours. This may result in inadequate social behaviours, up to and including severe bullying. ͞
The main reason these species used to be kept together was for companionship without the risk of pregnancy. With improvements in anaesthetic safety and more widespread neutering of both species, this is less of a problem now. Whilst we would not recommend putting them together in the first place in this day and age, we would not advocate splitting up a stable sole rabbit:sole guinea pig pairing͟.
New vaccination poster
We are still hearing of owners who do not know about RVHD2 and the need for a second vaccine. Feedback suggested that our vaccination poster did not get the message across so we have a new vaccination poster which we hope will be more effective. If you are on social media please share. You can find it on our own social media pages and website. Just to clarify, this is our advice on vaccinations: ͞You will need to give your rabbits two vaccines every year to protect them. The most common are Nobivac (protects against myxomatosis and RVHD1) and Filavac (protects against RVHD1&2), or Eravac (protects against RVHD2)͟.
A full size version of the poster is on our Campaign page, under Resources
Latest on RVHD2
In addition to the confusion over the vaccines there seem to be rumours surfacing about more diseases. Just to put the record straight we have released this statement:
͞”Here at the RWAF we are aware of 3 significant fatal viral diseases of rabbits in the UK. ͞
Myxomatosis (covered by the vaccine Nobivac Myxo-RHD); Rabbit Viral Haemorrhagic Disease 1 (covered by Nobivac Myxo-RHD), and Rabbit Viral Haemorrhagic Disease 2 (covered by the vaccines Filavac KC and V, or Eravac).
͞We are not aware of any further versions of RVHD present in the UK, although the variant K5 has been discovered in Asia and Australasia. ͞
We are not aware of any viral infections that are acutely fatal to rabbits and rodents recently arriving in the UK. ͞
If anyone has documentary evidence of any exotic diseases arriving in the UK in future please inform us and the Animal and Plant Health Agency (APHA)͟.
Myxomatosis in hares
Just as we were going to press there was an article in the news about a hare being diagnosed with myxomatosis in the UK.
Here at the RWAF we have been asked, over the past week or so, about myxomatosis in native wild brown hares in the UK. It’s important to be aware that this information is subject to change as the investigating continues, but is correct at time of posting.
Sporadic cases have been reported in the past, of suspected or confirmed myxomatosis in hares, including one which was written up in the veterinary press in 2014. However, this appears to be different in that multiple cases, from a wide geographical spread, are being reported to Dr Diana Bell, University of East Anglia and, whilst some have obvious external symptoms of myxomatosis, other dead hares look fine/in good condition or are seen dying with unusual neurological symptoms including an inability to move and seizures. A number of possible causes are being explored, including a change in virulence of myxomatosis virus, infection with Rabbit Viral Haemorrhagic Disease 2 (RVHD2), or European Brown Hare Syndrome, individually or as co-infections, and it’s possible that other factors are involved.
What would really help the ongoing study into the large scale deaths of this iconic species would be for any members of the public finding a dead or ill hare to contact Dr Bell on: email@example.com. Please try and keep the body refrigerated whilst contacting Diana to arrange for a full post-mortem analysis.
Filming for RWAF YouTube channel
We are aware that our YouTube channel is in need of more content so we have recently spent the day with the lovely people at Vets4Pets Emmerson Green, Bristol, to film standard procedures and best practice. We hope that this will be accessible and useful to a wide range of people. Huge thanks to Sylvie Bolioli for giving up her time to do this
for us. We hope to have a lot of content for vets and owners in 2019. Again, watch this space for an update.
New RWAF Team member!
We are excited to announce the newest member of the RWAF Team – please welcome baby Eden. Emma (Boyd) gave birth to gorgeous little Eden on 15th September. It will be no surprise to read that Eden is already a rabbit fan and has a good collection of rabbit themed clothes and toys. Emma is on maternity leave until the New Year but she will soon be back in the swing of things and working alongside Rae to organise the CPD for 2019. If Eden is anything like her amazing mum then animal welfare is going to have a fantastic new advocate.
Please everybody share this poster and message in your emails and on social media, and on any rabbit or pet group you might be on.
Rabbits need vaccination every year to protect them against RVHD2 as well as against Myxomatosis and RVHD1. Unfortunately that can’t be given in one jab. There are two. For Myxi/RVHD1 they need the Nobivac combined jab and then for RVHD2 there is a choice of either Filavac or Eravac. There should be at least 2 weeks between the jabs.
The poster was updated this week and can be downloaded here https://rabbitwelfare.co.uk/campaigns/resources/
We are actually finding that by sharing to general pet groups we are getting the message to new people who weren’t aware.
**RABBIT OWNERS NEED TO KNOW, ALL THESE DISEASES ARE DEADLY**

There are two strains of RVHD, known as RVHD1 and RVHD2. Both strains are lethal and you must vaccinate to protect your rabbits. RVHD2 has been in the UK since 2013 and over time appears to be overtaking classic RVHD as the primary strain.
RVHD vaccines are very effective. Your rabbits can currently be protected against RHD1 using the Nobivac Myxomatosis-RHD vaccine with a booster every 12 months. Both strains of RVHD are covered by vaccination any time from ten weeks (Filavac) or RHD2 can be prevented from 30 days (Eravac) of age. The separate RVHD2 vaccine is given every 6-12 months. You should consult your vet for the best combination currently available for your rabbit(s).
It’s very important to clean and disinfect anything that may be carrying the viruses, including water bottles, bowls, bedding and housing. This means that boarding and rescue rabbits, even with up to date vaccinations, may potentially be a risk, and establishments should take suitable precautions, as should vets who may have infected rabbits brought to them for treatment. Anything that has been touched by an unknown rabbit should be thoroughly cleaned and treated with virucidal agents. In high risk situations foot covers or foot dips may be wise measures.
If you are about to obtain a young rabbit that hasn’t yet been vaccinated:
- Follow the advice given in the vaccinations section
- Don’t use second-hand hutches or equipment without finding out what happened to the previous occupant.
FAQ on Rabbit Viral Haemorrhagic Disease 1 and 2 Background:
For background, whilst the “classic” RVHD has been present in the UK for decades, variant RHVD (also known as RHVD2 or RHDV variant) was first noted in 2010 in France, and has subsequently been identified in the UK (OIE Technical Disease Cards, updated July 2015; Abrantes et al, 2012; Dalton et al, 2012; Westcott and Choudry, 2014). This virus has some differences from the classic RVHD. In particularly it may affect rabbits of any age, as opposed to RVHD1, which is rarely if ever seen in rabbits under 8-10 weeks of age.
It has also been reported that the variant gives rise to lower mortalities than classical RVHD, this is not necessarily borne out by reports (Abrantes et al, 2013), and this may be thought to be due to be the case due to its phylogenetic placement alongside non-pathogenic strains.
Mortality may vary from collection to collection, and possibly from breed to breed. The only vaccine for rabbits initially available with a UK License was Nobivac Myxo-RHD (MSD Animal Health), which was made available in 2012. Not long after that, the other 3 vaccines against RHVD on the UK market ceased to be available.
This vaccine does not appear to offer protection against RVHD2, and neither do the previous vaccine brands available in the UK. However, RHD1 and Myxo remained the most significant health threats which could be vaccinated against, and so coverage with this product remains a priority. Work from Italy and France, however, suggests that, with our reservoir of wild rabbits, we can expect to see RHD2 starting to predominate over RHD1 in the next 5 years or so.
Previously there were three vaccines (Filavac VHD K C+V, Cunivak RHD and Cunipravac RHD-2 Variant) that initially had a Special Import or Special Treatment Certificate from the Veterinary Medicines Directorate, on the basis of a clear need to do so given the current disease status. That need now having been firmly established, Filavac VHD K C+V, and Eravac VHD are now licensed. Practices should check availability of these products directly with their wholesalers. Owners should check with their practices which vaccines they hold, and what the protocol for vaccinating rabbits is at the practice in question.
Stocks are sometimes very variable, and practices are advised to contact wholesalers directly for information on stock availability. I would still be interested in any other practitioners findings regarding reports of suspected or confirmed RHD1 and 2.
Is vaccination necessary?
This will obviously involve a risk assessment of the individual rabbit(s), but the wide geographical range of the disease, and the reported losses of several hundred rabbits throughout the UK, as well as molecular testing confirmation of cause of death in many sampled, suggests that vaccination is strongly advisable.
Moredun Institute has advised RWAF that cases have been confirmed throughout the UK, so you cannot assume you are in a ‘safe’ area. Additionally we believe that RVHD2 will be significantly under reported. Because RHD2 doesn’t always look like classic RHD1, a rabbit could be taken into hospital looking ill, but nobody would necessarily think to treat that potentially infectious case for RHD2
Do existing RHD1 vaccines work? Because the mortality rate is lower with RHD2, any test using a small number of rabbits could easily show protection just because none of them were going to die anyway. There is some anecdotal evidence that RHD1 vaccines have some short term effect, but nothing peer reviewed. Le Gall-Recule (2013) showed that cross immunity between RHD1 and 2 was, at best, partial.
Do RHD2 vaccines work? Le Minor et al (2013) showed that Filavac produced good immunity (full protection) against RHD2 in challenge studies. (15èmes Journées de la Recherche Cunicole, 19-20 novembre 2013, Le Mans, France)
How will you get it from your vet?
Please only go through your vets, rather than contacting wholesalers directly.
What dose regime is suggested?
Standard advice with immunological products not licensed for simultaneous administration is to space them out by at least 2 weeks, and this is the regime we advise with both vaccines.
The duration of immunity for Filavac has been established at at least 12 months, in laboratory conditions in healthy rabbits. The manufacturer’s advice is to administer a single dose of the vaccine, followed by annual boosters in low risk situations, and 6 monthly in the case of breeding does at high risk. In the UK, I would suggest that high risk situations include rescue centres and breeders, unless they have a strict quarantine policy, and those rabbits which have greater contact with wild rabbits, as well as any geographical location where cases have been reported recently. All other rabbits are likely to fall into the lower risk category, requiring annual re-vaccination. The duration of immunity has not been confirmed in the case of Eravac, but this is expected to be updated shortly.
What does the vaccine cost?
Here at the RWAF we are not able to monitor or affect the prices charged by veterinary practices. It’s worth pointing out that the price of the vaccine may vary widely between practices due to pricing structures, and due to the caseload of rabbits that they see. If they are able to make use of larger vaccine vials, the cost may be shared across more rabbits and reduced, but this is not often possible, as it requires enough rabbits to be seen in a 2 hour window during which the vial may be used.
What if I buried my pet rabbit and now wonder if it was RVHD 2, will the ground be infected and a risk to my other rabbits? (How should bodies be disposed of?)
There is not enough information out there to know the correct answer to this. We know it can live for 200 days in ideal conditions, so there is in theory a potential risk but we are speculating here. The best way to dispose of the body of any rabbit that died a sudden or unexplained death is to ask your vet to get it cremated for you. Double wrap them in plastic, and disinfect the outside, before taking to your vet, to reduce the risk of disease spread.
Once rabbits have recovered from RVHD2 do they still carry it? Do they still shed? Can I bond to another rabbit safely without risking them?
There is not enough information known about RVHD2 to know the correct answer to this with any certainty. In theory they should be safe to bond after 200 days, in practice it may be safe sooner than this, but we really don’t know.
Can you recommend a cleaning protocol?
90% of any disinfection is cleaning, that is the most important aspect. After thorough cleaning of the area to remove any scale or residue, use Ark-Klens , which is a benzalkonium chloride disinfectant and as such it should be effective against EC and myxi, to routinely disinfect the housing. Periodically use Virkon (as an inorganic peroxygen compound) to kill any other viruses. Anigene HLD4V has been confirmed as effective against RVHD2 at a dilution of 1:50. It is important that the correct dilution is used”. Note: Other benzalkonium chloride disinfectants and inorganic peroxygen compounds may be available, in addition to those named above.
Other than vaccination can I prevent my rabbit getting RHD? Will they get it from hay?
They are very unlikely to get RHD (1 or 2) or Myxomatosis from hay or barn dried grass. Risk / benefit analysis would be in the favour of feeding these foods. Foraged foods may potentially carry RVHD. Try to obtain plants from areas out of the reach of wild rabbits, and do not collect forage from areas of known wild rabbit RVHD infection. Biosecurity advice was given in the webinar (link above) but summarised here: Use foot dips or change footwear between going outside, especially into areas frequented by wild rabbits Quarantine new animals, feed them last, use new equipment such as bottles / bowls for them. Barrier nurse any suspicious cases Try to exclude wild rabbits and unless they can be excluded from the garden consider stopping the practice of moving pens around the garden and even consider a double fence round rabbit runs.
What are the risks of “over-vaccination” and vaccine ingredients?
Vaccinating with an RHD 1 and 2 vaccine (Filavac), 1-2 times per year, on top of an existing RVHD1 and Myxomatosis vaccine (Nobivac), obviously increases the vaccine frequency and amount given to each rabbit. This is not perfect, but the alternative is missing out one of these vaccines, and the risk of “over-vaccination” is considered lower than the risk of insufficient protection. Filavac is an inactivated, adjuvanted vaccine, and so cannot lead to clinical RVHD in the animal. Eravac covers only RHD2, and so there is less concern about “over-vaccination” with this product. Concerns are often raised about vaccine ingredients (adjuvants and excipients) such as aluminium hydroxide and sodium metabisulphite. This is too large a topic to discuss here, but, without dismissing these concerns out of hand, and after weighing the risks against the benefits, vaccination has a strongly net positive benefit against the diseases discussed here. There are known vaccine side effects discussed in the data sheets for these vaccines. They are usually limited to small local transient skin reactions, and transient mild lethargy. Oil based vaccines such as Eravac carry a known risk of skin and subcutaneous tissue damage, and great care must be taken to ensure no vaccine enters the intradermal route, to minimise this risk, as well as taking care not to accidentally self-inject. The frequency of vaccination, and a risk:benefit analysis for each individual, should be discussed between client and veterinary surgeon before deciding on an appropriate regime and vaccination plan. There is a risk to any animal (or person) to having any vaccination, which is why animals (or people) should only be vaccinated if they are healthy. For further general details on companion animals, the BSAVA and WSAVA vaccine guidelines should be consulted. Note that under their definitions, in the UK and mainland Europe, RHD2 would be considered a “core” vaccination.
https://www.bsava.com/Resources/Positionstatements/Vaccination.aspx http://www.wsava.org/guidelines/vaccination-guidelines Titre testing against this strain is not commercially available, at least at present in the UK. It’s also worth being aware that other countries are slightly ahead of us in arranging vaccine importation and use for domestic rabbits. In Holland, vaccination has been underway with Filavac for several months before its use in the UK, and they also use the Nobivac Myxo-RHD vaccine.
Where can I send samples to get RVHD2 confirmed?
The following labs currently offer testing for RHD1 and 2. The OIE (World Organisation for Animal Health) guidelines suggest that liver is the best sample by far, but that spleen and blood are also good tissues to sample, as the virus becomes widespread throughout the body via the blood. The use of swabs to obtain samples from the tissues is possible, but to avoid false results, plain swabs (ie NOT in bacteriology medium such as agar gel or charcoal based material), with metal or plastic handles, not wood, should be used.
The use of faeces or urine samples or conjunctival swabs is less well evaluated, and we would not currently recommend testing via these methods when a test that is validated in the live animal (blood) is available
