In a giraffe, it would come out of the fourth stomach and it would sort of bypass the third stomach, and go into the first and second. It's extremely rare for the vomit then to go any further than that. So, in a sense, yes, giraffes can vomit, but it's very, very rare that it actually comes out of the mouth.
