The check for pets eating corpses that polymorph them doesn't seem to include genetic engineers at all - possibly an oversight, and a reasonable enough one considering the genetic engineer isn't a shapeshifter itself. A yellow dragon of mine just became a lichen from doing so (which is infinitely more annoying than it eating the corpse to begin with because isn't that stereotypical), which prompted me to make this issue.
