Just thought I'd update as Muppet seems to be recovering really well - it's nice to have the good stories too!
He spent the early evening, sprawled quietly in his cage. Gradually started nibbling with more enthusiasm. By 11pm, he had some pellets but mostly concentrated on hay and veg. Most importantly, he'd done a nice heap of bunny poo :lol: Some a bit smaller than usual but all healthy looking. And he was looking much brighter.
This morning he's definitely brighter and has come out of his cage for a wander around. No running or binkying though (thank goodness!!). Has a good rest after each exertion. Still not eating pellets tho (which is unusual) but OK with hay and veg. No poo yet though.
Am keeping a close eye on him, as presumably the painkiller starts to wear off from now on.
