Hiya
Crossing fingers and toes for you all. Such a worry
What did the vet say last night?
If unhappy with Petersfield one, seek a second opinion here:

Don't know if you have had time to read this yet, but Vicky posted on our bunny group:
There is a strong relationship between 'Ileus (gut slowing)' and 'caecal balance (the balance between good and bad bacteria in the bunny's caecum)'. The two are interlinked....if you get caecal dysbiosis (the caecum gets out of balance - more bad bacteria multiplying) then this can trigger ilues and gut slowing. Similarily, gut slowing (ileus) can cause the caecum to get out of balance and caecal dysbiosis. Both can trigger gastric stasis as one often effects the other.
The caecum in the rabbit gut is highly important in rabbit digestion as it is where nutrients are processed and your bun produces a 'caecotroph' which it will normally, when in good health, reingest directly from the anus. You may not even be aware your bun is doing this as the reflex to bow the head and eat the caecotroph happens very quickly and often at night or late morning. It is the good bacteria in the caecum that ferment and process the nutrients. When the balance of gut flora (good and bad bacteria) get out of balance, things can start to go wrong, often this is noticeable by bunny producing excess caecotrophs that are discarded and not eaten (although there are other causes for this too...such as obesity - can't reach it's bum!, teeth problems, and following antibiotics or illness the caecotrophs may not smell or taste right so are discarded)
The other main cause for too many excess caecotrophs are diets too rich in starchy carbohydrates....that tend to linger in the gut, and diets simultaneously too low in fibre - large particles that pass throught the gut quickly and keep gut motility at its optimum.
Too many starches are things like ...too many pellets, sugary treats (including fruit, carrot root itself (not the tops) cereals, bread etc) Not enough fibre means...not enough hay/grass. Rabbits are hindgut digestors and have evolved to eat large amounts of tough fibrous material. Around 90% of your bunny's diet should be quality grass hay or grass - to keep the guts moving and the caecum in balance (not to mention wearing the teeth adequately - nothing else does this like hay/grass).
Buns producing soft squishy stools that don't even resemble caecotrophs (bunches of grapes) are actually producing malformed caecotrophs indicating that things are really out of balance and need sorting. The best thing for this is to cut right down on pellets and get your bun eating lots of quality hay (although if you bun isn't used to lots of hay you must do this gradually so they don't starve or lose weight) Also, leave off the veg for a day or two until things settle back to normal.
Antibiotics can also kill of the good bacteria in the gut and bring on an episode of caecal dysbiosis so often at these times a pro/pre biotic is a good idea.
Too much fur ingested or a foreign object can cause ileus or impaction, or a full obstruction. Lower gut obstructions tend to have a better prognosis than higher obstructions. The only way to tell is with an X-ray, and even experienced vets find it hard to differentiate and therefore, gut motility drugs are vital for all cases, even though in higher obstructions they are not recommended, often you have to risk it and administer them anyway i understand.
So, this is often what lies behind the trigger for an episode of GI stasis. The best thing you can then do is take all steps to prevent the above - make sure your bun has a diet very high in fibre (hay) and low in starch (only a small ration of pellets per day) and lots of leafy greens.
However, ileus or caecal imbalance leading to GI stasis normally requires a trigger, and the most common trigger is STRESS. Stress can take lots of different forms....if you have a lone house bunny and you go away for a wkend say, this separation can be enough to trigger an episode...you therefore, need to make carers and bunny sitters aware of what to look out for. Stress such as injury, trips to the vet, operations....AND GA's (general anaesthetics) can all trigger ilues or gut slowing. Pain - is the other big trigger. GA's actually have a slowing effect on the guts in addition to stress, and pain makes a bunny not want to eat...and a bunny not eating goes into ileus and stasis. Any stress releases catchecolamines (i think?) which have a slowing effect on the guts so just be aware of things that can trigger an epsiode.
Often ileus comes on over a few days.....it is unusual for it to be instant, and over the course of a day or two or even weeks, you will notice reduced droppings, smaller dropping and eventually a bun who appears huddled and lethargic and disinterested in eating - this is where you need to seek treatment, if not before.
Things i have noticed:
- Bunny hides somewhere or sits somewhere they never normally do, unusall place behind a sofa they never sit behind normally etc. for example
- Bunny pushes their tummy to the floor (researchers have found this to relieve pain from gas in the stomach - BLOAT)
- Bunny gets up and down and up and down and can't get comfortable (again due to the BLOAT in their tummies) But ears are up as they aren't relaxed and often eyes wide.
- Bunny will NOT accept any food even their favourite treat - seek medical attention NOW! DO NOT wait until morning - you will have to go to the on call out of hours vets.
Pain relief is VITAL - it makes ALL the difference. Sometimes, pain relief given very early on - when bunny is still alert and simply pressing tummy to the floor and refusing food can actually prevent an episode coming on. Bunnies in pain do not eat and this makes the ileus worse...if you give pain relief quickly bunny may eat themselves again within half an hour and the guts start moving again and disaster averted.
If your bunny is floppy and unresponsive then you need URGENT attention. Do not underestimate the value of pain relief, buns are prey animals and often do not show pain so as Clare said do not be fobbed off - a good vet will give it immediately for these symptoms.
If your bun won't self eat and is in stasis then they need the following:
syringe feeding, gut motility drugs and pain killers, to be kept warm, calm and quiet somewhere safe and dark if poss, and with their companion bunny if they have one. Heat pads or bottles filled with hot water wrapped in towels will help - buns lose heat quickly as they have small volume to surface area. Remember, a sick bun can't respond to heat or cold properly so you must make sure any heat pad is not scolding them. Some vets will hospitalise your bun and this may be necessary, but if you feel confident treating at home then most buns have a better prognosis back home in familiar surroundings.
There is another condition which mostly affects very young rabbits below 6 months of age called Mucoid Enteropathy - this is different to Gastric Stasis apparently and often more fatal, but has similar symptoms. Mucus production in the stools or from the bottom seem to be indicative. But I understand this can also trigger gastric stasis.
