Apologies first and foremost for pulling up a post from so long ago
But this is exactly whats happened to my Jazz bun, right down to the diagnosis. I know he has had no injury as I have had him since he was young (from a petshop where he looked so sad in a tiny glass cage) He seems to be going from being ok ish, just a bit stiff looking on his back legs - like he's holding his knees together to his left leg seeming to have no control at all - which is very distressing to see and is breaking my heart.
Was there any joy with this bun or any of the other ones you guys spoke about? or is it a case of making his life comfy and easy until he tells me he's had enough
