Yeah agree that it's best to be careful. As for the slow bloat, I don't know what else you'd call it when the animal's visibly as distended as a full-term triplet-bearer, but stays that way for months, emitting a lotta gas, unable to lay down properly... But not pregnant. It is gas in the bowels, or has a symptom list including a lot of gas, but it's not the sudden bloat that kills them quickly. I don't know what you'd call it but I've seen it in older animals with degraded teeth.
Also the lamb I have I got as a very, very sick orphan who had severe gut issues including cross-contamination from human fecal matter and pulpy kidney, and she scoured nonstop for the first two months of her life, and remained bloated on almost a daily basis for the same time. Farting, burping a lot. She'd 'toot' if she sneezed, she was so full of gas. She still spends most of her time bloated. But at least she's pooping normally now.
