Arthritis of the Jaw - Quality of Life

Hi everyone,

Long time no post. I feel bad coming on here just to ask for advice again, but I find RU to be the most warm, helpful and educated rabbit community on the internet.

I'm really just looking for some advice and reassurance about how to proceed with my rabbit, Lily. The last time I posted, she was about to have a CT scan after a major health scare which resulted in days of hospitalisation and an emergency dental. We had all sorts of worries about what was going on in her mouth, let alone some abscesses suddenly appearing on her elbows. This was back in August 2023 and we had also just moved house, so it was an overwhelming time to say the least.

The CT scan revealed that she has arthritis on one side of her jaw/TMJ. This is what my vet wrote to me when they received the scan results:


"The report shows that the dental disease is not too severe thankfully, there is mild/moderate dental disease present, but thankfully, no abscess associated with a tooth root etc. Any pus observed likely to be as a result of infection in the ulcers in the cheek, secondary to the dental disease. It would be interesting to see whether there is still any pus visible.

But the CT has revealed the likely cause of Lily not eating - she has very severe arthritis in her left temporomandibular joint (the joint between the skull and the jaw). There is new bone formation there but also sclerosis (where the joint has started to "fuse"). I think this means that opening and closing her mouth and chewing are likely to be quite painful. It's a difficult problem for us to solve - I don't think we can cure it, it will be a case of ensuring suitable ongoing pain relief to try to provide her with comfort and potentially, may also involve us offering her some softer foods on an ongoing basis. If she'll take something like Oxbow or Emeraid from a dish, it may be worth offering this. If she is struggling to eat/losing weight despite pain relief, ongoing syringe feeding may need to be considered. Unfortunately, if we get to a point where we can't keep Lily pain free, then at some point we have to consider quality of life."



Going on from here, we decided to try Lily on some strong medication to see if we could manage her pain, with the mindset of we will only keep her going if she is not suffering. We started Lily on a combination of Loxicom and Tramadol, but found that the Tramadol was making her really drowsy and spaced out. It was also costing almost £250 every three weeks, which was not easy for us to afford on our income. On the Tramadol it was hard to tell if she was in pain or just spaced out.

Subsequently we had to change vets, as our wonderful previous vet was now over 2 hours away. Thankfully we found a great new vet only 5 mins from our new home. After going down a rabbit hole, I asked my vet about Calpol instead of Tramadol, and we tried that alongside Metacam with success. I educated myself on the rabbit grimace scale and have been carefully keeping an eye on her body language and how well she was eating. She was doing really well given her condition up until November 2024 when she suddenly seemed off again. We booked her in for a dental and she had a couple of spurs removed, but nothing severe. There were 8 months between dentals, which to me seemed quite a good amount of time given her arthritis.

However, she has gone downhill gradually since November. Her weight was maintained at 2.5kg up until Nov, but has gradually slipped to 2.3kg. She is VERY affected by temperature, so we keep the door to their room closed at all times with a temperature gauge and their own special plug in heater. I try to keep the temp above 20C at all times, although there may be a few hours overnight where it drops when I'm asleep. As she can only eat grass, not hay, this is another struggle. I am finding it difficult to forage enough on a daily basis. So much of the grass is covered in rust, or has simply died back to nothing. Luckily my neighbour lets me hand cut grass from his field, but I know she's not getting enough to keep the weight on, and I'm worried it is also affecting the speed at which spurs are re-growing.

They were both vaccinated last week, and the vet said he could see a slight edge on one molar forming. I'm wondering if this could be enough to make her 'off' again. She's not eating her grass with relish like she did in the summer. I'm also concerned that her mouth always feels damp to the touch. I have never had a rabbit 'drool' before, but I wonder if this is the early stages of drooling.

My biggest fear is that the arthritis has worsened in the last year and half, and that the meds aren't enough for the pain anymore. She still eats pellets, dried herbs and fresh brambles/plantain/leafy stuff okay. Could it just be one spur causing all of the problems, and the cold/not enough grass meaning only 2 months have passed and she needs another dental already?

Any advice or thoughts would be hugely appreciated. They are both (Lily and Maple) almost 9 years old now, so getting on in age, but Maple is in good health. The hardest thing is that they are VERY bonded as sisters, and I dread to think how Maple would cope without her sister if we had to make that decision. Partner and I don't think we are in the right place for more rabbits at this time; financially we have spent thousands on Lily's condition. The house we moved to needs a lot of work and we'd like to get up straight before potentially adopting another pet in the future.

Thank you so very much for reading. I'm going to see if I can find some photos from the CT scan to upload as well.

If there's a confirmed spur, it could be enough to cause issues and is something that can be sorted out.
Meanwhile, are you syringe feeding at all? I would increase the quantity of whatever she will eat and add some syringe feeds to try to get her weight back up a bit. Thankfully, everything is starting to grow again now - so forage is getting easier to find. She may be finding it much harder to eat grass if she doesn't have full jaw movement, so you may have to make adjustments there - maybe cut it into tiny bits and mix with CC on a saucer?

I'm not syringe feeding as she finds being syringed her meds twice daily really stressful, to the point that she'll hide the moment I enter the room. So I've been trying to reduce her stress as much as possible. If I gave her more pellets she would happily eat a whole bowl full, so I could try that, but would have to make sure she is away from her sister who would also scoff them otherwise.

I suppose my worry/fear is that if she doesn't eat enough grass, she'll keep getting painful spurs and the cycle with continue. It is why I have been questioning quality of life, but equally she may be a lot better in the Spring when I can forage a lot more. We live on a smallholding and are very rural, so in Spring/Summer/most of Autumn I can get an abundance of greens for them, which is great.
 
I agree the spur may be bothering her so a dental may get her back eating grass. Though also provide her with more pellets. This may buy you time until the weather gets warmer and forage easier.
Sending vibes.
 
I can't really offer any more advice, just wanted to send lots of vibes for your girl, she's lucky to have you caring for her so well.
 
Just wanted to pop in and say hello :D Living on a smallholding sounds very interesting!

I'm sorry about your concerns with Lily, which I completely understand. Plants are starting to show signs of new growth, so it's only going to be a few weeks before there's a lot of lushness outside.

Regarding feeding Lily, I would just try to give her more of what she's able to eat, whilst preventing Maple from eating too much. I would recommend giving her Fibafirst sticks if she'll eat them. Unlike pellets, a bunny can run off with one and eat it. They also are reasonably calorific and so could prevent her from losing too much weight.

I would also consider getting the spur sorted out.
 
Hi everyone, I know that this reply is really late and I apologise for not logging back in sooner. Sadly one of my other pets has been really unwell, recently diagnosed with a chronic illness, and it's been a difficult 2025 so far for me to say the least. But I wanted to share a positive update about Lily.

Shortly after making the above post, Lily had a dental and one spur was successfully removed, which was likely causing her pain. She has improved hugely overall as the weather has warmed and we have a much larger variety of fresh forage to feed her. She's eating much more grass than she could manage this time last year (has gone from eating only soft leafy grass to hard stalky grass) and is even eating some bits of hay again.

Lily is now 9, so to see her improving like this against all the odds is remarkable. I think the biggest game changer overall has been the Calpol, but I am also determined to begin drying forage for her ready for this Winter, and to improve the insulation in their room in the house. I think keeping the joint moving is key, so keeping it 1. pain free and 2. as mobile as possible through lots of chewing is keeping her in good health overall.

For me, learning about the grimace scale has been vital in understanding when she may be uncomfortable again and need another dental. I'm really learning to read between the lines in terms of her body language, facial expression etc.

I thought that you might like to see some photos of how good she's looking. Lily is the fawn bun, Maple is her tortie sister.





 
Wonderful to see Lily looking so well & to read such a happy update ❤️ I hope your other pets chronic condition can be managed successfully
 
That's so good to hear the update! ❤️ It's amazing how you've managed her condition and kept her in good health/spirits despite the difficult diagnosis. And Lily sounds like such a fighter too. I never even knew rabbits could get arthritis in their jaw!
 
Thank you for sharing the positive update on Lily and sharing the lively photos of Luly and Maple. It is so good to read she is doing well and you are able to monitor her level of comfort successfully.😍
 
Thank you everybody for your kind words!

I didn't know that rabbits could get arthritis in their jaw either - the vet thinks it developed from an old injury, which must have happened before we adopted them both (when they were age 4). It's almost been 2 years since she went into the hospital overnight and I'm beaming with pride at how well she is looking now, it does feel like a miracle and I hope that this thread may help someone else in the future if their rabbit has a similar issue.

A nice silver lining is that since becoming house bunnies, they have both gone from being quite feral to actually really friendly - they do stay in their room despite the door always being open, but no longer hide when we walk in. We've tried to make the twice daily meds 'fun' by giving a sprinkling of pellets afterwards, and often Maple will be tugging on my trousers whilst giving Lily her syringes, as she knows what's coming next :ROFLMAO:
 
Does anyone have any experience of just one spur causing a lot of discomfort?

Lily has had another dental today (4 months between the last one, so not too bad of a gap) - the vet said that her mouth was very clean looking overall, with just one tiny spur which was burred off.

Her symptoms in the past week or so, which made me think she needed another dental, were suddenly not wanting the syringe in her mouth for the meds, sometimes showing pain posture when resting (hunched back, scrunched up face) and scrunched up face when eating sometimes.

The vet had an honest discussion with me that it may be the arthritis has developed to the point of being too painful for her meds to handle. She said that her jaw wasn't very easy to open compared to the average rabbit - it was very stiff.

We're going to see how she goes in the next couple of weeks, but given her age and the severity of the arthritis, I know in my heart that we don't have a gigantic amount of time left with her now.

I'm also very concerned about how Maple would cope without her, as we aren't in a position to adopt another rabbit for the foreseeable future :(
 
Yes, I've had rabbits who were affected by a small spur which needed regular burring. 4 months is a decent gap between burring.

There are various other treatments available for arthritis (physio, laser, etc). It's definitely worth asking around as I know some people on here have had a positive response to some of these treatments. There are also various meds available. Can you get a referral to a rabbit specialist to explore further options?

Thank you, hopefully it was just the spur then and she'll be feeling better in a few days! We'll see how she goes. I do know an equine massage therapist who also does laser on dogs locally, I will discuss with her again.

I'm also aware that Lily's arthritis is very severe though, so what can be done going forward may be limited. We have tried pretty much every pain med available to rabbits, and have found that a combination of Metacam and Calpol works best for her :)
 
As her jaw is very arthritic, it may well be bothering her more for a few days after a dental procedure as the vet will have had to push the limits to allow for access to the spur, and it will be very sore. The same may apply to other areas due to the unavoidable additional handling, etc while she was at the vet. I hope she's more comfortable in a few days.
