Hi there, I’m sorry to hear about your Nethie’s health issues. It is always hard when our pets get older. I’m not sure what is usually prescribed for arthritis pain in rabbits, but did the vet try an alternative pain relief?

While vet prescribed medication is obviously recommended and I must recommend it before anything, in a case where this is impossible some plants/ herbs have natural pain relieving properties. Nothing if course to the extent of medicine but it may be a worthwhile alternative to read into. I believe willow and birch are two of these. They shouldn’t be fed if bun is currently on meds but can be used otherwise, it may not help but if bun can’t have meds it’s worth a go since they are bun safe plants

What are you using for bedding in his cage? I’m wondering if something more absorbent may help his skin and help for regrowth. Maybe some vetbed or something similar.

ETA: I’m just reading that the flower heads of dandelions also have pain relieving and anti-inflammatory properties.  And of course all things in moderation and take care when introducing any new foods. 

Unsure which litter box you use, but would a low-lip help? I have this one: http://www.amazon.com/Marshall-High-Ferret-Litter-Colors/dp/B0002AROVQ/ref=sr_1_5?ie=UTF8&qid=1527774308&sr=8-5&keywords=ferret+litter+box

— The low lip is quite short, so it may help.

Hi, I don’t have a lot of advice. Just wanted to say it sounds like you are doing everything you can. Except for the height of the lip of his litter tray as Wick suggested looking into I don’t have anything else. But I do empathize with you. Everything does sound age related. And it’s tough watching them suffer the age related issues because you know the quality of life isn’t what it used to be. One does feel so sorry for them. But it’s really good that he is eating, drinking, and pooping well and the vet says he is doing well also. 9 years is really good…he’s chugging right along.
