Thank you so much for all the replies whilst I was gone.
Ok, we're back- full contingent (thankfully- I thought we may be minus one).
Basically, the vet isn't sure. She can't find any evidence of injuries and he seems in excellent health otherwise, he just can't hop properly. She feels that it's not neurological, so therefore it's likely to be a soft tissue injury.
No idea what he may have done. He was hunky dory this morning.
Tis very sad. Thankfully he is eating and alert, just unwilling to move and unable to move when he tries to.
It was a vet I haven't met before. Very thorough as a vet but I wasn't comfortable with her bunny knowledge. She was better than an average vet though, just not either of my normal vets. I'm fussy. :lol:
He's had some Metacam so now we just wait an see if that helps him.
He looks very reminiscent of my Rosie Po.
