There are a number of web sites and published works, with a lot of different and often contradictory causes for bloat in rabbits. Many seem to be reflecting opinions and best guesses. The few works I found with scientific research included in their documentation did not indicate an identifiable cause or causes.
Two facts that I believe are not in dispute:
- rabbits cannot vomit (or burp)
- bloat is nearly always fatal (and painful)
Answers quoting a web page saying bloat is or is not related to GI stasis, are discouraged. Answers with reliable references including scientific inquiry, or personal experience where one or more specific (irregular) changes occurred in close proximity to the event are encouraged.
