Just got back.
Typically he nibbled some hay just before we left but i took him anyway.
The vet couldnt find anything wrong. Theres no blockages, no gas, his guts are moving although his tummys empty. Teeth are fine and his temperatures normal, i reckon if wed gone a few hours ago it would have been low, we've had him wrapped up next to a heater.
He gave him a dose of metacloperamide to be on the safe side and some probiotics.
We've got him home and set him up as normal. He is one ANGRY bunny and is generally makung a nuisance of himself, which is great news. He just hopped into his litter tray and nibbled some more hay. No poos yet but i dont expect them for a while.
I am so frickin relieved, there was a moment there when he seemed to give up and I really thought i was gonna lose him. I
shudda known he was way toi stubborn for that
