Hi- am posting in case anyone recognises this scenario. I have an 18 month old rescue lop bunny who every few months goes off his food but recovers within 24 hours after vet intervention (gut motility stimulant injection). Unusually, in past week he has had 3 episodes - the first seemed mild and i monitored him and he bounced back within hours. The next morning he was binkying in garden and came running to me for food but then wouldn;t eat and within minutes was sitting hunched up and withdrawn in the hutch, ignoring his bunny sidekick. He was back to normal later that day after vet intervention but last night, same scenario occurred... half an hour before lockdown he was 100% ok in garden eating grass then when i went to shut them in for the night he was in withdrawn mode and refused his treats and pellets. By middle of the night he was accepting pellets and this morning he was running about outside on great form and eating everything in sight. They have been on vet advised diet past few weeks - fewer pellets tapered down over time and veg reduced to leafy greens - unlimited hay, couple of bowls of readigrass, free access to grass when they're out (few hours per day) and couple of apple treats at lockdown. The only other change to his diet has been the introduction of horse hay (which they prefer to commercial bunny hay though both are still provided). He had a dental 3 weeks ago. He will occasionally leave caecotrophs in hutch .. even since the 'diet'. Any ideas what could be causing him discomfort quite suddenly ? Anything you'd recommend i do to stop this happening or is he just going to be a bunny with persistent gut issues? Sometimes he eats like he can't get food into him fast enough (compulsively/obsessively) - my other bunny loves food but is not like this - might he just have gut ache post overeating compounded by recently increased hay/grass intake ? I'm assuming digestion-related issue given his past history but might he have intermittent pain elsewhere that might present like this ? thanks.
