    they absolutely could reverse peristalsis just like any vertebrate.

    AFAIK Horses cannot vomit, and I also was told that mice and rats cannot vomit.

      What I’m describing isn’t actual vomiting either, but more like regurgitating. Rodents can do that, though horses can’t (because they can’t even belch, they’ve got a one way valve).

      Ruminants like sheep and giraffes also don’t externally vomit but they do internally vomit which makes stuff change chambers in their stomach.
