Quote: from FlatSeasonLover on 4:21 pm on Mar. 6, 2007[br]Going off topic slightly, but what animals can and can’t vomit? <br>
As a rough rule herbivores (cattle, horses, rabbits) do not vomit or only do so as a ‘last resort’ when very seriously ill; carnivores (cats, dogs) frequently, and often deliberately, by consuming a ‘foreign’ food such as grass; and omnivores (us, pigs) only when having a stomach upset.
Ruminant herbivores practice a controlled vomiting of sorts when chewing the cud (ruminating).
I would guess that horses, being non-ruminant herbivores, don’t vomit for the same physiological reasons that allows them to breathe only through their nose and not their mouth i.e. they can’t pant.
I believe birds don’t chunder either.
