After I acquire the particular intrinsic conveyed by a corpse, I most often let my pets eat the rest (unless I need food). I've looked on the wiki, but haven't found anything about whether this allows the pet to also acquire that intrinsic. It would be nice to know if my large cat/dog/warhorse is or isn't fireproof before entering Gehennom. This question extends to Giants for strength, and any other corpse-borne benefits as well.
Do pets (particularly, horses,dogs, and cats) gain intrinsics and/or or other benefits from eating corpses?
