This is 1 massive topic. I'm assuming that your bun keeps getting stasis & a full examination by a good vet shows no underlying cause - PAIN from anywhere.
Some buns are gassy - have symptoms for an hour, usually relieved by hopping around or a bumpy car journey to the vet. Certain foods are notorious for producing gas - brassica family, & high starch foods.
It's a condition which can easily become bloat very fast, so we can't sit around waiting
long for 1st. aid to work.
I guess it then boils down to
a) Painful to eat - molar spurs can't always be seen without a GA. Then there's tongue mouth ulceration caused by them - (should be seen.) But unless they are treated your bun soon gets into very big problems!
b) "Stress".
1) Physical - sudden changes in temp. sudden changes in diet etc. moulting. Some buns have a slow gut at the best of times, (they are often avid wood pulp eaters = cardboard /paper/ wood of hutch) a few have a sharp bend in the gut.
2) Psychological - fear of predators (WE may know they're safe but they don't) deaf/blind buns are particularly at risk, change in routine (eg. bonded bunny parent stays out all night :lol
, bereavement,
With my bun it often takes several minor factors in quick succession to cause stasis. It can take years to understand our individual buns.
What is happening rock bottom?
In many many cases, there is overgrowth of the "wrong sort" of bacteria in the caecum.
If the bowel slows down they multiply & start to cause issues - some bacteria make toxins which slow the gut further & others ferment the ingesta to produce froth. Bunny feels full & doesn't want todrink or eat so much = bowel slows down even more, & bacteria multiply more until a critical level is reached when they cause major symptoms.
Several of us have successfully reduced the frequency & severity of stasis episodes with a strict diet. NO commercial treats. My bun is'nt allowed ANY sugar(fruit) or starch (eg carrot or grain treats) at all. Some find that spring greens/cabbage/broccoli are the culprit.
Last Autumn it was found by PL that veg from supermarkets which is prepared for marketing by washing it in
chlorine was adversely affecting the bacteria in stasis prone buns.
The natural gut stimulant for buns is plenty of regular excercise - like us.
High fiber in good hay. Several of us have had much success by adding fresh/dry bunny safe tree leaves to the hay. Most buns prefer hawthorn (remove the buds/flowers/berries) [Blackbery leaves & raspberry if you can get them are the traditional remedy].
"Keep the gut moving & keep the wrong bacteria under control with a regular flush out." We can't get rid of them cos the bun has to eat their caecs, but we can keep them to levels where they don't cause issues.
It is very important that the bun drinks plenty so a heavy bowl as well as a bottle can help.
Never worry that a stasis bun will miss the commercial chocolate dops or grain treats - you'll be amazed how they go crazy for their leaves.
